Total number of pages printed after last process
control execution reaches 200, or reaches 250
*2
*1 Change in ambient conditions
• Temperature has changed by 5°C or more since last job end.
• A change in humidity is compared with an internal lookup table to determine when to trigger
process control.
*2 Total number of pages printed has reached 200 but not yet reached 250:
• Execute at job end
• Execute at 250 pages at page end if the job has not ended
If any of the following conditions exist, toner coverage process control is not performed, regardless of
the result of the events and triggers described above.
• When the waste toner bottle is detected full.
• When the waste toner collection unit inside the Black (K) AIO is detected full.
• When the machine issues toner end for the Black (K) AIO.
If waste toner collection full is detected (or toner end detected) in at least one of the color AIOs (C, M,
Y), and the Black (K) AIO is not at toner end, the machine executes monochrome toner coverage
control only.
