Question:

Sometimes it seems the scanner does not detect
paper.

Answer:

The AV25 scanner’s paper sensor is located at
the center of the paper guide.  Please place
whatever you want to scan somewhere
thereabout and use the slide guide to keep the
paper path straight.

Question:

Why some parallel port devices and software’s
keypro do not work with the AV25 scanner?

Answer:

If you would like to connect some parallel port
devices other than printer, please do not connect
them to the same parallel port that AV25
currently uses.  It is advisable that you use other
parallel ports to connect these devices or
keypro.  For instance, you can connect the
AV25 scanner to LPT1, and connect other
parallel port devices to LPT2.  Or you can add a
data switch to avoid the problem.
