St Btr Contact - Xerox DocuColor 2240 Service Manual

9-348 1st BTR Contact

The 1st BTR did not reach the contact position.
Initial Actions
• Clean the 1st BTR Retract Sensor (PL
• Check the 1st BTR Worm Gear and Retract Shaft
Procedure
In sequence, enter the following: dC330 [009-054] then dC330 [009-055]. The 1st BTR con-
tacts and retracts.
Y N
There is +24VDC from P/J533-A16 on the I/F PWB to GND
Y N
Go to the +24 VDC Wirenets (Figure

Check the wires between P/J533
opens, shorts, or loose connections. If the wires are OK, replace the 1st BTR Retract
Motor (PL 5.4). If the problem continues, replace the MCU PWB
