Dew condensation might have occurred in the machine. (The temperature/humidity sensor on
the high voltage control PCB detects sudden environmental change.) / High-voltage power
supply PCB error

- Power off and open the top cover. Wait 30 minutes, and then turn it ON again after closing
the top cover.
- Clean the corona wire in the drum unit.
- Replace the drum unit with a new one.
■ Error code 1B

Error code 1D
Error code 83
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.
<User Check>
- Replace the drum unit of the appropriate color with a new one.
- After replacing the drum unit with a new one, reset the counter using the control panel cover ASSY
on the machine. (Refer to
“2.1.3 Resetting the life counter of the drum unit” in Chapter 7.
)
Print Unable 1A
Turn the power switch off and open the top cover, wait 30 minutes, and then
turn it on again.
Step Cause Remedy
1 Dirt on drum unit electrodes Clean the electrodes of the drum unit and
main body. (Refer to Fig. 3-3 (P3-33) and
Fig. 3-6 (P3-34).)
2 HVPS control PCB failure Replace the HVPS control PCB ASSY.
3 High-voltage power supply PCB
failure
Replace the high-voltage power supply
PCB ASSY.
