APTC Unit Mount Position Adjustment

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
decrease the backlash (allow less movement of Gear B). Lightly tighten the APTC Securing Screws to
temporarily secure the position of the APTC Unit.
3. Hold Gear C immobile with your finger, and slowly rotate Gear B back and forth. If the APTC Unit Mount Position
is correct ((approximately 0.03 - 0.07mm of backlash), tighten the two APTC Securing Screws that secure the
APTC Unit. If the backlash is not correct, repeat Steps 2 and 3 until the backlash is correct.
