Ibt Home Sensor - Xerox DocuColor 2240 Service Manual

9-350 IBT Home Sensor

The IBT Home Sensor detected the IBT position strip before the IBT Belt made a complete rev-
olution.
Initial Actions
• Ensure that the Transfer Belt is installed correctly.
• Clean the IBT Home Sensor (PL 5.4) and check for damage
• Check the IBT drives for damage (PL
Procedure
Remove the IBT Assembly. Enter dC330 [004-002]. The IBT Motor operates.
Y N
There is +24VDC from P/J551-3 on the I/F PWB to GND
Y N
Go to the +24 VDC Wirenets (Figure
Check the wires between P/J551 and the IBT Motor
connections. If the wires are OK, replace the IBT Motor
replace the MCU PWB (PL 13.1). If the problem continues, replace the I/F PWB
Enter dC330 [004-014]. There is +5VDC from P/J533-A9 to A12 on the I/F PWB
Y N
Go to Figure 2 and check the wire from P/J533-A9 to
short circuit. If the wire is OK, replace the MCU PWB
replace the I/F PWB (PL 9.1).
There is +3.3VDC from P/J533-A13 to A12 on the I/F PWB.
Y N
Go to Figure 2 and check the wire from P/J533-A13 to
short circuit. If the wire is OK, replace the MCU PWB
replace the I/F PWB (PL 9.1).
