Auto Process Control Timing
„
Immediately after the main switch is turned on (and when it
comes back from auto off mode)
z
Process control is done if these conditions occur:
•
If fusing temperature is less than 100
°
C
•
If SP 3901 (auto process control enable/disable) is on
z
If SP 3904 is at 2, the full process control will be done. The
default is 0 (short process control, the wire is not cleaned).
„
At the end of a job, if process control was not done for more
than 24 hours (the charge corona wire is also cleaned)
z
This interval is set with SP 2966. At this time, a full process
control is done, and not a short process control.
„
Forced process control
z
When SP 2962 is done
•
This is a forced process control; use this SP to do the process
control procedure when it is necessary
Service manual, section 6.8.11, What Happens at Power On
ˆ
Auto Process Control is done at the times listed on this slide.
ˆ
SP2966: Adjust it if process control needs to be done more often, especially if the
wire keeps getting dirty.
¾
Normally, process control is done only at power-on, and this may only be a
short process control, so if the machine is always kept on, this SP may be
useful.
ˆ
If SP3901 is disabled, auto process control is not done. Then, development bias,
grid voltage, and laser power are set to the values in the SP modes listed in the
manual.

In addition, if process control is disabled, the ID sensor pattern is calibrated
differently.
