[0 ~ 2000 / 1400 / 10 Volt/step]
Displays the status of fusing and discharge pin bias
control (on or off).
[0 ~ 1 / 1 / 1/step]
• 0: Control off
• 1: Control on
Adjusts the discharge plate voltage (paper separation
from transfer belt).
[–2500 ∼ 0 / –2000 / 100 Volt/step]
[–2500 ∼ 0 / –2000 / 100 Volt/step]
[–2500 ∼ 0 / –1500 / 100 Volt/step]
Controls the status of fusing bias control.
[0 ~ 2 / 2 / 1 /step]
If a current leak occurs because of a small hole in the
fusing belt surface, the machine automatically turns this
SP off. After this, the fusing bias is not applied until the
fusing counter is reset and the SP is set back to ON or
the PM counter is reset.
• 0: OFF fixed
The fusing and discharge pin bias are always off.
• 1: ON fixed
The fusing and discharge pin bias are always on. It
only turns off when SC 420 occurs.
• 2: Auto
The fusing and discharge pin bias turns off after 2K
prints.
It also turns off when SC 420 occurs, even if the
number of prints is less than 2K prints.
It turns on after you install a new fusing unit and
reset the PM counter with SP7-804-7.
Sets the charge corona unit cleaning interval.
[0 ~ 5000 / 600 / 100 counts/step]
See section 6 for details. SP7-925 displays the number
of counts since the last cleaning.
[100 ~ 5000 / 400 / 100 counts/step]
With this SP, you can adjust the interval for charge
corona cleaning in the middle of a job.
The charge corona cleaning is done after 600
development counts (SP2-801-1), at job end or after
1000 development counts (= the sum of the settings in
SP2-801-1 and -3) in the middle of the job.
Executes a forced charge corona unit cleaning.
Set to 1 to start cleaning.
