•
The Image Transfer/Paper Separator corona wires are automatically
cleaned under the following conditions. The cleaning function is, however,
disabled if the "Charge Wire Cleaning" function of "System Input" available
from the Tech. Rep. mode has been set to "Off".
(1) A period of 200 msec. has elapsed after Power Switch S1 has been
turned ON.
(2) The number of copies made exceeds 2,000 after S1 has been turned ON
and 10 minutes elapse after the last copy cycle has been completed (the
same timing as the auto clear when paper is empty).
(3) An Image Transfer/Paper Separator Coronas malfunction (C0210), which
has been detected, is reset.
(4) A misfeed/malfunction, which has been detected, is reset with a sheet of
paper remaining at the area near the Image Transfer/Paper Separator
Corona.
•
No control panel indication is given for the cleaning cycle and the copier
accepts the press of the Start Key, though it only feeds the paper up to the
Synchronizing Rollers and starts the scan after the cleaning cycle is
completed.
•
If the timing arrives for the timer power OFF function during a cleaning
cycle, the copier is turned OFF after the current cleaning cycle is
completed.
•
M22 is energized and deenergized by a signal output from pin 72 of IC4A
on PWB-A and fed via Image Transfer/Paper Separator Charge Wire
Cleaning Motor Drive Board PWB-P2.
