4-363 K Drum Motor
Drum Motor K failure
Procedure
BSD: CH9.2CH9.31A
Remove K DRUM. Enter dC330 [004-006] and press Start. Drum Motor K energizes.
Y N
Between Drum Motor K j235-4(+) and GND(-). +5 VDC is measured.
Y N
Following Wire Network, check +5VDC circuit to Drum Motor K j235-4.
Between Drum Motor K j235-2(+) and GND(-). +24 VDC is measured.
Y N
Following Ch7 Wire Network, check +24VDC circuit to Drum Motor K j235-2.
Between Drum Motor K j235-5(+) and GND(-). Ensure dC330 [004-006] is entered and
press Start. 0 VDC is measured.
Y N
Between I/F PWB j534-A11(+) and GND(-). Ensure dC330 [004-006] is entered and
press Start. 0 VDC is measured.
Y N
Check connection between MCU PWB and I/F PWB P410/j410.
If the check is good, replace MCU PWB
If the problem continues, replace I/F PWB
Check wire breakage and bad connection between I/F PWB j534-A11 and Drum
Motor K j235-5
Between Drum Motor K j235-8(+) and GND(-). Ensure dC330 [004-006] is entered and
press Start. Frequency is between 1KHz and 1.3 KHz.
Y N
Between I/F PWB j534-A8 and GND (-). Frequency is between 1KHz and 1.3
KHz.
Y N
Check connection between MCU PWB and I/F PWB p410/j410.
If the check is good, replace MCU PWB
If the problem continues, replace the I/F PWB
Check wire breakage and bad connection between I/F PWB j534-A8 and Drum
Motor K j235-8.
Between I/F PWB j534-A10 and Drum Motor K j235-6
between I/F PWB j534-A9 and Drum Motor K j235-7
If the check is good, replace Drum Motor K
Between I/F PWB j534-A7(+) and GND(-). Enter dC330 [004-006] and press Start.
Y N
Check connector between MCU PWB and I/F PWB p410/j410. If the check is good,
replace MCU PWB (PL 13.1).
If the problem continues, replace the I/F PWB

Between Drum Motor K j235-9(+) and GND(-). Ensure dC330 [004-006] is entered and press
Start. +5 VDC is measured
Y N
Check wire breakage and bad connection between Drum Motor K j235-9 and I/FPWB
j534-A7.
Check if there is load on K DRUM. If the check is good, replace Drum Motor K
