3. 3. Dimensional Adjustment of Copied Image
3. 3. 1. Overview
The followings are the items in the copy image dimensional adjustment mode.
The adjustment must be performed in the following order.
Note: By carrying out the scanner related image position adjustment ((3)-b)~e)), an image position at reversing
is adjusted and that at the “Manually-placed original/Non-sort mode” (at which reversing is not performed)
does not come to the same position as adjusted above.
When the image position has to be matched at all modes, carry out a setting so that reversing can be
performed also at the “Manually-placed original/Non-sort mode” (setting mode: 08-627).
However, 0.7sec. of delay at first copy occurs when this setting is carried out.
