Fixing Assembly

The Fixing Assembly heats the dry, dusty toner particles to the melting point and presses them onto the paper. Because of high heat and the continual motion of the printing process, the Fixing Assembly is the most likely part of the printer to require service. Dust and dirt tend to collect in the Fixing Assembly, wearing grooves into the upper teflon roller and wearing out other small parts, such as the 14-tooth gear.

The Printer Works offers both new and rebuilt fixing assemblies, as well as parts. All SX, RX and TX printers use the same Fixing Assembly. Various parts have been revised, but all versions are interchangeable as long as they are the correct voltage.

Special Notes

Fixing assemblies sold as new or rebuilt include the Fixing Delivery Assembly (Diagram 370).

The only major difference between the 110/115V and 200/240V versions is the heater lamp. For 110/115V, use lamp Part No. RH7-4024-000. For 200/240V, use RH7-4025-000.

The 20-tooth gear (Item 18 in the Diagram) was changed in such a way that the new part does not exactly replace the old part, very unusual for Canon. The original part number, RS1-0116-000, was changed to RS1-0116-020. The -020 part is molded with small hubs that must be cut off with a sharp blade (an X-ACTO knife works well) so it will fit onto the original shaft. This could be avoided if the shaft were also replaced with a new version, but this shaft and plate assembly is one of the few parts Canon does not sell separately. A new plate and shaft assembly can be purchased only as part of an entire Fixing Assembly. This Canon policy makes it impossible to build an entire Fixing Assembly out of individually purchased parts.
