Process Control Self Check - Gestetner B147 Service Manual

Process Control Self Check

This machine carries out potential control using a procedure called the process
control self check. There are seven types of process control self check, categorized
according to their execution timing.
1. Forced
This is done when SP3-126-1 is used.
2. Initial
This starts automatically when the power is turned on or when recovering from
energy saver mode, but only if the fusing unit pressure roller temperature is
60°C or less.
3. Interval: Job End
This starts automatically at the end of a print job when the total print counter for
this feature exceeds 200 (this can be changed with SP3-906-1). After any
process control is done (except for forced process control), the counters are
reset to "0."
4. Interval: Interrupt (default: not done)
This interrupts printing and then starts automatically when the machine makes
a certain number (A) of continuous color prints in the same job and the main
scan length detection is executed. After it is completed, the machine continues
to make prints.
The value A can be adjusted with SP3-906-2 (default: off).
At this time, only V
not done.
5. Non-use Time (default: not done)
This starts before the next print job if the machine has no job for a certain time
(M) after it makes more than a certain number (N) of prints.
M is adjusted with SP3-906-4 and N is adjusted with SP3-906-3.
6. After Toner End Recovery
This starts after recovery from a toner end condition.
7. After Developer Initialization
The machine executes the Auto Toner Density Adjustment (SP3-125-003). This
starts after a developer initialization is done. Developer initialization occurs
automatically after a new development unit has been installed.
