3-3. Adjustment / Settings

(1) Paper feed motor adjustment
1) When attaching the motor, fasten the screws so that the belt is properly stretched (in the direction indicated by the blue arrow in the
photo below).
2) After replacement, be sure to perform the service test print, and confirm that no strange noise or faulty print operation (due to
dislocation of the belt or gear, or out-of-phase motor, etc.) occurs.
- The screws securing the paper feed motor may be loosened only at replacement of the paper feed motor unit.
DO NOT loosen them in other cases.
(2) Document pressure plate sheet (sponge sheet) replacement
1) Peel off the cover sheet from the double-sided adhesive tape on the back of the document pressure plate sheet.
With the long-side down, position the upper-left corner of the document pressure plate sheet at the scanning reference point on the
platen glass (back left where the red lines cross in the photo above).
2) Attach the document pressure plate frame to the FAU, then slowly close the FAU while maintaining the hinge position. The
document pressure plate sheet will attach to the plate frame.
3) Open the FAU to confirm the following:
- No extension of the sponge edges over the mold part of the upper scanner cover.
- No gap between the platen glass reference edges and the corresponding sponge edges.
