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.
