The measurement of the color change housing location is done in reference to the top inside edge of the upper v-rail.
The squareness of the location is the difference between the perpendicular measurement of the distance from the left front and right front edges of the color change housing base to the inside edge of the v-rail.
The location of the color change housing assembly should be no more than 0.010” [0.25mm] out of square (difference between the left- and right-side measurements).
To adjust the location of the color change housing assembly, loosen the screws on the base of the assembly just enough so that you can move the assembly.
Position the assembly to obtain the required squareness and then re-measure the color change housing location. After adjusting the squareness of the color change housing it needs to be checked that the take-up lever drive gear still clears all 16 take-up levers. Should this not be the case the drive gear needs to be readjusted.
When the location is square to less than 0.010” [0.25mm], tighten the mounting screws to Melco Torque Specifications.
