• Capping station is clogged.
• The capping station may need cleaning.
• If the print head did not seat properly, all of the nozzles may be clogged. Contact Melco Tech.

• No ink is flowing from the cartridge.
• A vacuum can be created in the ink cartridge. Contact Melco Tech or replace with a new cartridge.

• The ribbon cable to the print head is burnt or not connected.
• This can happen if you replaced a print head and did not ensure that the cable was properly attached.

• Main board is bad.
• There is a chance that the main board is bad or has a defect. Contact Melco Tech.

Possible Causes and Solutions

• Check for the ready message at the printer display.
• There is a connection problem.
• Check the USB connection. Remove the cable and reinsert it.
• There is a communication error between the printer and computer.
• Restart the printer and the computer to ensure that all pending jobs have been deleted.

Possible Solutions

• Use shorter SB cables and avoid switches or hubs with large traffic loads.
• Properly cancel print jobs without leaving jobs in the spooler.

Possible Causes and Solutions

• The print head was damaged by crashing into an obstruction.
• Order a replacement print head and contact Melco Tech.
• The capping station is dirty.
• Thoroughly clean the capping station. This will prevent buildup on the capping station and the print head.
• Too much is  in the cartridges.
• If the cartridges are overfilled, there could be too much pressure in the ink lines and ink could be forced out of the print head. Cartridges should be filled below the maximum ink line.
• Altitude is affecting the ink pressure.
• Higher altitudes can affect the pressure in and around the ink system. If you are experiencing a large amount of issues and are at a higher altitude, fill the ink cartridges with a lesser amount.
• The printer is not level.
• If the printer is not level, the ink system will not be level either. This will also have an effect on the pressure in and around the ink system. Make sure the printer is level.
• Faulty cartridges.
• Change the ink cartridges and contact Melco Tech.
• The dampers are faulty or expired.
• Order replacement dampers and contact Melco Tech.

Possible Solutions

• Always adjust the table height.
• Clean the capping station on a regular basis.
• Clean debris from around the print head on a regular basis.
• Keep the printer level.
• Don't overfill the ink cartridges.

Possible Causes and Solutions

• The capping station is dirty and either not cleaning the print head completely or adding more debris to the print head and causing the print head to become clogged.
• Thoroughly clean the capping station and the wiper blade as described in the daily or weekly maintenance procedures.
• Ink in the nozzle opening has dried out from exposure to air for an extended period.
• Perform head cleans until a decent nozzle check is achieved.
• Perform a powerful cleaning cycle and check for a decent nozzle check.
• A serious or permanent clog of the print head may require replacing the print head. Please contact Melco Tech.
• The print head was damaged by crashing into an obstruction.
• Order a replacement print head and contact Melco Tech.

Possible Solutions

• Perform the daily, weekly, and monthly maintenance procedures as described.
• Perform head cleans and nozzle checks before printing on garments.
• Pretreated fabric must not contact the print head as the pretreatment will react with the print head surface and potentially block nozzles. Should contact occur, clean the print head immediately with alcohol.

Possible Causes and Solutions

• The preparation to print couldn't start correctly.
• This message may appear after the printer has printed the white layer and before the CMYK layer. To bypass, press Shift+F1. The print job does not get lost and the garment is not damaged. It has been noted that if the maintenance tank is over 50% full, this may happen more frequently. To prevent, empty and reset the maintenance tank more often.

Possible Causes and Solutions

1. Immediate stop to the printing - Power OFF the printer.
2. Cancel the printing - Cancel the job and all other pending jobs from the printer spooler in the windows control panel "Printers and Faxes". Ensure on the computer that all print jobs have been deleted.
3. Restart printer.
