General Troubleshooting
Paper Size Switch Assembly
Paper size and tray presence is detected by the state of the upper, middle,
and lower switches of the Paper Size Switch. A failed or jammed switch
effects the printer’s ability to accurately detect paper size or the presence of
the paper tray.
Power Supply
LVPS Overcurrent Protection Circuit
This circuit stops all outputs if the 24 VDC, 5 VDC or 3.3 VDC power supply is
shorted. The circuit is reset when the short is removed, the power is turned
off, and then on again.
Note
The 5V supply to the Image Processor Board is excluded. This circuit is
protected by a fuse (F101) which if blown, must be replaced.
LVPS Overvoltage Protection Circuit
This circuit stops all outputs if the 24 VDC, 5 VDC or 3.3 VDC power supply
exceeds the specified voltage. The operating point is 32 VDC or more for 24
VDC, 7 VDC or more for 5 VDC, or 6 VDC or more for 3.3 VDC.
Note
The circuit resets after a short period of time, approximately 5 minutes,
after the printer power is cycled.
Fan Output Circuit
For the Fan Rear On(H) and Fan LVPS On(H) signals, the output voltage
varies depending on the status of FAN LOW signal and FanStop signal from
the Fan Control circuit on the LVPS (refer to “Power” on page 10-17).
