26 Centering error, skew (how to set paper in PFU)
[Symptom]
Centering error or paper skew occurs when using PFU
[Probable causes and solution]
Side guide plate is set improperly.
1) Side guide plate is not set symmetric at the center. To correct it, check the scale on the
side guides front and rear.
2) The gap between paper edge and side guide is too wide (paper feeding is unstable)
To correct it, minimize the gap.
[How to adjust the gap between paper and side guides]
When the tray is pulled out, the bottom plate descends as shown in the following figure.
Adjust the side guides position with the paper feeding position. (Bottom plate ascend
position.)
When the tray is pulled
out, the bottom plate
descends
Bottom
plate
The paper is guided with the bottom
plate lift up status
Do not adjust here.
Turn the volume and move
to the rear side
Tray does not descend. Side guide
can be adjusted at the paper feeding
position.
Be sure to return the volume to the original position.
If too much paper is loaded for the adjustment, the bottom plate
descends with the weight of the paper. Therefore, load 5 to 10
sheets for the adjustment.
