When I click Scan in
my scanning software,
an error message
appears: Cannot find
the scanner or
Operation system
error.
This error message appears if your
scanner is not recognized by your
computer.
1. Make sure your scanner is connected correctly.
2. Confirm that the USB cable is working and that it
is not frayed or damaged in any way.
If the error still appears after verifying that the
USB cable is connected correctly, reinstall the
scanner driver from Brother’s installation DVD.
I cannot install the
scanner drivers.
(Windows

administrator privileges.
Log into Windows

with administrator rights.
I cannot install the
scanner drivers.
(Macintosh)
You may not have been given
administrator privileges.
From the 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 Color mode, and
scanning the largest area possible) will produce
the largest-sized file.
For Windows

: see Change scan settings using the
TWAIN driver on page 24.
For Macintosh: see Change scan settings using the
TWAIN driver on page 62.

I want to use a
USB hub.
- Use your scanner without connecting to a USB hub.
The rollers are worn. Paper dust has accumulated on the
surface of the rollers.
Clean the rollers every 5,000 scans.
