CLOSE MIDDLE FRONT DRAWER
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 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.
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.
