MX-C300P  ADJUSTMENTS  5 – 19

 

1)

Enter the SIM 67-25 mode.

2)

Select the color and the adjustment point to be adjusted.

3)

Enter the adjustment value and press [OK] key.

The adjustment value is set in the range of 1 - 255.

To increase the density, increase the adjustment value. To
decrease the density, decrease the adjustment value.

4)

Press [STOP] key to cancel SIM67-25.

5)

Check the adjustment result by using either of the printer color
balance and density check method 1 or 2.

 

When SIM 67-22 is done, the adjustment result of SIM 67-21 is
cleared.                                                                                  
The adjustment results of SIM 67-21 are registered in SIM 67-33.
To clear the adjustment results of SIM 67-21, use SIM 67-52. 
The adjustment results values of [Easy Calibration] mode in the
system setting menu are registered in SIM 67-25 and are cleared
by SIM 67-21. 

1)

Enter the SIM 67-21 mode.

2)

Press [OK] key.

(A4 or 11" x 8.5" paper is automatically selected and the sim-
ple color balance adjustment pattern is printed.)

3)

Find out the patch which is closest to the neutral gray among
the patches of the printed simple color balance adjustment pat-
tern.

When the patch out of printed range needs to be selected,
select the highest or lowest patch once and perform the adjust-
ment.  By this way, the highest or lowest patch becomes the
center of the patch pattern (No.4) and the printing ranged is
expanded.  However, this adjustment should be finished in the
default printing range. Therefore, if the patch out of printed
range needs to be selected, check the printing engine part.  

4)

Enter the X and Y coordinate values of the simple color bal-
ance adjustment pattern patch which was found in procedure
3) as the adjustment values.

Enter the adjustment value, and press [OK] key.

5)

The test pattern is printed out again. When "COMPLETE" is
displayed, press [STOP] key to cancel SIM67-21.

6)

Check the adjustment result by using printed test pattern.

MX-C300P  ADJUSTMENTS  5 – 20

 

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.

* When there is request from the user.

1)

Enter the SIM 67-36 mode.

2)

Enter the adjustment value, and press [OK] key.

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.

 

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.

1)

Enter the SIM 67-34 mode.

2)

Enter the item 1 or 2 with the 10 keys.

3)

Press [OK] key.

* If a tone gap occurs on part of high density, set 0 to item 1

and 2

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 1 and 2.

The tone gap may occur in high density part.

 

This adjustment is to set printer calibration setting values (SIM 67-
21/67-22)to the default values. 
This adjustment is used when the color cannot be restored to the
correct color tone by the operation mistakes or other causes.  
Note that the color cannot be restored to the original condition at
the initial installation and perform the adjustments described in
[ADJ 6] section. After performing SIM 67-31, perform [ADJ 6] from
the beginning.                                                                                                
* This function is only for MX-C300P/C300PE/300E.  

1)

Enter the SIM 67-31 mode.

2)

Press [OK] key and printer calibration setting values are set to
the default values. 

 

1)

Enter the SIM 67-52 mode.

2)

Enter [1] to clear with 10 keys and press [OK] key.

MX-C300P  ADJUSTMENTS  5 – 21

 

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.

tion mode, a malfunction may result. In this case, turn
OFF/ON the main power source.

In the simulation mode, the keys are displayed by following the key
arrangement of the Neo MFP.  The key arrangement of the Neo
MFP and the Neo Printer are different.  
In the following list, the correlation diagram is described. 

The function of [ * ] (Neo MFP) is the same as the [LOGOUT] key
(Neo Printer).  

The function of [ # ] (Neo MFP) is the same as the [SYMBOL](@)
key (Neo Printer).  

The function of [ CA ] (Neo MFP) is the same as the [HOME] key
