Drum error
* After the error code 48, 49, 4A, or 4B (the drum unit is at the end of life) occurs, and when
the counter value exceeds twice the life expectancy and electric discharge occurs due to
smear on the corona wire, and disturbance is detected in the charge current of the
high-voltage power supply PCB, the error code 83, 1B, 1C, or 1D appears. When the error
code 83, 1B, 1C, or 1D appears, the performance of the drum unit cannot be maintained,
and the print quality is deteriorated, and therefore the use of the drum is stopped.
