PROCESS CONTROL
(2) Initial process control self check
The initial process control starts automatically when the power is turned on (or
when the machine returns to standby mode from sleep mode), but only if the hot
roller in the fusing unit is less than 100 degrees centigrade. This process control is
done only when SP3-125 (Set Potential Control Method) is set to "0 (Auto)."
(3) Interval process control self check
The interval process control starts automatically at the end of a copy job during
which the total number of copies exceeds a preset value.
The preset value can be defined using SP3-973 (Set Process Control Self Check
Interval). The factory setting is 150 sheets. The maximum possible interval is 500
sheets. Using a shorter interval reduces the machine's average copying speed.
Setting the process control interval to 0 disables the interval process control.
(4) Timed process control self check
The timer is reset to 6 hours after a process control self check, at the end of a copy
job, when the power is switched on, after toner end recovery, or if the front door is
opened and closed.
The 6-hour interval can be adjusted with SP 3-972.
(5) ACC-Run-Time Process Control Self Check
A process control self check that is active before the execution of ACC (auto color
calibration). The checks is identical to the interval process control self check.
