Diagnostic Information 2-16
4049-XXX
the LVPS voltages are correct. Turn the power back off and, one at a
time, reconnect the engine board cables, powering on in between
each connection and checking the voltages. The connection which
causes the voltages to be wrong indicates which component is bad.
Repair or replace the failing component or cable as necessary.
Duplex
The duplex unit should home — the front shafts should turn and the
input deflector should move — immediately when you install the
duplex unit with the printer already powered on, or just before the
[Ready] screen is displayed when you POR the printer with the
duplex unit installed. This means the duplex unit and the printer are
communicating and thus the printer engine board, duplex unit sys-
tem board, and the cables between them are all good.
If the duplex unit does not home immediately but homes after 5 or 6
seconds, the duplex unit is rec34 VDC from the printer but is
not communicating with the printer. The duplex unit homes on its
own as a signal that it is functional.
If the duplex unit does not home at all, it is either damaged or is not
rec34 VDC from the printer.
To check the connection from the printer engine board to the duplex
system board, remove the printer RIP Board. Remove the duplex top
cover and table cover, and reinstall the duplex unit. Engine board J3-
2 should have continuity with the duplex system board J5-1, J3-3
with J5-2, and so on. With power on, you should have the following
voltages:
Connector
Voltage to Ground
Engine Board
J3-3
+34 VDC
J3-5
+5 VDC
J3-7
+5 VDC
Duplex System
Board
J5-2
+34 VDC
J5-4
+5 VDC
J5-6
+5 VDC
