To identify the type of machine, it has a white sewing
head with six needles, and large bobbin case. The serial number will start
with 510_ _ _ for trimmer machines and 480_ _ _ for non trimmer machines.
THE MACHINE WON'T COME ON. THE DISPLAY IS BLANK:
- Check the power source. Make sure it is a working outlet.
- Make sure it's plugged in.
- Check to see if the fan is on at the back of the machine. If not,
again check the above two items.
- Check the Power Harness Connector in front of the Power Supply for a
strong connection. It is located down inside the compartment under the
Keyboard Assembly.
THE DISPLAY IS BLANK, AND THE FAN IS RUNNING:
- Lift the Keyboard Cover to check to see if the Keyboard Ribbon Cable
is connected to the bottom of the Keyboard PCB. Try adjusting the
Intensity Adjustment at the right side of the Keyboard. See pages 2-2
through 2-3 in the Technical Manual (PN# 110041-01) for instructions.
- If none of the above fixes the problem, it is best to test the Logic
Voltage at the XYZ PCB under the back left cover opposite the Keyboard
Cover. Remove the cover, and test the voltage at XYZ PCB with part
number 003663-01 located closest to the front of the machine. The test
points are located at the upper edge of the board. Use a Digital
Multimeter to perform the test. Disconnect the Computer Interface Cable
at the back of the machine before test & adjustment.
- The Test Points are located across the top of the XYZ Interface PCB.
Choose TP4 (GND) and TP5 (+5V). Do not cross the test leads from the
meter when connecting them to the test pins on the board. Note: The
machine must be powered on for this procedure.
- The voltage should be set at 5.00VDC to 5.05VDC. To tune the voltage
have the Keyboard raised, and laying on it's face. Do Not Disconnect the
Keyboard Ribbon Cable to perform the test.
- The adjustment Pot or Screw is on the left side of the Power Harness
Connector down in front of the Power Supply. Refer to page 2-4, Figure
2-3. Use a small screwdriver similar to the one that is used to replace
needles to make the adjustment.
- Turn the adjustment screw clockwise to adjust up to the required
voltage (5.00VDC to 5.05VDC).
- If there is little or no voltage showing on the Digital Volt Meter, it
would be best to call your distributor for a replacement Power Supply.
The part number is: 005570-01. The Technical Manual has the information
explaining how to replace the part.
- The part number for the manual is: 110041-01. See Pages: 3-15 through
3-16, and adjustment information on page 2-4. Also refer to Parts
Replacement Instruction part number 110155-01.
THE KEYBOARD DISPLAY IS STILL BLANK:
- If the Power Supply is replaced, and the Display is still blank, and
the voltage test at the CPU reads correctly, replace the Keyboard PCB.
The part number is: 384309-11. The Technical Manual has information
explaining how to replace the Keyboard. The part number for the manual
is: 110041-01 (pg.-14 through 3-15), and pages 2-2 through 2-3 for
Display Intensity instructions.
- The Keyboard has been replaced, and the Display is still blank.
Replace the CPU PCB. The part number is 005601-01.
- If the Display doesn't come on after replacing the Power Supply,
Keyboard, or CPU Bd., call your distributor for a service call.
THE DISPLAY IS ON, BUT BY PRESSING ON THE KEYS NONE OF THE MENUS WILL
CHANGE. THE ARROW KEYS WON'T RESPOND EITHER:
- Try turning the machine off, and then on again.
- If the Keyboard is still inoperable, use the information on the first
three pages of this guide to try to determine the cause of the error.
THE PANTOGRAPH MOVES ON IT'S OWN, BUT ONLY FORWARD OR ONLY BACK. THE
OTHER POSSIBILITY IS THAT IT MOVES ONLY LEFT OR ONLY RIGHT:
- Replace the Keyboard PCB, as one of the keys may be sticking,
384309-11.
THE MACHINE WON'T STOP SEWING IF THE STOP KEY IS DEPRESSED OR FRAMES
BACK ON IT'S OWN, AND WON'T STOP FRAMING BACK:
- Turn the machine off and wait at least 15 seconds, and turn it on
again. Use the Head Timing Menu to "Go to Head Up" when the
machine powers up. Use the Power Fail Rescue Function in the HOME MENU
to retain the design, and try to finish the design. If the machine still
won't stop using the STOP Key or stop Framing Back, replace the Keyboard
PCB.
THE MACHINE STARTS SEWING ON IT'S OWN:
- If this has happened more than once replace the Keyboard PCB, as the
START Key is probably engaged when it shouldn't be. Part # 384309-11.
- The Pantograph moves back and forth too fast or too slow. The X
Carriage moves the hoop left & right too fast or too slow.
- This is when the Arrow keys are used to move the pantograph when the
machine is not sewing so alignment of the hoop can be changed.
- Depress the FAST/SLOW Key to reset the pantograph jog speed so it
moves slow or fast. This is not a fault of the Keyboard. It is a jog
speed control for the pantograph not a sewing speed control.
THE MACHINE DISPLAY FLASHES "EPBIOS" & "UNIT
NUMBER", AND THE MACHINE WON'T COME ON LINE:
- Check the EDS system in the computer to see if the machine is still
enabled. If the machine is to come on line it must be enabled in EDS
whether EDS2 or EDS3 is being used. If there is only one peripheral,
enable a second one in peripheral menu to make sure EDS is scanning for
peripherals. Use page 10-3 in the EDS2-manual, and page 11-2 in the
EDS3-manual to find out how to enable the machine(s).
- Check the configuration of the machine. Use the information in the
Technical Manual (PN#110041-01). See pages 1-6 through 1-8 to
re-configure the machine. If the machine type (EMC6ML [NON TRIMMER] or
EMC6MTL [TRIMMER]) or the Unit Number is incorrect, the machine won't
even request a download to come on line.
- Check the Interface Cable that connects the computer to the sewing
peripheral for strong connection or if it is connected at all.
- This cable may be damaged. The part numbers for the various lengths
vary. Call your distributor for information.
- If the machine still won't come on line, call your distributor. The
CPU Bd. in the sewing peripheral may be at fault.
- The other possibility is that the Network PCB in the computer may be
damaged or the EDS software is not configured properly. Refer to the
proper EDS manual for configuration.
THE PANTOGRAPH WON'T MOVE AT ALL WHEN SETTING HOME:
- Test the Logic Voltage as explained on pages 1 of this guide first.
The XYZ Amplifier PCB controls all motors in the machine. The following
is a list of the voltages on this PCB and all should be measured for
correct voltage. With the power turned on, check that all three LED's
are on (DS1 = 5V, DS2 = 15V, DS3 = 24V). Set a Digital Volt Meter to DC
volts range and place the black test lead into test point TP5 (GND).
Using the red test lead, check the following test points for correct
voltages: TP1 = +24V, + 1 volt TP2 = +12V, + 1 volt TP3 =
+15V, + 1 volt TP4 = +5V, + 0.3 volts
- If the Voltages test correctly, try configuring the machine again
using the Technical Manual on pages 1-6 through 1-8. Manual Part
Number:110041-01. Re-configuring the machine is a very good way of
resetting the machine for most errors that are out of the norm.
- If any of the voltages are not present or very low, replace the Power
Supply (005570-01) or possibly the XYZ Amp PCB (003663-01). See the
Technical Manual for replacement instructions. Pgs. 3-13 for the XYZ
Amplifier PCB and 3-15 for the PSU. Also for the PSU there is a Parts
Replacement Instruction available part number (110155-01).
- One or both of the motors could be damaged. The part number for the X
Motor is (005021-01) and the part number for the Y motor is (000465-01).
- It would also be a good idea to check the X & Y Axis Motor Wiring
connections
SELECTING A HOOP SIZE:
The machine errors when doing so.
- If "Machine Running" or "Run Job Error" shows when
trying to select a hoop size, push the MENU Key until "RESET
MENU" shows. Push ENTER, and "System Reset" will show.
Push ENTER again to reset the machine. Push the MENU Key until reaching
the Design Menu, and set up the design again.
EITHER THE X OR Y AXIS OR BOTH WON'T MOVE WHEN TRYING TO:
- Use the same instructions on page #3 to troubleshoot this error.
THE PANTOGRAPH UNLOCKS MID-SEWOUT:
- Check to see if the garment has caught on any part of the machine.
This will cause a stoppage, as any hesitation in the X or Y Axis
movements will cause the Pantograph or X Carriage to unlock as if the
motor is turned off. It is built into the software to do so to protect
the operator, and the machine from further harm or damage.
- If the garment has gotten caught in the chassis or there is a Bird's
Nest of thread under the Needle Plate, push the Stop button. If it won't
stop sewing, turn the machine off. Wait 15 seconds, and power it back up
again. Try a POWER FAIL RESCUE to see if you can recover the design.
- If the error continues, and there are no apparent reasons for the
stoppage in the pantograph movement, turn the machine off. Remove the
Keyboard Cover and the electronics cover and check all motor wiring
connections and reseat the CPU and XYZ amplifier PCB's.
- Remove the Left Side End Cap as seen on page (5-5). Check all wiring
connections at the X Interface directly under the Y Pantograph support.
Check all wire connections for tightness, and also see if any are
damaged. Check especially the flat braided cable (X Flex Cable PN#
003809-01).
- This cable transfers all power to the X Motor under the small cover at
the left side of the Black Pantograph Bar through the XYZ Interface PCB.
If the X Axis, (left & right movement-Hoop Holder), is the only
direction that won't move, replace the XYZ Amplifier first and then Flex
Cable, then the X Motor. If the Y Axis, (Back & Forth
movement-Pantograph), is the direction that doesn't move, replace the
XYZ Amplifier PCB first, then the Y Motor.
DESIGN LOSES REGISTRATION MID-SEWOUT OR JUST SEWS ERRATICALLY:
- Use all possible fixes listed on pages 6 & 7 of this guide.
Especially reconfiguring as stated in the Technical Manual
(PN#110041-01). See pages 1-6 through 1-8 to re-configure the machine.
X AND OR Y RACK NOT DONE:
This is the speed difference, mechanically or electronically, of the X
or Y Axis that is not in accordance with that of the design information.
- Oil the pantograph according to the information in the Operator's
Manual on pages 3-8 through 3-12 first if it hasn't been done yet or
lately.
- Try a Re-configuration as outlined on pages 1-6 through 1-8 in the
Technical Manual.
- Check all X & Y Motor wiring connections as suggested in previous
steps of this guide. Look under the right end of the pantograph where
the 3 oil holes are to see if the grounding nut is tight or there at
all. Make sure the X & Y axis move easily when the machine is
powered off. If not check both Motors, and all pulleys for free
movement.
- Test the Logic Voltage as suggested on pages 1 & 2 of this guide.
- If the error seems to be just the X Axis (Left & Right- Hoop
Holder Movement), follow step 5 of the PANATOGRAPH UNLOCKS MID SEWOUT in
this guide.
- The next step would be to call your distributor for a service call.
RACK LIMIT ERROR:
The hoop has moved to close to either it's X or Y Axis limit.
- Make sure the hoop size is selected in the Home Menu before starting
the design.
- Make sure the Trace function is used to avoid this error.
THE NEEDLE CASE JUST TRIES TO DRIVE OFF OF THE SEWING HEAD AS IF IT
DOESN'T READ ANY COLOR CHANGES:
- Test the Logic Voltage (5.00 to 5.03VDC), according to the information
listed on page 1 of this guide.
- Make sure the black Color Change Cam under the Color Change PCB isn't
loose on it's shaft. Use the information on page 3-34 of the Technical
Manual (110041-01) to see how to remove the Color Change PCB so the
Color Change Cam is exposed. There shouldn't be any left & right
movement of the cam at all. If there is, call your distributor to see
how to properly position the cam.
- Replace the Color Change PCB (PN#004125-01), as shown on pages 3-34 in
the Technical Manual (PN# 110041-01).
OFF COLOR INDEX ERROR:
The Needle Case is not positioned electronically & mechanically
according to the Color Change PCB for the needle to pass through the Needle
Plate Hole correctly.
- If the Red Color Change LED> on the front of the Tensioner Assembly
is on, the Color Change Cam needs to be rotated slowly Clock wise or
Counter- Clockwise to cause the red LED to go out.
- The Needle case is on color when the LED is out. Turn the Color Change
Cam Shaft Screwdriver Slot with a flat blade screw driver. (Located in a
small hole in the right side of the of the Thread Basket). When the Red
Index LED is out, push the MENU Key until the Head Timing Menu is
reached. Push the ENTER Key. Push the ALT & UP ARROW at the same
time, and the message should read "Go To Head Up".
- If the error persists check the Color Change Cam to see if it is
moving on it's shaft. Refer to #2 of the previous section in this guide.
- If the RED Color Change LED never goes out while rotating the Color
Change Screw, replace the Color Change PCB (PN# 004125-01).
- If the error continues, call your distributor for more assistance or a
service call.
CC TIME-OUT ERROR:
The Needle Case didn't move to the next needle in the Color Change
Sequence in the allotted time (15 seconds).
- If the RED Color Change LED is on, rotate the Color Change Cam
screwdriver slot according to the information listed above of this
guide.
CC-HEAD UP ERROR:
The needle bar wasn't in the full up position before the Color Change
System tried to make a color change.
- Again, if the red Color Change LED is on, rotate the Color Change Cam
screwdriver slot according to the information listed above of this
guide.
- When the LED is out, push the MENU key to go to the HEAD TIMING MENU,
press the ENTER key, and press the ALT & UP ARROW to make sure the
Needle Bar is at head up before continuing.
Z TIME OUT ERROR:
This error means that there is a stoppage of the Z Axis movement. This
means that the Take Up Lever stopped moving up & down, and the Needle
bar has stopped moving up & down, and the Hook has stopped rotating.
They are all part of the same movement.
- Check the hook to see if there is any thread in or behind the Hook
Assembly. If so, remove it. When the thread is removed, use the Head
Timing Menu. Press Enter once when reaching the menu, and press ALT
& UP ARROW simultaneously to "Go To Head Up".
- If the error continues, remove the Retaining Finger by removing the 2
flat head screws holding it in lace as seen on page 3-23 of the
Operator's Manual (PN# 110043-01). Remove the Bobbin Case, and try to
rotate the spindle on the inside of the hook assembly. It should rotate
independently of the hook assembly if the hook isn't bound by thread or
a broken needle tip.
- If the hook is bound, remove the hook from the sewing peripheral by
loosening the 2 larger slotted (flat head) screws at the back of the
hook assembly. See page ----- in the Hook Parts Replacement Instructions
(PN# ---------) to find the screws. If the inner basket of the hook
won't rotate by trying to turn the spindle inside, remove the curved bar
on the outside of the hook. It is held on by 3 very small slotted
screws.
- Try to remove any thread or needle tip that may have been hidden by
this bar. If the hook is still bound, replace the hook with a new one
(PN# 002611-01).
THE INNER BASKET ROTATES WHEN THE RESTRAINING FINGER IS REMOVED, BUT
THE Z TIME-OUT ERROR PERSISTS:.
- Remove the needle from the needle bar that is currently indexed. Turn
the peripheral off. Remove the back white cover with one allen screw.
This cover is on top of the sewing head behind the Thread Spool Saddle
Bags, all of the way at the back of the top of the machine. Once
removed, try rotating the toothed pulley with the black rubber belt
clockwise to see if the Needle Bar can be raised and lowered easily.
- If the pulley can't be rotated, remove the white cover on the face of
the Needle Case. Loosen the screw to the silver needle bar clamp inside
the needle case on the needle bar that is currently engaged. Try to move
the Needle bar up and down.
- If it moves, try rotating the pulley at the back of the sewing head
again. If it still won't move try oiling all of the sewing head oil
ports. Let the oil soak in for an hour. Try rotating the pulley again.
If it still won't rotate, call your distributor.
- If the pulley rotates easily through 360 degrees, do so until all of
the Take Up Levers are even. The engaged needle will be down.
- Turn the peripheral back on. Press the Menu key. Go to the Head Timing
Menu. Press ENTER. Press the ALT and UP ARROW simultaneously. The
display should read "Go To Head Up". If it doesn't call your
distributor.
THE TAKE UP LEVERS MOVE UP & DOWN, BUT THE NEEDLE BAR WON'T COME
DOWN TO SEW:
- Check the White Jump Stitch Lever behind the left side of the Needle
Case. Make sure the lever isn't actuated as seen on page 2-9 of the
Operator's Manual. If it is, push it to the right so that it isn't. It
may be easier to see the position of the white lever when the Needle
Case is on needle position 6.
- Refer to the Parts Replacement instruction (PN# 110099-01) to see how
to check the adjustment of the Upper Dead Point Stops if the needle bars
still won't come down to sew. If the stops are in the wrong position the
needle bars won't come down to sew.
- If the engaged needle bar won't stay down when it is pulled down, call
your distributor as the Reciprocator may be damaged. It is what drives
the Needle Bars up and down when engaged.
NOT AT HEAD UP ERROR:
The Z Encoder has detected that Z Drive shaft isn't in position to be
at Head Up. A Take UP Lever, Needle Bar or the Hook may not be in the
correct position for this to happen. All three positions have to be correct
for the Z Axis to be at the head up position.
- Use the information in the Z Time Out section of this guide to try to
determine the cause for the error
MISSED HEAD UP ERROR:
- Use the Z Time Out Error information to try to detect the cause for
this error.
THE SEWING QUALITY OF THE DESIGN IS JAGGED AROUND COLUMNS, AND SOME
TIMES OBJECTS ARE MALFORMED. THE COLUMNS OR OBJECTS DON'T MEET THE FILLS OR
OTHER OBJECTS IN THE DESIGN:
- Check the hooping of the garment first. It may be too loose in the
hoop. The material may be to elastic to hoop tightly, so make sure that
there is enough backing being used. KK100 adhesive spray can keep the
garment in place with the backing, and make it more stable.
- Oil the pantograph at regular intervals to keep the assembly moving
smoothly. See the Operator's Manual (PN# 110043-01) on pages 3-9 through
3-13 for information.
- Check all of the X & Y Axis belts to see if they are torn or
breaking. If any of the belts are damaged, call your distributor's
Part's Department to replace the bad belt. Note: The Belt Tension meter
is needed to test the tension of the new belt(s). (PN# 992165-01)
- The X or Y belt tension may be too loose. Call your distributor if
this is suspected.
- The X Carriage or Hoop Holder Assembly may have too much play in it's
rollers. Remove the slide in Table Top, and look under the Black
Pantograph Bar. Hold onto the 4 corners of the X Carriage, and push
towards the front, and back of the machine to see if there is any play
in these directions. Refer to (Doc# 110178-01 Rev A) to see how to
re-adjust the rollers.
- Check the 2 Hoop Holder Pins on the X Carriage to see if either is
loose in the plate they are mounted on. If either of them are, call your
distributor as the X Carriage will have to be replaced. If either of the
pins is bent to one side the X carriage will need to be replaced.
- Check the metal hoop bracket on the hoop that is being used, as the
slots that fit the pins may be worn. The bracket may be loosely mounted
on the wooden part of the hoop. Try another hoop to verify a bad hoop
bracket. Make sure the wooden part of the hoop isn't cracked either.
Call your distributor for replacement hoops.
- If the Full- Height Jacket -Back Hoop is being used, don't set the
sewing speed over 650 as this hoop flexes due to the weight of the hoop
verses the Hoop Bracket, and the strength of the pantograph. Sewing at a
slower speed can make all of the difference.
- If the error is occurring while using the Cap Frame Hoop, check the
wires mounted on the driver for tension. If the black bar on the driver
is too loose it can cause distortion. The cables can be replaced if they
are too long. Call your distributor for more information.
- There may be damaged bearings in the Pantograph or Y Carriages. The X
or Y Motors could be damaged. Call your distributor for more information
or a service call.
- Make sure that the thread tension in between the Tensioners, and the
Bobbin Case aren't too tight.
NO JUMP STITCH:
There are running stitches in between letters or objects in the
design. The machine sews back to origin with running stitches at the end of
a design, instead of one long stitch. The needle stays down at the end of a
design. There is a crease down the center of large letters instead of a nice
smooth column.
- The Jump Stitch Solenoid and or the Color Change PCB are damaged. Turn
the machine off. Remove the Saddle Bag Assembly to see the Color Change
PCB. A Digital Volt Meter will be needed to test the resistance of the
Jump Stitch Solenoid at the connector on the left side of the Color
Change PCB.
- The connector will have 2 white wires. Disconnect the connector, and
test the across the 2 white wires. The meter should read 31 ohms if the
solenoid is good. If it reads near 0, call your distributor to order a
Jump Stitch Solenoid (PN#001801-01), and a Color Change PCB (PN#
004125-01). Order the solenoid with a black connector as this solenoid
is used for several types of machines.
- If the resistance tests at 31 ohms, call to replace just the Color
Change PCB. To test the Jump Stitch, just sew a 5 inch Block- I. The
vertical column should be smooth with no creases down the center of the
column.
THREAD BREAKS:
- Check the Needle Depth & Hook Timing first. See the Operator's
Manual on pages 3-19 through 3-23, for information on how to check &
adjust the two settings.
- Replace the current needle(s) as the tips of them will flatten out
after normal use. Sometimes there are burrs that form in the eye of the
needle due to extended use. Try to replace them on a regular basis. Try
once a week, if sewing eight hours a day.
- If the cone of thread that is being used is old or has been sitting on
the shelf for a long time it will be dry and brittle. If the cone must
be used, try spraying it with a pure silicone spray. The thread may
however still break. Replace the cone.
- Check the threading of the cone(s) all of the way to the eye of the
needle, and presser foot to make sure the thread is inside of all thread
guides.
- Check all thread guides for burrs or scratches. Use a piece of thread
to rub around inside of the thread guides to see if it catches on
anything such as a burr. Try using some emery cloth to smooth out burrs.
If the burrs are too deep, replace the thread guide.
- Check the Hook Assembly for burrs, and smooth it out if possible or
replace it. Call your distributor for the part.
- Check the Hook Support (Restraining Finger), for burrs. Try smoothing
them out with emery paper. If burrs are too deep replace the part. Make
sure it is positioned correctly. See pages 3-23 in the Operator's
Manual.
- Make sure the hook assembly is clean of excess thread and fuzz.
- Oil the hook every 4 actual hours of sewing. See page 3-4 of the
Operator's Manual.
- Check thread tensions to make sure they aren't too tight. If the
tensioner wheel moves in a jerky movement, loosen the knob, and check
the threading. Replace the felt pads under, and on top of the tensioner
wheel(s). (PN# 005198-01).
- Check the Presser Foot Height. The Bottom ring of the Presser Foot
should be touching the cloth. If the Presser Foot is hitting too hard,
check the rubber dampers inside the bottom of the Needle Case by
removing the white cover. Replace the dampers if they are damaged. Call
your distributor for parts.
- Check the Needle Plate Hole for burrs on top, and underneath the hole
for BOBBIN DETECT circuit damage.
- Check the Needle Plate Hole centering. Make sure that the needle
passes through the center the hole using a new needle.
- Check the Take Up Lever that is engaged to see if by picking up and
down on it, that it travels up and down more than 1/8 inch. If it does
there may be some teeth missing off of the Take Up Lever Drive Gear or
the individual Take Up Lever itself, or they may just be worn
- The other possibility is that the two gears aren't meshing enough. If
either of these errors are evident, call your distributor, as the
meshing of the gears should be performed by a trained technician.
- Needle breaks and Bird Nesting can cause the Hook Timing to be off.
Check the Hook Timing. If it needs adjustment see pages 3-19 through
3-23 in the Operator's Manual.
- Hitting a hoop may cause the Needle Depth to be incorrect. Make sure
that 1/2 to 3/4 of the eye of the needle shows inside of the hook. It
isn't recommended to use the Needle Gauge that was first supplied with
the machine.
- IMPORTANT: If sewing small lettering size .50 down to .25 in
height, make sure the density isn't too high. The default in EDS is 4.2.
This is 60 stitches per inch. At this density, there would be at least 3
needle strikes in the same hole in order to accommodate the 4.2 density.
- If a design is dense in stitches the same error may happen. This
happens especially if the operator has reduced a design in size.
- If the design is an Expanded Design, the stitch density can't be
reduced. See your EDS Manual for information about design density. Try
slowing the sewing speed down to 500 or 550 to see if the design can be
sewn. It may be a good idea anyway to slow the sewing speed down, due to
the intricacy of the design.
- The size of the eye of the needle can make a difference also. If the
thread is breaking too often, try using a larger eyed needle.
- For instance: If a 70/10 size needle is being used, switch to a 75/11
or 80/12 to accommodate the thread, and the density of the design.
- Make sure thread tensions aren't too tight. Check the Front six
tensioners, and the Bobbin Case. If the Bobbin Tension keeps varying, it
can cause sewing quality and thread break problems. Replace the Bobbin
Case. See the Parts Manual for the part number, and call your
distributor for a replacement Bobbin Case.
- Use adequate backing . An Inadequate amount of backing may allow part
of the garment to be pulled down into the Needle Plate Hole, and cause a
thread break. For instance: Don't use one piece of Tear Away backing to
sew a Sweat Shirt. Use at least 2 pieces of Cut Away Backing so the
cloth will be more stable.
FALSE THREAD BREAKS:
- Check the threading of the tensioner. Check the Take up spring to see
if it's broken. Call distributor if it persists.
LOOPING & BIRD NESTING:
- Looping can be caused by thread tensions that are too loose. This can
be caused by the Main Tensioners, and by the Bobbin Case. Looping can be
on top or underneath the garment. Try turning the front six tensioner
knobs 1 or 2 turns at a time to see if the problem will go away.
- The looping may vary as are result of the knobs being too loose on the
threaded tensioner post. If the knob moves too easily. remove the knob
by unscrewing it. Spread the threaded post slightly with a large slotted
screwdriver. This causes the threads of the post to better match the
threads of the tensioner knob so they don't move so easily. If the
problem persists, call your distributor.
- If the Bobbin Tension changes too often, or won't tighten, replace it.
Call your distributor to order one.
- The density of the design may affect this error also. If the design
density is too tight, the needle and thread will have a hard time
fitting through the hole the needle has to make. See your EDS Manual for
information on Design Density. The density when sewing lettering can
affect this error.
- If sewing small lettering, the 4.2 default is too high for lettering
ranging from .50 down to .25 letter height. The 4.2 density is 60
stitches per inch. If using a Premier Keyboard for the controller, see
pages 3-2 & 3-3 of the Premier Manual.
- The size of the eye of the needle can affect this problem. If the
density of the design is high or the cloth is to elastic, change up to a
larger eyed needle. For instance: If the needle currently being used is
a 70/10 size needle, switch to a 75/11 or even a 80/12 size needle. This
larger eyed needle will allow for smoother passage of the thread through
the eye of the needle. Most thread being used is 40 gauge. If 30 gauge
thread is being used, a larger eyed needle is required. Try an 80/12
size needle. When Metallic thread is being used, at least a 80/12 size
needle should. If your garment permits, it is recommended to use a 90/14
size needle.
- Make sure the Hook Support (Restraining Finger) isn't to close to the
back of the indentation in the Hook Assembly. There should be some space
in between the front of the tab on the finger and the back of the
indentation. See page 3-23 of the Operator's Manual for information
about the placement.
CAP FRAME IN:
- This error will show if trying to SET HOME with the Cap Frame Driver
mounted on the machine.
- If the Cap Frame driver isn't mounted on the machine, the Micro Switch
in the Cap Frame Mounting Block is damaged. Replace it with (PN#
282911-01)
THE CAP FRAME IS POPPING OFF OF THE CAP FRAME DRIVER OR THE DESIGN IS
BEING FLATTENED OUT NEAR AN EDGE OF THE CAP FRAME SEWING FIELD:
- Make sure the Cap Frame Driver Shaft is pushed in so the metal ring
touches the Black Mounting Block. Check the shaft by pulling on it to
make sure it won't pull out during sewing. Don't over tighten the thumb
screw under the Driver Shaft Mounting Block as the threads of the block
can be stripped through over tightening.
- From the surface of the back collar that touches the Driver Block to
the end of the shaft should be 1 7/8 inches.
- Loosen the set screw ,and match this measurement if incorrect. Use a
drop of Red Loctite (Loctite 222) on the threads of the set screw.
- The front surface of the front collar should be flush with the end of
the shaft. If the collar settings are incorrect on either end, the
sewing field "Mechanically", won't match the sewing field
according to the limits set up by the software.
- Check the cables attached to the Cap Frame Driver. They may be too
loose. If the black bar on the driver can be picked up off of the arc of
the driver, out of the groove it rides in, the cables can be too loose.
There are two Cap Head Allen Screws at each end of the bar. Loosen only
two at one end of the bar. Pull the block at the end of the bar towards
the out side of the bar. Be careful not to bow the bar, as it would be
too tight then. If the cables can't be tightened any further, replace
the cables with (PN# 402913-01).
- If the Driver seems to be in good shape, check the Needle Plate to see
if the Cap Frame has been causing any wear marks on the edges. If so,
turn the machine off. Have only the Cap Frame Driver mounted on the
pantograph. Pull the black pantograph bar forward until the front arc of
the Cap Frame Driver is just over the back two edges of the Needle
Plate.
- Center the driver in accordance with left & right. Check to see if
the front arc of the driver touches either the left or right of the
Needle Plate. If it does the Driver may be warped or the cables may be
too loose.
- If there is another Driver present check it in the same manner. If it
clears by at least 1/16 of an inch it is correct. Call your distributor
if a warped Cap Frame Driver is suspected. There may also be a problem
with the Cap Frame Driver Mounting Block. This will also require
information from your distributor.
- Make sure the Mounting Wheels on the Cap Frame Driver are not loose or
damaged. Replace if damaged.
- Check the Cap Frame for bends in it other than normal. Call your
distributor to order parts for the Cap Frame or Cap Frame Driver.
- Check the X Carriage on the pantograph to see if it has too much play
in the rollers. Use the information from the X and Y sections of this
guide.
TRIMMER SECTION
TRIMMER NOT HOME:
This error has to do with weather the movable knife went home or not.
It is located under the Needle Plate.
- Remove the needle plate to see if there is thread that was trimmed
laying inside or jammed under the Fixed Knife. See Figure 2-6a on page
2-10 of the EMC6 (With Melco Head) Technical Manual (PN# 110041-01) to
identify the trimmer parts. Bird Nesting under the needle plate may also
cause the error.
- Check the Under Thread Presser as seen in Figure 2-10 on pages 2-14 in
the Technical Manual to find out what it should look like damaged or
undamaged. If the profile of the part is like the damaged one, call your
distributor to order the part (PN#003119-01).
- Check the Fixed Blade Pressure as seen on pages 2-9 through 2-12 in
the Technical Manual to see how to properly set the blade pressure as to
much pressure can stop the blade from going to the home position
- Check the "Home Position" of the Movable Knife as seen in
figure 2-11 on page 2-14 in the Technical Manual. The procedure for
adjusting the Home Position has changed slightly. Call your distributor
for more information.
- The Cam Follower may be sticking inside the Cam after activation. Call
your distributor if a Z Time out occurs along with the Trimmer Not Home
Error, as the Cam Follower may in fact be sticking in the cam when it
should be out. The Trimmer Assembly maybe damaged.
- The error may be cause by an electronic problem. The Home Position
sensor for the Movable Knife may be damaged. The XYZ Interface may be
damaged at the Trimmer circuit. Remove the needle plate. Try a Trim
Immediate in the Trim Menu to see if any part of the Trimmer System does
not activate. Watch the Movable Knife, Grabber, or Picker. The Trim
Immediate may have to be performed several times to see if any of these
parts don't activate. Call your distributor to replace the XYZ Interface
Bd. (PN# 003663-01), if Trimmer System never activates. For more
information, call your distributor.
THE TRIMMER SYSTEM ACTIVATES, BUT ISN'T TRIMMING THE THREAD:
Grabber Not Home may also be associated with this error if the thread
isn't being cut.
- Check all of the before mentioned information having to do with the
Trimmer System first.
- Another possibility for the error is that the Picker is not timed or
tuned correctly anymore. See pages 2-17 through 2-18 in the Technical
Manual to see how to do so. Thread may wrap around the Picker holding it
in, causing a Z Time out Error also, as the built up thread will stop
the Hook from rotating. Again the Picker Timing is probably out of tune.
- Make sure that the thread tension isn't too loose at the Main
Tensioner or Bobbin Case. Too loose of tension will not facilitate a
good clean trim. Try starting with the pre-tensioner set so that the top
of the split screw inside pre-tensioner knob is flush with the top of
the knob. This can also cause long tails after a trim.
SOMETIMES THE MACHINE WILL LEAVE TOO SHORT OF A TAIL AT THE END OF A
TRIM:
- Check the Main Tensioner & Bobbin Case tensions set so they aren't
too tight. If the thread tensions are too tight, it can cause a
sling-shot affect so the tail is too short, and the thread will pull
right out of the Grabber & Needle Eye when it starts to sew again.
The Main Tensioner Wheel can't turn when the needle comes down to sew
after the trim due to the tightness of the thread tension. Replacing a
Bobbin Case may help stop this error also.
- If the Picker is not tuned correctly, it can let go of the thread
before it is supposed to. Use the Picker Tuning section in the Technical
Manual to fix this problem.
- If the thread trim is frayed after a cut the thread may be being
pulled apart. The Fixed Blade Pressure may need to be adjusted. See
pages 2-9 through 2-12 in the Technical Manual (PN# 110041-01). It may
be necessary to replace the Fixed Blade (PN# 003120-01)
- Select Timing may be incorrect. This is where the Trimmer Assembly is
tuned to the Z Axis or rotation of the Main Head Shaft. This timing
should be performed by a trained technician. If the none of the possible
fixes listed in the trimmer section fix the trimmer errors the machine
has call your distributor for a service call.
GRABBER NOT HOME:
This is where the Grabber did not fully retract in order to activate
the Grabber Home switch.
- As mentioned in the first part of the Trimmer Section, if the top
thread wasn't cut, the grabber blade can't retract to it's home
position. The thread has to be cut to do so. if the thread isn't cut,
use the trimmer section of this guide to try to determine the reason why
it didn't.
- If the actuator screw that is supposed to enable the Home Position
Switch isn't touching the switch arm, and the blade appears to be in the
fully retracted position, then the actuator screw may need to be
adjusted so it does touch the switch arm with enough pressure to do so.
- To find the switch, remove the upside down triangular cover at the
back left side of the sewing head by removing the 2 screws to the cover
to be able to see the Grabber Motor Assembly. If it is still unclear as
to how to adjust the actuator screw, call your distributor for more
information.
- The Grabber Blade may be out too far at a trim or in too far. This
will not necessarily cause a Grabber Not Home Error, but it may stop it
from picking up the thread after a trim. See pages 2-19 through 2-20 in
the Technical Manual to see how the blade is to be adjusted.
