5.2.2 Backlash Adjsutment

This section describes Backlash Adjsutment that is to be made after
removing the PF motor. This adjustment provides an appropriate
=
backlash ( 0.1 mm or less) for PF motor pinion gear and the gear (76).
You need to make this adjustment when you replace any of the following
parts:
PF motor assembly
Gear 76
PF roller unit
Failure in making this adjustment causes the printer to
C A U T I O N
operate abnormally as described below:
If backlash is too little:
1. The PF motor dose not rotate correctly and paper
feeding accuracy declines.
2. Gear 76 and the PF pinion gear make abnormal
noises during printing.
If backlash is too large, the PF motor dose not rotate
correctly and paper feeding accuracy declines.
