Function

Determines how often the transfer
roller is cleaned.
0: The machine cleans the transfer
roller every 10 copies (it waits for
the job to finish).
1: The machine cleans the transfer
roller after every job.
Selects the polygon motor idling
time.
If the user sets original, touches a
key, or opens the platen cover/DF,
the polygon motor starts idling to
make a faster first copy. However,
with the default (25 s), the motor
stops if the user does nothing for 25
s, and stops 25 s after the end of a
job.
If set at "0", the polygon motor never
turns off during stand-by. However,
when the machine goes into energy
saver mode, the polygon motor turns
off regardless of this timer.
