Taking Up The Fixing Cleaning Belt - Canon 1130 Service Manual

CHAPTER 8 FIXING SYSTEM
B. Taking Up the Fixing Cleaning Belt
The copier's fixing upper and lower rollers are each equipped with a cleaning mechanism
which uses a cleaning belt.
The cleaning belt is taken up about 0.4 mm each time the fixing cleaning belt solenoid (SL1 for
upper, SL2 for lower) turns on and off.
The number of times the fixing cleaning belt turns on and off depends on the length of paper
(feeding direction; both upper and lower solenoids).
Small size (182 to 216 mm)
Large size (217 to 432 mm)
Note 1: In the case of a transparency, once per sheet.
Note 2: The number of times the fixing cleaning belt turns on and off is the same for
both upper and lower solenoids.
A cut is made near the end of the cleaning belt. When the cleaning belt is taken up as far as the
cut, the arm so far supported by the belt drops through the cut, causing the fixing cleaning belt
sensor (PS11 for upper, PS67 for lower) to detect the end portion of the cleaning belt. The copier
will indicate a warning to communicate that the cleaning belt is running out when the sensor detects
the arm.

If the fixing cleaning belt solenoid has turned on/off about 2,000 times after
the warning has been issued for the belt, the cleaning belt counter will auto-
matically be cleared upon replacement of the belt (COUNTER>MISC>FIX-
