1 - 1 Purpose Operation test/check
Function Used to check the operation of the scanner unit and its control circuit.
(Purpose)
Section Optical (Image scanning)
Item Operation
Operation/ 1. Select the copy (scanning) magnification ratio with the zoom key.
Procedure
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 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 (432mm). If, however, the magnification ratio is set to greater than
100%, the scanning length is changed accordingly.
Note
