II. AUXILIARY PROCESS
A. Pre-Primary Charging
Figure 2-201
To prevent drum memory caused by the
positive charges of transfer, the CLC1000
executes pre-primary charging simultaneously
with pre-exposure.
Specifically, negative corona charges are
applied to the photosensitive drum before primary
charging to remove localized positive charges
remaining on the photosensitive drum.
B. Pre-Fixing Charging
Figure 2-202
The toner on the paper after separation is
more or less neutralized and yet is subject to
change while the paper is forwarded.
The CLC1000 causes its pre-fixing charging
assembly to apply a negative DC bias immediately
after separation of paper from the transfer belt to
retain the toner on the paper, thereby preventing
the toner from moving astray or causing offset
during fixing.
