CHAPTER 11 TROUBLESHOOTING

Adjusting the Mirror Position (optical length between No. 1 mirror and No. 2 mirror) If you have replaced the scanner drive cable, you must adjust the mirror position, by changing the position of the cable retainer of the No. 1 mirror mount. Reference: 1. As more and more copies are made, the cable tends to become slack, requiring adjustment. 2. If the optical length between the No. 1 mirror and the No. 2 mirror is not correct, the horizontal reproduction ratio will be wrong, causing poor sharpness or blurred images.

c.

1) Fit the mirror positioning tool (FY9-3009) as shown.

Figure 11-205 2) Remove the copyboard glass. (See Chapter 7.III.C.1. �Removing the Copyboard Glass�.) 3) Loosen the screws used to secure the cable retainer at the rear and the front of the No. 1 mirror mount [1].
