Separation (Step 6); Fixing (Step 7) - Canon 1000 Service Manual

H. Separation (step 6)
Figure 2-111
The CLC1000 separates paper from the
transfer belt using the rigidity of paper (curvature
separation). Since thin paper tends to have little
rigidity, it can wrap around the transfer belt, failing
to separate. To prevent such a problem, the
separation charging assembly applies AC corona
and DC bias, facilitating the separation of paper
from the transfer belt.

Fixing (step 7)

Figure 2-112
Depending on the selected color mode, a
maximum of four transfers takes place before the
paper is forwarded to the fixing assembly.
A pair of fixing rollers move the paper under
pressure and heat, thereby melting the toner
particles (of four colors) to produce as many colors
as needed, reproducing the original images and
fusing them into the fibers of the paper.
To prevent adhesion of toner from paper to the
surfaces of the fixing rollers (offset), the oil
applying roller constantly supplies silicone oil to the
rollers.
The upper fixing roller is cleaned by a cleaning
web, and the lower fixing roller is cleaned by a
cleaning web and a cleaning blade.
