M The drum surface potential of the main charger center
bias measured by the sensor is displayed.
* The normal range of this code is "400 to 800" after
performing 05-2188.
M The value of the main charger grid bias measured with
the drum surface potential sensor is displayed.
* The normal range of this code is "400 to 800" after
performing 05-2188.
M The value of the main charger grid bias measured with
the drum surface potential sensor is displayed.
* The normal range of this code is "400 to 800" after
performing 05-2188.
M The measured value of the residual voltage after
discharging is displayed.
* The normal range of this code is "400 to 800" after
performing 05-2188.
M When a service call has occurred or a warning
message (IQC/SPC) has appeared, "Image quality
control enforcement (05-2120)" should be performed
after the equipment is repaired or the cause of the error
is evaluated. In case the service call occurred or the
warning message (IQC/SPC) appeared again after the
performance of the code 05-2120, a test chart can be
printed out by temporarily using this code (05-2188) if
an image check is urgently needed.
M The humidity of the inside of the equipment is
displayed.[Unit: RH%]
M The temperature of the inside of the equipment is
displayed.[Unit: °C]
M A drum surface temperature detected at the drum
surface potential sensor control is displayed.
M A relative humidity detected at the image quality closed-
loop control is displayed.
