AR-C170M  SIMULATION  9 - 13

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 returns 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 (432 mm). If, 
however, the magnification ratio is set to a value greater than 
100% in procedure 1, the scanning length is changed accordingly.

The active sensors and detectors are highlighted.

• The light source unit is at the home position. a MHPS is 

highlighted.

• The light source unit is not at the home position. a MHPS is 

displayed normally.

Scanning is repeatedly performed until the [EXECUTE] key or the 
interruption key is pressed.

Operation test/check

Used to check the operations of the scanner unit and 
its control circuit.

Scanner (reading)

Operation

1. Select the copy (scanning) magnification ratio 

with 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.

Operation test/check

Used to check the scanner (scanning) unit and its 
control circuit.

Scanner (reading)

Operation

1. Select the copy (scanning) magnification ratio 

with the key (touch panel).  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. Select the scan mode (Color / B/W). 
3. Press the [EXECUTE] key.

Scanning is repeated under the conditions set in 
procedures 1 and 2.
During scanning, the [EXECUTE] key is 
highlighted.
