APTC Unit Mount Position Adjustment
This adjustment is required if you:
• Remove or replace the Carrier Unit
• Remove or replace the APTC Unit
• Remove or replace the APTC HP Unit
• Remove or replace the PJS Roller Assembly
• Remove or replace the PJS Holder Assembly
1. Hold Gear C immobile with your finger, and slowly rotate Gear B back and forth. If the APTC Unit Mount Position
is correct, you will see and feel a very small amount of movement (known as backlash) of Gear B (approximately
0.03 – 0.07mm). If there is either too little or too much movement of Gear B, proceed with the steps below.
2. Verify that the reference pin on the side frame is in the positioning hole of the APTC Unit. Loosen the two APTC
Securing Screws that secure the APTC Unit. Move the APTC Unit towards the front of the printer to increase
the backlash (allow more movement of Gear B). Move the APTC Unit towards the back of the printer to
