Used to set the specifications with SIM26 according to the cus-
tomer's request.

To customize the following items after completion of the destination
setup, change the set values.

Step 1: Image Skew Check

Perform Simulation 50-22 (select "ALL").

If Image Skew is "OK" for all Colors, proceed to Step 2.

If Image Skew is "NG" for any Colors, Proceed to Black Laser
Skew Adjustment Procedure.

When complete, go back to Simulation 50-22 (select "ALL"), and
make Color Laser Skew adjustments as shown on machine dis-
play. Repeat until proper specification is reached. When Color
Laser Skew Adjustment is complete, proceed to Step 2.

Step 2: Image Loss, Void Area, Image Off-center adjustment

Perform Simulation 50-28.

Complete all of the adjustments as listed in order. When Adjust-
ments are complete, proceed to Step 3.

Step 3: Copy/Printer Color Balance Adjustment

Perform Simulation 46-74.

Summary of adjustments, please perform in order to achieve the
best quality results.

1)

Press [REGIST] button in SIM50-22 mode to execute the auto-
matic image registration adjustment.

2)

The current skew level is displayed on the SKEW display
menu.

3)

Put down the displayed skew level value.

* When the machine is displays an "NG" condition for color laser

skew check/adjustment as well all colors laser skew adjustments
must to be checked or performed.

(Meaning of the skew level value)

* When "R" is displayed in front of the value, turn and click the

skew adjustment screw (LSU) clockwise by the number of the
value.

* When "L" is displayed in front of the value, turn and click the

skew adjustment screw (LSU) counterclockwise by the number
of the value.

At that time, the fractional part after the decimal point is rounded.

NOTE: The K (black) image skew level cannot be checked with

this adjustment.

To check and adjust the K (black) image skew, follow the
procedures below and execute the adjustment.

1)

Enter SIM61-4 mode.

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.

a) Measure the length of the diagonal lines of the rectangle
print pattern.
