AR-203E/5420/M200/M201  ADJUSTMENTS  9 - 7

2) Print start position (Duplex back surface) (SPF/RSPF) 50-19

(PHOTO)

The size (length) of a document read from the SPF/RSPF is
detected, the image at the trailing edge of the first printing sur-
face is cut to make a void area. (The adjustment of void quantity
at the time when the cassette paper size is not recognized.)

The paper void quantity should be first adjusted before the image
cut trailing edge void quantity (SPF/RSPF) is adjusted.

1) Preparing test chart (Draw a scale at the rear end of one side

of a sheet of A/4 white paper or letter paper)

2) Set the test chart on the document glass as shown below.

3) Using the user simulation [18], set the paper size of the first

cassette.

• Letter paper: 4

• A4 paper: 3

4) Execute SIM 50-19 to turn on the PRINT mode lamp and make

the printing mode in OC-D mode.

Make a copy of the test chart to check the void area of the scale
on the image.

Adjust the setting so that the void area is 4 - 5 mm. An increase in
1 of setting represents 0.1 mm in void area.

1) Set the test chart so that the scale is positioned as shown

below.

2) Execute SIM 50-19 to turn on the SCAN mode lamp and make

the printing mode in the S-D mode.

3) Remove and reinsert the cassette.

Note: Make sure to carry out this step before making a copy during

this adjustment.

4) Make a copy and check the void area of the scale on the

image.
Adjust the setting so that the void area is 2 - 4 mm. An
increase of 1 in setting represents an increase of 0.1 mm in
void area.
Void position to be checked

1) When the main PWB is replaced.

2) When the EEPROM in the main PWB is replaced.

3) When "U2" trouble occurs.

4) When repairing or replacing the optical section.

Used to acquire the black level target value used for the black level
adjustment of white balance.

When SIM 63-02 is executed, the current correction value is dis-
played in 3 digits of 12bit hexadecimal number.

Place the gray gradation chart (UKOG-0162FCZZ) used as the
correction document so that the density 10 (black side) comes on
the left side and that the chart is upside down at the center of the
plate left center.

When [START] key is pressed, the mirror base unit scans the chart
and calculates the correction value.

After completion of correction, the corrected value is displayed on
the display section.

∗

Default: 0

∗

If the value is set to the default, operation is made with 0x60.

1) Initial display

2) [OK]/[ENTER]/[START] key: Correction start

<During canceling - When [Clear]/[Clear All] key is pressed->

After canceling, the machine goes into the sub code entry standby
mode. 

3) After execution

3) In case of an error

Details of function/operation

01

01

Mirror scan operation

[Function]
When [OK]/[ENTER]/[START] key is pressed, the home position is checked and the mirror base
performs full scan at the speed of the set magnification ratio.

During operation, the set magnification ratio is displayed.

The mirror home position sensor status is displayed with the "Drum replacement required lamp
(or the copy mode indicator for the AR-M200/M201)". (When the mirror is in the home position,
the lamp lights up.)

During operation, the copy lamp lights up.

When [Clear] key is pressed, if the operation is on the way, it is terminated and the machine
goes to the sub code entry standby mode.

02

Mirror home position sensor 
(MHPS) status display

[Function]
Monitors the mirror home position sensor, and makes the "Drum replacement required lamp (or
the copy mode indicator for the AR-M200/M201)" turn on during the sensor ON status.

06

Aging of mirror scanning

[Function]
When [OK]/[ENTER]/[START] key is pressed, the mirror base performs full scan at the speed of
the set magnification ratio.

During operation, the set magnification ratio is displayed.

After 3sec, the mirror base performs full scan again. 
∗ When [OK]/[ENTER]/[START] key is pressed once, the ready lamp remains OFF.
The mirror home position sensor status is displayed on the "Drum replacement required lamp
(or the copy mode indicator for the AR-M200/M201)." (The lamp is ON when the mirror is in the
home position.)

During aging, the copy lamp is ON.

[Operation] (AR-M200/M201)
The operation is similar to simulation 01-01.

02

01

SPF/RSPF aging operation 
(Only the AR-203E/M200/
M201 with the SPF/RSPF 
installed)

[Function]
When [OK]/[ENTER]/[START] key is pressed, the set magnification ratio is obtained. For the
SPF, the single-face document transport is performed. For the RSPF, the duplex document
transport is performed.

However, the operating conditions don't matter and the operation is not stopped even in case of
a jam. Also the magnification ratio is displayed on the LCD/display.

[Operation] (AR-M200/M201)
The operation is similar to simulation 01-01.
