10-111 Machine Exit Sensor Off Jam Rap - Xerox DocuColor 12/DCCS50 Service Manual

10-111 Machine Exit Sensor Off Jam RAP

When using either the inversion path or exit path, the Machine Exit Sensor did not deactuate
within the specified time after it actuated.
Initial Actions
Refer to BSD 10.7, 10.9, and 10.12 for the following procedure.
Make ONE single-sided set of 10 or more originals. (This causes the copies to go through the
inversion path and exit the machine face down.) Repeat this job several times. Next, make
TWO single-sided sets of 10 or more originals. (This causes the copies to bypass the inversion
path and exit the machine face up.) Repeat this job several times. If a fault occurs ONLY when
the copies exit the machine face down, replace the Exit Roll Assembly
with Tag 23 install the Tag 23 Exit Roll Assembly, machines with an Offset Catch Tray install
the Offset Roller Kit, machines without an Offset Catch Tray install the Corrugation Mark Roller
Kit. If the fault occurs when the copies exit the machine face down AND face up, continue with
Initial Actions below:
Check for the following:
• Obstructions in the inverter and exit paper path
• Equal Pinch-roll (PL 2.25) force at the Machine Exit Roll
• Binding of the Machine Exit Roll (PL
• Ensure that the Inverter Pinch Rolls (PL
• Remove the Inverter Door Cover (PL
vent jamming. Look for skew along the lead edge of the paper as it inverts and exits the
machine. If skewing occurs, check for movement in the Door Latch area by pressing on
the door. If the door moves in, hold it closed at the latch area to see if feeding improves. If
feeding improves, check the (door) Lever (assembly)
components. To minimize movement in the Inverter 2 Assembly, loosen the two screws
holding the white plastic latch and metal latch bracket. Move both parts to the right and
then tighten the screws.
• Clean the Machine Exit and Inverter Rolls
• Ensure that connectors P/J412B, P/J418B
Drive PWB and the Machine Exit Sensor, and there are no obvious crimped or broken
wires.
Procedure
Enter dC330 010-110 Machine Exit Sensor. Press Start. Actuate the Machine Exit Sensor
actuator. The display changes from L to H.
Y N
The display is a constant H.

Go to Flag 7 on BSD 10.7 and check the harness for an short circuit. If the harness is
good, replace the Machine Exit Sensor
Connect the meter from P/J412B-5 on the IOT PWB to GND. Actuate the Machine Exit
Sensor actuator. The voltage at P/J412B-5 goes from less than +1.0 VDC when the
sensor is deactuated, to +5 VDC when the sensor is actuated.

Press Stop. Approximately +7 VDC is measured between P/J418B-17 on the IOT
Drive PWB and GND.

Go to Flag 2 on BSD 10.9 and check the harness for an open circuit. If the harness is
good, replace the Exit Motor
PWB (PL 9.2).
Check for binding, obvious damage, missing and/or broken Drive Motor gear assemblies and
drive belts that would cause the paper to be slow to leave the Machine Exit Sensor. If OK,
replace these components in the following order: Exit Roll (Assembly)
