3903* Drum Rotation Time Extension Mode (B140/B246 Series)
001 (0:OFF/1:ON)
Turns on the drum rotation mode. This increases the time that the drum turns
freely after the machine is turned on. After this function is turned on with this SP,
it will be enabled only when SP3904 001 is set to “2”. If SP3904 001 is set to “0”
or “1”, the extra drum rotation mode will not be enabled.
[0~1/1]
0: Extra drum rotation mode is off.
1: After auto process control, the drum continues to turn until the fusing unit
gets to its operation temperature. Use this setting to decrease out-of-focus
copy images when the machine is used immediately after power-on.
002 Drum Rotation Time
Sets the amount of time the drum turns in the drum rotation mode before the first
copy after the machine is turned on. SP3903-001 must be on or this setting has
no effect.
[120~600/1]
3904 Warm Up Short Mode (B140/B246 Series)
Controls when corona wire cleaning is done to adjust the length of time that is
necessary for startup.
[0~2/1]
0: Charge corona wire not cleaned when the machine is turned on.
Warmup Time: 30 sec. (Short Process Control is done)
1: Charge corona wire cleaned only when the machine is turned on.
Warmup Time: 30 sec. + 40 sec. (for cleaning) = 70 sec. (Short Process Control
is done)
2: Normal startup procedure at power on:
Warmup Time: 240 sec. (Full Process Control is done; same as B064)
•
Potential sensor calibrated
• Drum starts to turn when fusing unit gets to the warmup temperature (not
done during Short Process Control)
• Potential sensor readings are used to adjust development bias, grid voltage,
laser diode.
• ID sensor calibrated (not done during Short Process Control)
• TD sensor calibrated (not done during Short Process Control)
