<2> The gap between the belt drive roller and the bead should be checked on the F side. (Checking operations

will be facilitated if a pen-light is used.)
* If there is no gap (snaking in the R direction), conditions will be as shown in Fig. 1.

The rotation control plate F should be moved one (1) unit to the left. After the rotation control plate F has
been moved, the confirmation check described in 1. above should be carried out once again.

* If there is a gap of 0.5 mm to 1.5 mm present (neutral), it is not necessary to carry out adjustments to the

rotation control plate F.

* If there is a gap greater than 2 mm (snaking in the F direction) conditions will be as shown in Fig. 4. The

rotation control plate F should be moved one (1) unit to the right. After the rotation control plate F has
been moved, the confirmation check described in 1 above should be carried out once again.

<< Adjustment Point >>

<1> If the snaking direction does not reverse or become neutral by moving the rotation control plate F one (1)

unit, the rotation control plate F should be moved two (2) units from the centre position.

<2> If, after moving the rotation control plate two (2) units there is still not change in the snaking direction, is

should be assumed that there is a problem with the transfer UN or with the machine itself, and
confirmation checks should be carried out on both.

By moving the rotation control plate F to the left, the snaking direction will change from the conditions shown in
<Fig. 1> to the conditions shown in the figure below. Furthermore, if the rotation control plate F is moved to the
right, the snaking direction will be reversed.

(Points of caution to be observed during rotation control plate F adjustment operations.)

Caution:

After adjustments have been carried out, check to confirm that the transfer belt UN positioning section (metal

plate) is positioned during black-and-white mode and colour mode on the same step as the step-type hole of

the rotation control plate F.

In addition, when moving two (2) units to the left, caution should be exercised to make sure that movement to

the left does not occur more than two (2) units, as this will cause the rotation control plate F to come in contact

with the motor attachment plate.

After adjustments have been carried out, the image should be checked to confirm that there are no

abnormalities. When carrying out adjustments, particular attention should be given the edges of the Yellow

image area to make sure there are no abnormalities.

The image should be checked to confirm that the image darkness on the front edge and rear edge of the copy

paper is not exceptionally light.
