Error Name/Error Condition/Major Cause/Solution
An interrupt checks the status of the power pack every 10 ms. This SC is
issued if a problem exists with 50 consecutive samplings (500 ms).
Details:
SC issued when the image transfer power pack output current is leaking.
The IOB checks for SC signals as described above.
• Image transfer power pack output current is leaking.
Remove the high voltage cable from the output terminal of the image
transfer power pack and check the following items.
• PWM signal check
If signal is fixed during image transfer, replace the cable or the IOB.
• Image transfer power pack output check
If output is fixed during image transfer, replace the power pack.
If output is normal during image transfer, replace the high voltage
cable, ITB or the transfer roller.
Error Name/Error Condition/Major Cause/Solution
Image Transfer Power Pack Error (low output) (K)
Image Transfer Power Pack Error (low output) (C)
Image Transfer Power Pack Error (low output) (M)
Image Transfer Power Pack Error (low output) (Y)
The transfer roller resistance level was "R-3" (detected voltage was lower
than 0.1kV).
• Image transfer power pack defective
• Problem with input harness to the image transfer power pack (loose
connection, harness broken, or connector disconnected).
• Fix or replace the image transfer power pack.
• Check the input harness and connector of the image transfer power
pack.
