- Use spreaders to disconnect the bearing from the front end of the pressure roller [A] (
x1).
- Pull the other bearing from the other end of the pressure roller (there is no fastener on the other bearing).
- Spin the races of the bearings and make sure that they rotate easily.
- If they do not turn easily, they must be replaced.
- At the bottom of the frame (near the front), inspect and clean the pressure roller thermistor [A] with a clean cloth.
Always inspect and clean the pressure roller for contamination by grease before re-installing it.
- Grease contamination can cause uneven heating on the surface of the roller and cause problems during fusing.
- Clean the entire surface of the roller with a dry cloth.
- Next, clean the entire surface with a cloth dampened with water (not alcohol).
- Finally, clean the entire surface again with a dry cloth.
- Use a small brush, or the tip of a small flat-tip screwdriver, etc. to apply Fluotribo MG grease to the inside surfaces of the pressure roller races.
