Copy density adjustment
(Outline)
Used to adjust the copy density in each copy mode.(The copy density can be set by changing the set value of
ASIC GAMMA ADJUST register.)
Setting in each copy mode is performed at exposure level 3. When the copy density (exposure) is adjusted
arbitrarily, the max, and min. exposure levels are automatically calculated and set. (The change amounts
(gradient, change amount) at level 1 – 5 are predetermined.)
(Operation/Procedure)
1. When this simulation is executed, warming up and shading are performed and the current set value is
     displayed in two digits.
2. Press the copy mode select key to select each setting mode and setting display.
 

∗ The copy mode setting is indicated with the following lamps as shown below.

3. Change the setting with the value up-down key and press the START key, and a copy will be made with the
     entered set value.
4. Press the clear key to store the set value and exit the simulation.

01

The value displayed after execution of this simulation can be set in the range of 0 – 99 with 50 as the center
value.
When the text mode set value is Gat3, for example, the GAMMA ADJUST register value set at Exp1 is:
Text Exp1 = Gat3 – 50 – 24
When 40 is set to Gat3, Text Exp1 = 40 – 50 – 24 = –34
Then set the GAMMA ADJUST register set value to –34.
Perform the same procedure for each mode and each Exp.
∗ The above table may subject to change.

∗ For the gradient, there is a similar table, though not specified here. The value set with SIM 46, however, is
  not reflected.
∗ The AE mode Exp selection is not specified, but corresponds to the grades for AE exposure selection in the
  former models.

FAX density overall adjustment
Used to set the normal mode density setup value added with each FAX resolution mode correction value to
each FAX resolution mode collectively.
(Operating procedure)
When this simulation is executed, warming up and shading are performed and the currently set value is
displayed in 2 digits. (Center value: 50)
Change the set value with the value up-down key and press the PRINT switch. The entered value is stored and
the simulation is terminated.
During this mode, the resolution mode cannot be selected.

The range of values dispalyed after execution of this simulation is 0 - 99 with 50 as the center.

∗ when reading FAX, the AE denisty can be selected in three levels (Dark, Normal, Light). However, in this

mode, copying is made in Normal. (There is no manual setup in reading FAX.)

13

FAX density adjustment (Normal mode)
Used to set the denisty set value in the normal mode individually.
(Operating procedure)
Same as the FAX density overall adjustment.

14

FAX denisty adjustment (Small character mode)
Used to set the denisty set value in the small character mode individually.
(Operating procedure)
Same as the FAX density overall adjustment.
Since, however, the small character mode has the Text document mode and the Photo document mode,
changeover can be made with the copy mode select key and the set value of the selected mode is displayed on
the copy quantity display. The copy mode setup is made as shown below.

15

FAX density adjustment (Fine mode)
Used to set the denisty set value in the fine mode individually.
(Operating procedure)
Same as the FAX density overall adjustment.

16

FAX density adjustment (Fine (300dpi) mode)
Used to set the denisty set value in the fine (300dpi) mode individually.
(Operating procedure)
Same as the FAX density overall adjustment.

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.

(Adjustment method)

1.

Set the print start position (A: AE ON), the lead edge void amount (B: TEXT ON), the scanning start position
(C: PHOTO ON) to zero and make a copy of a scale at 100%.

2.

Measure the image loss R (mm) of the scale.
Set as C = 10 

× R (mm). (Example: Set to 30.)

∗ When C is increased by 10, the image loss is decreased

by 1 mm. (Default: 5)

3.

Measure the distance H (mm) from the paper lead edge to
the image print start position.
Set as A = 10 

× R (mm). (Example: Set to 50.)

∗ When the value of A is increased by 10, the image lead

edge is shifted toward the paper lead edge by 1 mm.
(Default: 50)

4.

Set the lead edge void amount as B = 50 (2.5 mm).
(Default: 50)

∗ When the value of B is increased by 10, the void is

increased by about 1 mm.
(For 25 or less, however, the void amount becomes zero.)

✩ The SPF adjustment is made by adjusting the SPF image scan start position immediately after turning on the

power.

Paper center offset + OC/Document center offset + SPF document center offset
(Outline)
The center offset position of copy image on the copy paper and that of document scan are adjusted by
adjusting the scan left margin of ASIC and the print left margin register set value.
(Operation/Procedure)

1.

When this simulation is executed, the currently set value is displayed.

2.

For a machine with a multi manual paper feed unit installed, when the copy mode select key is pressed, each
set mode and display are changed.
For a machine with a single manual paper feed unit installed, when the copy mode select key is pressed,
each set mode and display are changed.
