3. At Job End
There are separate counters for black-and-white and color pages. SP3551 sets the number
of pages that will trigger a process control self-check at the end of a job. SP3552 sets the
number of pages that will trigger a process control self-check during a job and not wait for
job end.
Black and White: If the current page count (SP3551-3) > SP3551-1, process control
will be done at the end of the job, if end-of-job process control has not been done for
250 pages
Color: If the current page count (SP3551-4) > SP3551-2, process control will be done
at the end of the job, if end-of-job process control has not been done for 250 pages
SP3551-3 or SP3551-4 can be set to "0" to disable this feature.
4. After a Specified Idle Time.
The machine will execute the process control self-check if the machine remains idle for the
length of time specified by SP3555. After the time set with SP3540-2 has elapsed, the
current temperature and humidity are compared with the temperature and humidity the last
time the drum stopped. If the difference is greater than the threshold values set with this
SP3555, initial process control executes. Specifically, this means this SP will trigger the
self-check under the following conditions:
The machine has not been used within a specified length of time since the last process
control self-check (SP3555-1).
Change in ambient temperature (SP3555-2).
Change in relative humidity (SP3555-3)
Change in absolute humidity (SP3555-4)
