MX-C250 ADJUSTMENTS 5 – 43
To increase the density, increase the adjustment value. To
decrease the density, decrease the adjustment value. Repeat
the procedure 2) to 3) until a satisfactory result is obtained.
10-B
Printer density adjustment (low density part
density adjustment) (Normally unnecessary
to adjust)
This procedure is to adjust image density of low density area in
printer mode.
Adjust to reproduction (not reproduction) setting of the low density
image.
This adjustment is required in the following cases.
* When reproduction of low density image is required. When repro-
duction of low density image is not required, conversely.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When there is request from the user.
1)
Enter the SIM 67-36 mode.
2)
Enter the adjustment value and press the [OK] key.
In case of increase of the image density on low density part,
increase the adjustment value. In case of increase of the
image density on low density part, increase the adjustment
value. For diluting the image density on low density part,
decrease the adjustment value.
10-C
Printer high density part density correction
setting (high density part tone gap
countermeasure) (Normally unnecessary to
the setting change)
This procedure is to adjust image density of low density area in
printer mode.
This setting normally not required. When, however, there are case
of following, change the setting.
* When a tone gap occurs on part of high density.
* When there is necessity to increase the density of the part of
high density.
* The CIS unit has been replaced.
* U2 trouble has occurred.
* When the MFPC PWB is replaced.
a. Adjustment procedure
1)
Enter the SIM 67-34 mode.
2)
Enter the adjustment value and press the [OK] key.
* If a tone gap occurs on part of high density, set 0 to item A and B
The density of high density part decreases. However, the tone
gap is better.
* In case of more increase of the density on high density part, set 1
to item A and B.
The tone gap may occur in high density part.
(NOTE) If the setting values of item 1 or 2 are changed, density of
the high density part is changed.
ADJ 11
Fusing paper guide position
adjustment
Normally there is no need to perform this adjustment. In the follow-
ing cases, perform this adjustment.
* When a paper jam occurs in the fusing section.
* When wrinkles are made on paper in the fusing section.
* When an image deflection or an image blur is generated in the
paper rear edge section.
1)
Change the screw position of the fusing paper guide by refer-
ring the figure.
2)
The standard fixing position is the center part of the screw
holes. Change the position according to the situation.
* When wrinkles are generated on paper, change the position
in the arrow direction B.
* When an image deflection or an image blur is generated in
the paper rear edge section, change the position in the
arrow direction A.
Normally, the hole on the fusing paper guide standard fixing
position is used to fix the fusing paper guide.
