Sorter Bin Jam Rap - Xerox Phaser 790 Service Manual

011-701 Sorter Bin Jam RAP

Sorter Control PWB logic did not detect paper at the Sorter Path Sensor within 600 ms (the
same amount of time allowed for the bins to move one level) after the last sheet has left the
Sorter Path Sensor.
Initial Actions
Check the Sorter Transport Motor Belt for damage and correct tension. Also check the Bin
Drive Motor Assembly for broken or worn gears.
Procedure
NOTE: Prior to replacing a component, unplug the connectors to the components (Bin Cam
Switch and Bin Drive Motor). Check the connectors for broken, bent and dirty pins. Unplug and
plug-in the connectors several times to remove contaminants due to oxidation. The resistance
created by the contaminants will change the Machine Timing (measured in ms) which is inca-
pable of being observed with a multi meter.
Observe the Sorter Bins during power up and initialization of the Sorter. The Sorter Bins ini-
tialize correctly.
Y N
Remove the Front and Rear Covers from the Sorter. Remove the two screws on the Bin
Home Switch from under the Bin Assembly so as to be able to actuate and deactuate the
switch. Measure the voltage between J 4-3 (+) of the Sorter Control PWB and GND (-).
Actuate and deactuate the switch. The meter changes state from a Low (0 VDC) to a
High (+5 VDC).
Y N
The voltage remains Low (0 VDC).
Y N
Go to Flag 2 and check the harness for an open circuit. If the harness is OK,
replace the Bin Home Switch (PL 19.4).
There is +5 VDC between J 8-10 (+) and GND (-).
Y N
Refer to the +5 VDC wirenet and check the wires for an open circuit to the
Sorter Control PWB.
Go to Flag 2 and check the harness for an short circuit. If the harness is OK, replace
the Bin Home Switch (PL 19.4). If the problem persists, replace the Sorter Control
PWB (PL 19.1).
The Bin Home Switch appears to be working normally. Check the Bins for proper align-
ment. If the problem continues, replace the Sorter Control PWB (PL 19.1).
Remove the Front and Rear Covers from the Sorter. Remove the two screws on the Bin Cam
Switch from under the Bin Cam Assembly so as to be able to actuate and deactuate the switch.
Measure the voltage between J 4-1 (+) of the Sorter Control PWB and GND (-). Actuate and
deactuate the switch. The meter changes state from a Low (0 VDC) to a High (+5 VDC).
Y N
The voltage remains Low (0 VDC).

Go to Flag 1 and check the harness for an open circuit. If the harness is OK, replace
the Bin Cam Switch (PL 19.4).
There is +5 VDC between J 8-10 and GND (-).
Y N
Refer to the +5 VDC wirenet and check the wires for an open circuit to the Sorter
Control PWB.
Go to Flag 1 and check the wires for a short circuit. If the harness is OK, replace the Bin
Cam Switch (PL 19.4). If the problem persists, replace the Sorter Control PWB (PL 19.1).
Reinstall the Bin Cam Switch. Access the Digital Output (DO) test from the Control Panel.
Enter code [C6]. Press the Item/Enter button. The Bin Drive Motor energizes and the Bins
move up one (1) Bin.
Y N
There is +24 VDC between J9-3 (+) on the Sorter Control PWB and GND (-).
Y N
Go to 011-702 Sorter Cover Open RAP.
Go to Flag 3 and check the wire for an open circuit. If OK, replace the Bin Drive Motor (PL
19.4).
Enter [Stop DO Test] from the Control Panel. Enter code [C6]. Press the Item/Enter button.
Access the Digital Output (DO) test from the Control Panel. Enter code [C5]. Press the Item/
Enter button. The Bin Drive Motor energizes and the Bins move down one (1) Bin.
Y N
There is +24 VDC between J 9-3 (+) on the Sorter Control PWB and GND (-).
Y N
Go to 011-702 Sorter Open RAP.
Go to Flag 4 and check the wire for an open circuit. If OK, replace the Bin Drive Motor (PL
19.4).
Enter [Stop DO Test] from the Control Panel. Enter code [C5]. Press the Item/Enter button.
Place a piece of paper in Bin 1. Access the Digital Output (DO) test from the Control Panel.
Enter code [D6]. Press the Item/Enter button. The Display is 1.
Y N
There is +5 VDC between J 10-4 of the Sorter Control PWB and GND.
Y N
Go to Flag 5. Check for a short circuit to ground. The wire is good.
Y N
Repair the wire.
There is +5 VDC between J 5-1 of the Sorter Control PWB and GND.
Y N
Go to Flag 6. Check for an open circuit or a short circuit to ground. The
is good.
Y N
Repair the wire.
Replace the Sensor Receiver (PL 19.2).
