3-905 [M/A Target]
Adjusts the target amount of each toner on paper sheets.
These values are optimized before shipment. Do not change the values. Changing
these values does not affect toner density on paper sheets.

/step] DFU
Displays the amount of each toner on the paper.
A problem may have occurred in the copier engine if the value is high or low (i.e., if
the difference between SP3-905-1/2/3/4 and SP3-5/6/7/8 is larger than
±
0.03

).
Possible problems: Defective TD sensor, defective ID sensor, toner near-end (if the
value is lower than the target), defective toner supply mechanism

3-906 [PC Self Check] Process Control Self-checks
Job End *BCU [ 0 to 999 / 200 / 1 print/step ] 3-906-1
Specifies the execution timing of the job end process control self-check.
The job end process control self-check is automatically done after a job is completed
when 200 prints have been made since the last self-check.
The counter for the job end process control self-check resets when one of the
following process control self-checks is done.
•
Initial
•
Interval: Interrupt
•
Non-use Time
• During Toner End
When K prints are made, the number of prints is calculated with the K coefficient in
SP3-906-5.
Interrupt
*BCU [ 0 to 999 / 0 / 1 print/step ] 3-906-2
Specifies the execution timing of the interrupt process control self-check.
The interrupt process control self-check is automatically done if the number of prints
in the job exceeds the number set in this SP mode. When the print job is completed,
the counter is reset, even if the interrupt self check did not occur.
When K prints are made, the number of prints is calculated with the K coefficient in
SP3-906-5.
Non-use Time 1
*BCU [ 0 to 999 / 0 / 1 print/step ]
0: Disable
3-906-3
Specifies the executing timing of the non-use time process control self-check.
The non-use time process control self-check is automatically done after the number of
prints set with this SP mode have been made and no prints have been made for the
time set with SP mode 3-906-4 since the last print job.
If the conditions are met, the self-check will be done after the print job is completed.
The counter is reset when the initial process control self-checks is done or when a
print is made.
Non-use Time 2
*BCU [ 0 to 2550 / 480 / 10 minutes/step ]
0: Disable
3-906-4
Specifies the executing timing of the non-use time process control self-check.
