AR-C260/C260M  SETTING AND ADJUSTMENTS  8 - 8

1) Enter the SIM 64-1 mode.

SIM 64-1

2) Set the items A and B according to the table below.

3) Select the A3 (11 x 17) size paper feed tray.

4) Select Black (K) and press the [EXECUTE] key.

The grid patter (one page) is printed.

5) Check the printed grid pattern. (Check for image skew (distortion).)

If the right-angle level of the traverse print line is 0.5mm or less for
the longitudinal print line of paper, there is no need to adjust.

6) If the above conditions are not satisfied, remove the developing

unit and turn the print engine image skew adjustment screw to
adjust.

At that time, use SIM 7-1 to set DV CHECK DISABLE to Enable
and to disable the developing unit installation detection.

If skew is made in the arrow direction A, turn the adjustment screw
clockwise. If skew is made in the arrow direction B, turn the adjust-
ment screw counterclockwise.

7) Enter the SIM 61-4 mode.

SIM 61-4

8) Select the A4 (11 x 8.5) size paper feed tray. 

9) Press the [EXECUTE] key.

The print engine image skew adjustment pattern is printed. (One
page)

10) Check the printed image skew (distortion) pattern.

Compare the same color print pattern on the front frame side with
that on the rear frame side, and check that the difference between
the two highest-density areas is within 2 steps. (Compare the
same color print pattern on the front frame side with that on the
rear frame side. There is no need for the positions of the highest-
density areas of the print color patterns of all the colors to be
aligned on a line. Compare only the same color pattern positions.)

If the above conditions are not satisfied, remove the developing unit on
the left and turn the print engine image skew adjustment screw on the
front frame side.

To adjust the print engine image skew of Cyan, for example, remove
the Magenta developing unit. (To adjust the print engine image skew of
Yellow, however, this is not required.)

At that time, use SIM 7-1 to set DV CHECK DISABLE to Enable and to
disable the developing unit installation detection.
