092-315, 332, 660, 668 ATC Sensor Fault RAP
BSD-ON:
092-315 Toner density in the developer unit as detected by the ATC sensor is abnormal. This
fault occurs when the difference between the maximum and minimum values in the ATC sen-
sor measurement set is lower than the threshold value.
092-332 ATC test warning.
PL 90.20 Item 1.
092-660 Toner density in the developer unit as detected by the ATC sensor is abnormal. This
fault occurs when the difference between the maximum and minimum values in the ATC sen-
sor measurement set is lower than the threshold value.
092-668 Toner density in the developer unit as detected by the ATC sensor is abnormal. this
fault occurs when the average value of the ATC sensor measurement values is not between
the upper and lower limit values.
Procedure
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
death or injury. Moving parts can cause injury.
NOTE: When this fault occurs, toner density control, by the ATC sensor, is not performed and
ICDC (pixels) based toner supply control is performed instead. If the fault remains for a long
time, image density error (too dark or too light) may occur.
Refer to the procedure that follows as necessary:
