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.
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

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.

[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 increment 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 is installed.
The magnification ratio can be set only when SPF 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.
To resume aging, execute with procedure 3.
To change the conditions for aging, execute with procedure 1.
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.
To resume aging, execute with procedure 3.
To change the conditions for aging, execute with procedure 1.
When the SPF is installed , the magnification ratio can be adjusted in the range of 64% - 200%.
