When I press Scan in
my scanning software,
an error message
appears: Please
install scanner or
The scan was
aborted because the
scanner is not
powered on or not
connected properly.
This error message appears if your
scanner isn’t recognized by your
computer.
1. Make sure your scanner is connected properly.
2. Confirm that the Micro USB Cable is working and
that it is not frayed or damaged in any way.
If the error still appears after verifying that the Micro
USB Cable is connected properly, reinstall the
scanner driver from the DVD-ROM.

From Apple menu, select System Preferences >
System > Users & Groups. The left pane of the
window will list the current accounts, one of which
should be your name with the word “Admin”
underneath. If this is not
the case, contact your
system administrator.
The file size is too
large.
The size of the file will depend upon
many factors. The physical size of the
document and the amount of text /
graphics on each page are factors that
will affect the resulting file size. These
factors cannot be changed.
To produce the smallest scan file for a given
document, use the lowest resolution and Black and
White mode, and scan the smallest area possible.
Using the opposite settings (scanned in the highest
resolution, in the Colour mode, and scanning the
largest area possible) will produce the largest-sized
file.
