2-118 Service Manual
5060-4xx
Finisher is inoperative, or not recognized
This problem can be caused by a problem with the autoconnect system between the finisher and the printer. It
also can be caused by a problem with the power system in the finisher.
Step Action and questions Yes No
1 Check the AC line cord to the finisher to make sure the
options and printer are connected properly.
Are the printer and options AC line cords connected
properly?
Go to step 2 Connect the
printer and
options correctly
2
Make sure the communications cable from the finisher
to the printer is installed correctly at the output options
autoconnect on the printer.
Is the cable installed correctly?
Go to step 3 Install the cable
correctly
3
Disconnect the autoconnect cable from J2 on the
system board. Check the resistance between J2-6 and
J2-7 on the cable connector. The resistance measures
between 45 ohms and 50 ohms.
Is the resistance correct?
Go to step 6 Go to step 4
4
Make sure the communications cable is connected
properly to CN3 on the LVPS relay board.
Is the cable installed correctly?
Note: The relay on the relay board is connected to
+5 V dc from the printer through the communications
cable. When the printer is powered on, +5 V dc is sent
to the finisher relay board relay coil which energizes
the relay and connects primary AC line voltage to the
LVPS.
Go to step 5 Install the cable
correctly
5
Check the resistance of the relay coil by measuring
between CN3-1 and CN3-2 on the relay board. The
resistance measures between 45 ohms and 50 ohms.
Is the resistance correct?
Replace the
communication
cable
Replace the relay
board/LVPS
assembly
6
Check the voltage on the output options autoconnect
connector Pin 2 located on the top right rear of the
printer. The voltage measures approximately +5 V dc.
Is the voltage correct?
Go to step 7 Go to step 10
7
Check the AC line voltage between CN2-1 and CN2-3
on the relay board. The line voltage should be within
specifications for the AC power source the printer is
connected to.
Is there line voltage at CN2?
Replace the
LVPS assembly
Go to step 8
8
Check the AC line voltage between CN1-1 and CN1-5
on the relay board. The line voltage should be within
specifications for the AC power source the printer is
connected to.
Is there line voltage at CN1?
Replace the relay
board assembly
Go to step 9
9
Check continuity of the AC line cord.
Is there continuity?
Go to step 10 Replace the line
cord
