It is very important to apply grease properly when replacing fuser film sleeves. Improper installation will result in no-turning or damage of the film. Please follow the following instruction to replace fuser film sleeves:
- 1. Take off damaged/used fixing film from fixing film assembly or fuser.
- 2. Clean surface of heating element using Q-tip with alcohol.
- 3. Scoop up grease from the grease container with a spatula, a wooden spatula is preferred. Apply grease to about 15-20 places on the surface of the heater (heating element and fixture). Total amount of grease to apply is around 0.035oz or 1 gram.
Place the spatula at an angle on the surface of the heater and with one forward and backward movement spread the grease evenly over the surface. Make sure no grease is applied to the surface of the film sleeve.
Slide film onto heater so that the end with grounding ring positions to the same end where in the fuser the grounding conductor is located. And make sure they are in good contact. (There could be different kinds of grounding conductors in different models. Most common one is conductive rubber gear on pressure roller. In such case, the grounding ring should be in the same end and in good contact with the rubber gear.)
Turn the film many times by hands. When you feel film turning is free, you can assemble fixing film assembly with pressure roller.
