Front/rear scan direction
(Outline)

(1) Front/rear scanning direction magnification ratio auto correction: (Performed by changing the set value of

ZOOM DATA register for asic.) The width of the reference line marked on the shading correction plate is
scanned to perform the front/rear direction magnification ratio adjustment automatically. (Performed by
changing the set value of ZOOM DATA register for ASIC.)

(2) Front/rear scanning direction magnification ratio manual correction: Used to set the front/rear (main scanning)

direction magnification ratio by key operations. (Performed by changing the set value of ZOOM DATA
register for ASIC.)

(3) Scanning direction magnification ratio correction: The scanning direction magnification ratio in the OC mode is

set by key operations. (Performed by changing the scanning speed.)

(4) SPF mode scanning direction magnification ratio correction: The scanning direction magnification ratio in the

OC mode is set by key operations. (Performed by changing the scanning speed.)

(Operation/Procedure)
1.  When this simulation is executed, the current set value is displayed in two digits. (Center value: 50)

2.  When the copy mode select key is pressed, the setting mode and the setting display are changed

sequentially.
∗ The selected adjustment mode is indicated by the lamps as follows:

3.  In the front/rear scanning direction adjustment, when the START key is pressed, the mirror base unit moves

to the white plate for shading and the width of the reference line is read and the correction value is
calculated and displayed and the value is stored.
In the case of the manual adjustment, enter the adjustment value with the 10-key and press the START key.
Then the entered value is stored and a copy is made. (An increase of 1 in the set value corresponds to an
increase of 1&.)

4.  Press the clear key to store the set value and exit the simulation.

In the front-rear direction magnification ratio correction:

(1)  The result of calculation of the scan correction value is 

±5% or less, “- -” is displayed.

(Cause) The white plate reference position error or the lens unit installing error

(2)  In case of a scanning error of the reference line, the JAM lamp is turned on.

(Cause) CCD error or no white plate
∗) If the automatic correction of magnification ratio does not work properly, adjust and correct manually.

Lead edge image position adjustment + Paper lead edge/rear edge void adjustment
(Outline)
This adjustment is used to adjust the copy image position and lead edge/rear edge void amount on the copy
paper by adjusting the image scan start position and the print start position (resist roller ON timing) at 100%.
(Operation/Procedure)

1.

When this simulation is executed, the currently set value is displayed in two digits. (Center value: 50)

2.

When the copy mode select key is pressed, each setting mode and the display are changed.

∗ The selected adjustment mode is indicated by the lamps as shown in the table below.

3.

Enter the adjustment value with the 10-key and press the start key. The set value is stored and a copy is
made. (When the set value is increased by 1, the void amount is shifted by 0.1 mm.)

4.

When the clear key is pressed, the set value is stored and the simulation mode is terminated.
