[1] PRODUCT OVERVIEW
The SF-A57/A18 is a reversing automatic document feeder (RADF)/
automatic document feeder (ADF) for the copier SF-2020/2120. The
SF-A57 is capable of automatically copying both sides of document
by inverting the document sheets up-side down, while feeding them.
Document sheets of different lengths and the same width may be set
in the document tray. An internal sensor in the ADF senses the
document size when the document is fed. The copier automatically
selects the proper copy paper corresponding to the document size
along with the appropriate magnification ratio.
If the appropriate copy paper, respective to the document size and
the magnification ratio, is not available, the copier stops copying and
indicates the required paper size on the display.
