MX-M1100  PHOTOCONDUCTOR SECTION  i – 5

Residual toner on the OPC drum is removed by the cleaning roller
and cleaning blade. 
The residual toner removed from the OPC drum surface is trans-
ported to the waste toner collection section by the waste toner
transport screw. 
The cleaning blade oscillates back and forward in synchronization
with the drum drive motor. By this movement, the cleaning perfor-
mance is improved.
