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.
