CLOSE MIDDLE FRONT DRAWER
Description:
The drawer that holds the intermediate transfer belt is open.
This drawer is called the ITB drawer, but is referred to as the
middle front drawer for end users. Switch SW1 (refer to
Figure 7-31) indicates the drawer is open. When the drawer
is closed, a plastic protrusion on the lower left corner of the
drawer pivots an arm allowing SW1 to toggle to the open
position.
Action:
1. Close the ITB drawer.
2. If the message persists, remove the printer’s left-side
cover and inspect the mechanical linkage that closes
SW1.
3. Refer to the wiring diagram to verify the wiring; the two-
wire connector should be firmly seated to SW1 and the
wiring harness should be firmly seated to connector
J1003 of the DC controller PCB.
4. If the message persists, use an ohmmeter to verify
functionality of SW1.

the rear door pushes a door switch actuator that runs along
the left-side of the printer and closes SW5.
Action:
1. Close the upper rear drawer.
2. If the message persists, remove the printer’s left-side
cover and inspect the mechanical linkage of SW5 and
the lever.
