MX-M1204  ADJUSTMENTS  5 – 86

 

This adjustment is required in the following cases:
* When a paper jam occurs in the fusing section.
* When the lead edge of paper is folded in the fusing section.
* When skew is generated in the fusing section.
* When blur or improper focusing is generated on the lead edge

section or the rear edge section of an image on paper. 

* When wrinkle is generated on paper.
1) Remove the fusing unit.
2) Loosen the screw.

3) Slide the fusing paper guide up or down to adjust the position.

* Check and mark the scale position before the adjustment

(with a pencil, etc.), and slide to the left and the right evenly.

4)

Tighten the screw, and fix the fusing paper guide.

5)

Install the fusing unit to the main unit, and check the adjust-
ment result in the copy mode.
* There is no jam.
* The paper lead edge is not folded. 
* There is no skew.
* There is no blur of improper focusing on the lead edge and

the rear edge of an image on paper.

* There is no wrinkle on paper.

 

This adjustment must be performed in the following cases:
* If there occurred a paper jam (POIND_N) with winding around

the Drum when duplex copying.

The ADU section is provided with the decurler (curl correction)
function. The curl correction amount can be adjusted by rotating
the dial.
The adjustment can be made in 9 steps (Default value : 4). The
normally value is 4. The greater the value is from 4, the greater the
correction is.

NOTE: Perform a fine adjustment depending on the paper kind

and the use environment.

The direction of being pointed by the dial which is surrounded with
a  is the curl correction amount.
