8 Chapter 1 Troubleshooting control panel messages
EN
The drawer that holds the imaging drum is open. Switch SW3 indicates
that the drawer is open. When the drawer is closed a plastic protrusion
on the lower left corner of the drawer pivots an arm that allows SW3 to
toggle to the open position.
Note
Closing the drawer also closes SW4 (the front drawer switch). When
SW4 is open +24B Vdc is disabled. This safety feature protects the
operator from any high voltages when the upper or middle front
drawers are open.
1 Open the drawer and firmly push the drawer closed using one hand
in the middle of the drawer.
2 If the message persists, remove the printer’s left-side cover and
inspect the mechanical linkage that closes SW3.
3 Refer to the wiring diagram (chapter 10) and verify the wiring; the
two-wire connector should be firmly seated to SW3 and the wiring
harness should be firmly seated to connector J1003 of the DC
controller PCB.
4 If message persists, use an ohmmeter to verify the functionality of
SW3.
