6.15.8 HOT ROLLER STRIPPER CLEANING
After a job of more than the specified number of pages ends, the fusing/exit motor
switches off and on to rotate the hot roller in order to dislodge toner clinging to the
hot roller strippers.
When printing ends, the fusing/exit motor switches off for 15 sec. then switches on
for 15 sec. This on/off cycle is repeated for the number of times specified with
SP3905 1 (Default: 1 off/on cycle). While the fusing/exit motor is switched off/on
during the cleaning cycle, all fans remain on.
NOTE: The hot roller strippers can also be force cleaned by adjusting and raising
the setting of SP5959 (Image Timing Adjustment) which allows the drum
and hot roller to turn freely to allow more time for cleaning before printing.
However, make sure that the customer understands that increasing this SP
setting slows down the first print time.
These are the SP codes that control hot roller stripper cleaning. (For details, refer
to Section “5. Service Tables”.

SP3905 1 Number of Rotations
