MX-M1100  ADJUSTMENTS  6 – 78
 
ADJ 19
Waste toner detection level 
adjustment
This adjustment is required in the following cases:
* The waste toner detection section has been disassembled.
* One or more parts of the waste toner detection section have
been replaced.
Turn the waste toner detection adjustment knob so that height from
upper surface of the adjustment knob to head edge of the tension
bar is 2.0 mm.
 
ADJ 20
Fusing paper guide position 
adjustment
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)
Enter the Sim. 43-33 mode.
2)
Enter the adjustment value with 10-key, and press [OK] button.
When the adjustment value is increased, the fusing paper
guide is shifted upward. When the value is decreased, it is
shifted downward.
A change in the adjustment value by 1 corresponds to a shift
by about 0.1mm.
3)
Check the adjustment 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.
Note: 
The fusing paper guide fixing position is adjusted by a jig in the fac-
tory.
In the field, never move the fixing plate of the fusing paper guide. 
In the market, the mechanical adjustment must not be performed
but the position adjustment may be performed with the simulation.
