AR-C260/C260M  SETTING AND ADJUSTMENTS  8 - 7
1) Execute the process correction forcibly. (SIM44-6)
This simulation is used to correct the print density of the adjust-

3) Set the items A, B and C according to the table below.
4) Select the A4 (11 x 8 1/2) paper feed tray.
5) Press the [EXECUTE] key.
The focus adjustment pattern is printed.
6) Check the printed focus adjustment pattern for each color.
If focus is proper, the half-tone belts are printed properly. When
four or five half-tone belts of each color are printed and there is no
density difference in the main scanning direction (back and forth),
the focus is proper both on the front and the back sides.
7) If the above condition is not satisfied, turn the focus adjustment
screws on the front/rear frame sides to adjust focus.
Focus on the front side can be separately adjusted from focus on
the rear side.

• When the scanner (writing) unit is replaced.
• When the scanner (writing) unit is removed from the machine.
• When the print image includes skew.
(When the scanner (reading) unit is normal and the print image of
the print engine includes skew.)
• When a color image registration error occurs.
(There is an image registration difference in the main scanning direc-
tion.)
• When there is uneven density in the main scanning direction.
• When the color balance adjustment does not result in proper color
matching.

sary depending on the case)
