Monochrome printing and color printing
NOTE: Monochrome and full color printing can be switched between pages.
Monochrome printing
Waste toner bottle “1 cycle”: When the shaft rotates 90 degrees to change the
operation phase, the interface roller mechanism shakes the waste toner bottle in
order to make the waste toner level.
During monochrome printing, the
changer solenoid [“J” on page 6-19]
stays off, so the belt-transfer-roller
changer [“K” on page 6-19] does not
slide forward. Only the belt transfer
roller below the black OPC belt is
lifted, and the transfer belt contacts
the black OPC drum [N] only.
