5. Troubleshooting
The goal of this procedure is to verify if the SC is caused by an incorrectly positioned feeler, which
may be caused by excess load put on the cam.
1. Open the upper guide plate [A] of the fusing unit and locate the belt smoothing roller contact/
separate feeler [B]. If the cut-out on the feeler is not visible, do Procedure 3.
* The top part of the fusing unit shown in this photo is gray because the unit is of the
prototype.
Cut-out [A] on the feeler is visible.
Continue with the next step.
2. Check if the brackets [A] and/or [B] are deformed.
If deformed, replace the fusing unit to complete the procedure.
If the brackets are not deformed, excess load on the cam may be the problem. Do the next
step.
3. Apply Fluotribo grease to the sliding surfaces [C] and [D] of the brackets [A] and [B]. Grease
amount: 5 ± 1 mm in diameter (0.1 to 0.4 gm)
