Control panel messages

1
This message occurs if you do not have the intermediate transfer belt
installed in the printer or if the home positions (marks on the ITB) are
not detected by sensor PS5.
Note
The intermediate transfer belt must be rotating before PS5 is able to
detect the “home position” marks on the ITB. Both the ITB and the
imaging drum are driven by the drum motor (M4).
1
Check SW1 for correct operation and make sure the cables are
connected.
2
Verify that the ITB is installed in the printer.
3
If the ITB is installed and seated properly, verify that PS5 is not
damaged. PS5 is located on the ITB assembly. If the sensor
appears damaged, replace the entire ITB assembly.
4
Clean PS5.
5
Verify all wiring within the ITB drawer. Note the connection on the
ITB assembly (located on the front, lower, left-hand corner of the
assembly). When the drawer is closed the connector “mates” with a
receptacle connector on the drawer. Verify that the connector and all
wiring are in good condition.
6
Verify that the drum motor (M4) is rotating both the imaging drum
and the ITB. If necessary use a light felt marker and identify a spot
(outside the imaging area) on the edge of the imaging drum. Turn on
the printer, then open the drawer to see if the mark has moved.
7
If the imaging drum is not rotating, verify that the imaging drum
connector is firmly seated into the J204 connector of the developing
PCB.
