2)Select the paper feed tray with A3 (11" x 17") paper in it by changing the value of set item B.
3)Press [EXECUTE] key.
The check pattern is printed out.
4)Check the printed black image for any skew.
Measure the right angle level by using the six cross patterns printed in black.
There are following two methods of checking the black image for any skew (right angle).
Method 1:
Measure the length of the diagonal lines of the rectangle print pattern. Check the difference in the length of the diagonal lines for judgment of good or no good
Method 2:
Compare the right angle of vertical side/horizontal side of the rectangle print pattern and the right angle sides of A3 or 11 x 8.5 paper for judgment of good or no good.
(NOTE) In the case of Method 2, the right angle of paper to be used may not be exact. Be sure to check the right angle of paper to be used in advance.

If not, execute the following procedures.
5)Open the front cabinet, and remove the waste toner box.
6)Loosen the LSU unit fixing screws (2 pcs.) and shift the skew adjustment screw in the arrow direction to adjust the LSU (writing) unit skew.
(When Method 1 is used to check the black image for any skew (right angle) in procedure 4 in advance)
When the lengths of the diagonal line are C > D, shift the adjustment screw in the direction of Y.
When the lengths of the diagonal line are C < D, shift the adjustment screw in the direction of X.
(When Method 2 is used to check the black image for any skew (right angle) in procedure 4 in advance)
If the image is skewed in the arrow direction of A, shift the adjustment screw to X direction. If the image is skewed in the arrow direction of B, shift the adjustment screw to Y direction.

There are two kinds of the gamma target for the color balance automatic adjustment: the factory target and the service target.
FACTORY key and SERVICE key are used to select one of the above two.
Factory target color balance: Standard color balance
(The color balance can be selected from the three kinds of fixed ones with SIM63-11.)
Service target color balance: The color balance can be customized according to the user's request. (Variable)
When shipping from the factory, the service target gamma data and the factory target gamma data are the same.
Both are set to the standard color balance when shipping from the factory. For the service target, a customized color balance gamma can be registered with SIM63-7.

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 (automatic adjustment) is performed and the simulation is canceled, 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.)
(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.

2)Patch C or D of each of Y, C, M, and BK is very slightly copied.
Patch A of each of Y, M, C, and
BK are not copied.
1)The max. density section is not blurred.
3)Patch for each of C, M, Y, BK
The patch density is identical between patches or not reversed.
The patch density is changed gradually.
If the color balance of each patch of the process black (CMY mixed color) is slightly shifted to Magenta, it means that the adjustment is proper. If the color balance of the adjustment pattern printed in this mode is slightly shifted to Magenta, it is converted into the natural gray color balance by the color correction table in an actual copy mode. (When the color balance target is DEF 1.)
If the automatic adjustment cannot obtain satisfactory results of the copy color balance and density, use SIM 46-21 (ADJ 20C) (Manual adjustment).
11)Check the printer color balance and density.
There are two methods to check the color balance and density. (Method 1)
Use SIM 64-5 to print the print test pattern and check the print color balance and the density.
Set each setting value to the default and press [EXECUTE] key, and the print test pattern is printed.
(Refer to the item of the printer color balance and density check.)
(Method 2)
Use SIM67-25 to print the color balance adjustment sheet and compare the black patch color balance of each process (CMY) with the black patch. This procedure allows checking the color balance adjustment result correctly.

(When the color balance target is DEF 1.)
If a satisfactory result on the print color balance and the density is not obtained with the automatic adjustment, execute the manual adjustment (SIM 67-25) (ADJ 21B).
