3903 Drum Rotation Time Extension Mode
1 (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 to 1/0/1]
0: Extra drum rotation mode is off (default)
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.
2 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.
