2.7.5.4 ADC Solenoid Operation

The ADC Solenoid turns on/off (ON: 0.5 sec/OFF: 0.5 sec) twice
(nominal) every 300 counts (nominal). This operation causes the
Cleaning Lever to clean the ADC Sensor emitter/receptor.
NOTE: The count described above is based on the following:
1 count:
Printing a sheet that has a length (feed direction) of
219mm (LETTER/LEF) or smaller
2 counts:
Printing a sheet that is larger than the above.

During these sequences, the following errors are detected.
• Toner out
• ADC sensor error
• Abnormal density (too low) error
• Abnormal density (to high) error
• PCDC error
The printer indicates the corresponding message on the LCD panel and
stops printing.
