[PC SelfChk] Process Control Self-checks
1 Job End *BCU Specifies the execution timing of the job end
process control self-check.
[ 0 to 999 / 200
/ 1 print/step ]
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.
2 Interrupt *BCU Specifies the execution timing of the interrupt
process control self-check.
[ 0 to 999 / 0
/ 1 print/step ]
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.

process control self-check.
[ 0 to 999 / 0
/ 1 print/step ]
0: Disable
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.
