6. Troubleshooting
1. Print out the Trimming Pattern (SP2-109 No.14).
2. If the image is a pattern A trapezoid:
a) Remove and reinstall the Fusing Unit.
b) Tighten the left fixing screw while you push up the unit's left side (until it stops).
3. If the image is a pattern B trapezoid, do the same for the unit's right side.
4. If the image is still printed out as a trapezoid, do Procedure 2 below.
Procedure 2: Minor Adjustment of the Fusing Unit Position (front-to-rear)
1. Remove and reinstall the fusing unit, then add a washer (t = 0.5 to 1.6) to the front fixing screw.
• This will increase the distance from the mainframe stay.
2. Check the image.
• Still NG: Go to the next step.
• OK: Adjustment Complete.
3. Add more washers (t = 0.5 to 1.6, as above).
6
• Too many washers can cause wrinkling in the paper.
• Still NG: Go to the next step.
• OK: Adjustment Complete.
4. Remove the fusing unit and all the washers added in steps 1 and 2 above.
5. Then, add washer(s) in the same way for the rear side.
Recommended Washers:
t = 0.5, 07080040Z or 07080040G
t = 0.8, 07080050Z or 07080050G
