7) After about 2 min, the adjustment value is stored in the

machine. Check that the mode was normally completed.

In case of an error end, remove the cause of the error, and
execute the automatic developer adjustment again.

8) Turn off/on the power, and the machine returns to the normal

mode and enters the warm-up mode.

Note: This adjustment must be performed after installing the

machine and its peripheral devices.

It is basically no need to perform the adjustment because it has
been made when shipping. If there should be a distortion as
shown in the figure below, perform the adjustment according to
the following procedures.

1) Use a level gauge to check to confirm that the scanner unit is

installed horizontally.

Make a copy, and if any distortion is found as shown in Fig 1
or Fig. 2, loosen the scanner fixing screw (M4 x 8) and the
cam A fixing screw (M3 x 12) to make an adjustment.

Shift the cam A in the direction of A by the difference of the image.

For one scale (one groove), shift by 0.5mm.

After shifting the cam, tighten the cam A fixing screw (M3 x 12).
Make a copy again and check to confirm that there is no distortion
on the image.

• Case of Fig. 2

Shift the cam A in the direction of B by the difference of the image.

For one scale (one groove), shift by 0.5mm.

After shifting the cam, tighten the cam A fixing screw (M3 x 12).
Make a copy again and check to confirm that there is no distortion
on the image.

After adjustment, tighten the fixing screw (M3 x 12) and the scan-
ner fixing screw (M4 x 8).

Attach the decoration seal to the screw hole.

1) Execute SIM 53-8 after completion of the distortion adjust-

ment.

2) If any distortion is made after execution of the simulation, exe-

cute the MB rail position adjustment. (Refer to "3-A OC scan
distortion adjustment (MB-B rail height adjustment)" in [8]
ADJUSTMENTS.)
