Duplex Wait Sensor On - Xerox DocuColor 2240 Service Manual

10-125 Duplex Wait Sensor On

Paper did not arrive at the Duplex Wait Sensor within the specified period of time.
Initial Actions
• Check condition and specification of the paper supply.
• Check the paper path for obstructions.
• Check for wear and clean the Duplex Transport Roll.
• Check for wear and clean the Pinch Rolls.
Procedure
The jam associated with this fault is accompanied by a grinding or rattling sound from
the upper left rear.

• If the problem persists, replace the MCU PWB
There is an alignment problem between the Inverter Transport
(PL 2.11). This can be caused by damage to the Rear Latch or the Reversing Gear Tab in the
Exit Transport (refer to Figure
(which engages the Reversing Gear Tab).
Examine the Exit Transport for damage to Rear Latch or the Reversing Gear Tab. Repair or
replace as required (PL 2.11).
If the Exit Transport appears to be OK, check the Inverter Transport for damage. Repair or
replace as required (PL 11.1).
