Purpose Operation test/check
Function Used to check the operation of the scanner unit and its
(Purpose) control circuit.
Section Optical (Image scanning)
Item Operation
Operation/ 1. Select the copy (scanning) magnification ratio with
Procedure the zoom key.
The magnification ratio can be increased or
decreased with the [ZOOM] key by the increment of
1%.
The selected magnification ratio is displayed on the
magnification ratio display.
2. Press the [EXECUTE] key.
Scanning is performed at the magnification ratio set in procedure
1 is executed. During scanning, the [EXECUTE] key is highlighted.
If the [EXECUTE] key is pressed under this state, the operation is
interrupted. After completion of scanning, the [EXECUTE] key re-
turns to the normal display.
To resume scanning, start with procedure 2.
To change the magnification ratio, start with procedure 1.
Scanning is performed at the max. scanning length (432mm). If, how-
ever, the magnification ratio is set to greater than 100%, the scanning
length is changed accordingly.

Purpose Operation test/check
Function Used to check the operation of sensors and detectors
(Purpose) in the scanner section and the related circuit.
Section Optical (Image scanning)
Item Operation
Operation/ The operations of sensors and detectors in the scanner
Procedure section are displayed.
The active sensors and detectors are highlighted.

Purpose Operation test/check
Function Used to check the operation of the automatic document
(Purpose) feeder unit and its control circuit.
Section Automatic document feeder
Item Operation
Operation/ 1. Select the aging mode with the key.
Procedure
When selection is made, the selected item is
highlighted.
[1:SIDE]: Single copy aging mode
[2:SIDE]: Duplex copy aging mode
(Note) [2:SIDE] is displayed only when the unit
which allows duplex copy is installed.
2. Select the copy magnification ratio with the key.
(The magnification ratio can be increased or decreased in the in-
crement of 1% with the [ZOOM] key.)
The selected magnification ratio is displayed on the magnification
ratio display on the screen.
The magnification ratio can be set only when SPF/DF is installed.
3. Press the [EXECUTE] key.
Aging of the document feeder is executed under the conditions
specified with procedures 1 and 2.
During aging, the [EXECUTE] key is highlighted. If the [EXECUTE]
key is pressed while it is highlighted, the operation is interrupted.
When two or more operations are selected in procedure 1,
"1:SIDE" (single copy aging mode) is unconditionally performed
and the other highlighted displays return to the normal display.
(AR-250/280/281/285/286/335/336)
To resume aging, execute with procedure 3.
To change the conditions for aging, execute with procedure 1.
*
When the SPF/ADF is installed , the magnification ratio can be
adjusted in the range of 64% - 200%.
(AR-287/337)
To change the conditions for aging, execute with procedure 1.
