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 times.
1. Forced
This is done when SP3-126-1 is used.
2. Initial
This starts automatically when the power is turned on, but only if the fusing unit
pressure roller temperature is less than 60
°
C.
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. 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
REF
is corrected. Potential control (V
D
, V
B
, V
L
correction) is
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
This starts after a developer initialization is done. Developer initialization occurs
automatically after a new development unit has been installed.
