G. Fixing/Delivery Assembly
1. Outline
The following loads are driven by the fixing motor (M9).
• Upper fixing roller
• Lower fixing roller
• Delivery roller
• Oil applying roller
• Upper fixing web (locking)
To ensure proper fixing when making two-sided copies or copying on transparencies or to suit various
copying modes, the CLC1000 controls the fixing speed over six settings.
The upper roller and the lower roller are each equipped with a fixing cleaning web. The upper fixing web
is driven by the upper fixing web take-up solenoid (SL3), and the lower web is driven by the lower fixing web
motor (M30).
In addition, the lower fixing roller is equipped with a spring locking type cleaning blade. The separation
claw used to prevent wrapping of paper round the lower fixing roller is operated to move away from the lower
fixing roller by the drive of the separation claw solenoid (SL15) to prevent damage to the lower fixing roller.
