K Drum Motor - Xerox DocuColor 2240 Service Manual

4-363 K Drum Motor

Drum Motor K failure.
Initial Actions
• Remove all Drum Cartridges.
• Perform REP 1.6.
Procedure
The machine is a DC3535.
Y N
Enter dC330 [004-006] and press Start. Drum Motor K energizes.
Y N
Go to Figure 1 of this procedure and measure voltage between I/F PWB P/J534-A12
(+) 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 I/F PWB P/J534-A15
(+) and GND (-). +24 VDC is measured.
Y N
Go to Figure 2 of the +24 VDC Wirenets and troubleshoot the problem.
Enter dC330 [004-006] and press Start. Measure voltage between:
• P/J534-A9 (+) and GND (-)
• P/J534-A10 (+) and GND (-)
• P/J534-A11 (+) and GND (-)
Less than +1 VDC is measured on P/J534-A9,A10 and A11.
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 between
• If no problems are found, replace the Drum Motor
Enter dC330 [004-006] and press Start. Measure AC and DC voltage between P/J534-A8
(+) and GND (-).
NOTE: If you can measure frequency (Hz) with your meter, then you may check for 800 -
900 Hz on P/J534-A8.
Approximately +2.1V AC and DC is measured (800 - 900 Hz is measured).
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
Enter dC330 [004-006] and press Start. Measure voltage between P/J534-A7 (+) and
GND (-). Less than +1 VDC is measured.

Replace Drum Motor (PL 1.1).
• 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
Enter dC330 [004-006] and press Start. Drum Motor K energizes.
Y N
Go to Figure 2 of this procedure and measure voltage between I/F PWB P/J534-A6 (+)
and GND (-). +5 VDC is measured.
Y N
Go to Figure 3 of the +5 VDC Wirenets and troubleshoot the problem.
Go to Figure 2 of this procedure and measure voltage between I/F PWB P/J534-A9 (+)
and GND (-). +24 VDC is measured.
Y N
Go to Figure 2 of the +24 VDC Wirenets and troubleshoot the problem.
Enter dC330 [004-006] and press Start. Measure voltage between:
• P/J534 -A5 (+) and GND (-)
• P/J534 -A4 (+) and GND (-)
• P/J534-A3 (+) and GND (-)
Less than +1 VDC is measured on P/J534-A5,A4 and A3.
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 between
• If no problems are found, replace the Drum Motor
Enter dC330 [004-006] and press Start. Measure AC and DC voltage between P/J534-A2 (+)
and GND (-).
NOTE: If you can measure frequency (Hz) with your meter, then you may check for 800 - 900
Hz on P/J534-A2.
Approximately +2.1V AC and DC is measured (800 - 900 Hz is measured).
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
Enter dC330 [004-006] and press Start. Measure voltage between P/J534-A1 (+) and GND (-
). Less than +1 VDC is measured.
Y N
Replace Drum Motor (PL 1.1).
• Check connection between MCU PWB and I/F PWB (P410).
