Drum Motor - Xerox DocuColor 2240 Service Manual

4-361 Drum Motor

Drum Motor failure.
Initial Actions
• Remove all Drum Cartridges.
• Perform REP 1.6.
Procedure
The machine is a DC3535.
Y N
Enter dC330 [004-003] and press Start. The Drum Motor energizes and the drives
rotate.
Y N
Go to Figure 1 of this procedure and measure voltage between the Drum Motor
J210-4 (+) and GND (-). +5 VDC is measured.
Y N
Go to Figure 3 of the +5 VDC Wirenets and troubleshoot the problem.
Go to Figure 1 of this procedure and measure voltage between the Drum Motor
J210-6 (+) and GND (-). +24 VDC is measured.
Y N
Go to Figure 2 of the +24 VDC Wirenets and troubleshoot the problem.
Enter dC330 [004-003] and press Start. Measure voltage between:
• P/J210-1 (+) and GND (-)
• P/J210-2 (+) and GND (-)
Less than +1 VDC is measured on P/J210-1 and 2.
Y N
Enter dC330 [004-003] and press Start. Measure voltage between:
• P/J535-B5 (+) and GND (-)
• P/J535-B3 (+) and GND (-)
Less than +1 VDC is measured on P/J535-B5 and B3.
Y N
• Check connection between MCU PWB and I/F PWB (P410).
• If no problems are found, replace the MCU PWB
• If the problem persists, replace the I/F PWB
• Check for wire damage or bad connection between
• If no problems are found, replace the Drum Motor
Enter dC330 [004-003] and press Start. Measure AC and DC voltage between
J210-3 (+) and GND(-).
NOTE: If you can measure frequency (Hz) with your meter, then you may check for 1
- 1.3 KHz on P/J210-3.
2.5V AC and DC is measured (1 - 1.3 KHz is measured.)
Y N
Enter dC330 [004-003] and press Start. Measure AC and DC voltage between
I/F PWB P/J535-B2 (+) and GND (-).
