Croma24 Service Manual

X-Axis Calibration

The X-axis calibration procedure ensures that the processing that drives the stepper motor is correct to minimize line length accuracy errors.

Pinch Roller Adjustment Procedure

The purpose of the Paper Skew Adjustment is to make certain that the Pinch Roller in the Upper Roller Support stays centered on its shaft and/or has a gap when the Lower Roller is rotated forward for approximately two full revolutions. In other words, the Pinch Roller should not drift rapidly to the left or to the right when the Lower Roller is rotated forward for two full revolutions. (Slow drifting is acceptable.)

Use the torque screwdriver with the P0 bit to adjust the Pinch Roller mounting screws. The maximum torque requirement is 1 in-lbs ± 0.5.
