MX-4101N  ADJUSTMENTS  5 – 95

6)

Set the color patch image (adjustment pattern) printed in the
procedure 5) on the document table.
Set the color patch image (adjustment pattern) printed in the
procedure 2) on the document table. Place the color patch
image so that the fine lines are on the left side. At that time,
place 5 sheets of white paper on the printed color patch image
(adjustment pattern).

7)

Press [FACTORY] key on the operation panel, and press
[EXECUTE] key.
When the color balance is customized with the manual color
balance adjustment (SIM 67-25) according to the user's
request and the color balance is registered as the service tar-
get with SIM 67-27, if the color balance is adjusted to that color
balance, select the service target.

The printer color balance adjustment (step 1) is automatically
performed and the color balance check patch image is printed
out.
If there is any streak or unclear print on the printed check pat-
tern, check the print engine for any problems.

8)

The initial setting menu of the half tone image correction is dis-
played. Press [OK] key.
The initial setting of the half tone image correction is per-
formed.

9)

When "COMPLETE THIS PROCEDURE" is displayed, the
adjustment operation is completed. Cancel SIM46-74.

NOTE: The adjustment result becomes valid only when the both

adjustments in the copy mode and in the printer mode are
completed.
For example, if the copy color balance adjustment (auto-
matic adjustment) is performed and the simulation is can-
celed, the adjustment result is invalid.

10) Check the copy color balance and density.

There are two methods to check the color balance and density.
(Method 1)
Use the servicing color test chart (UKOG-0317FCZZ/UKOG-
0317FC11) in the Text/Printed Photo mode (Manual) to check
the copy color balance and density. (Refer to the item of the
copy color balance and density check.)
When satisfactory color balance and density are not obtained
from the automatic adjustment by selecting the factory target in
procedure 4), change the factory color balance target with SIM
63-11 and repeat the procedures from 1).
If a satisfactory result is not obtained with the above proce-
dure, perform the manual color balance adjustment (ADJ
20C).
Also when the service target is selected in procedure 4) to exe-
cute the automatic adjustment and a satisfactory result is not
obtained, perform the manual color balance adjustment (ADJ
20C).
(Method 2)
By printing the color balance adjustment sheet with SIM 46-21
and comparing each process (CMY) black patch color balance
with the black patch, the color balance adjustment can be
checked more precisely.
