Fixing Block - Canon CP660 Service Manual

CHAPTER 1 GENERAL DESCRIPTION
G.

Fixing Block

The toner image transferred to paper in the transfer block merely "sits" on the paper
by the work of static electricity, and would collapse if subject to the slightest impact.
In this block, the four color toners are fused into the fibers of the paper so that they
will turn into a permanent image.
Step 12 (fixing)
The surface of the upper and lower rollers is coated with Teflon tubing material with
good separation characteristics.
A negative DC bias is applied to the upper fixing roller to prevent toner on the paper
from sticking to the rollers.
DC bias
