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
machine is not recognized by your
computer.
1. Make sure your machine 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 installation DVD.
I cannot install the
scanner drivers.
(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 lists the current
accounts, one of which should be your name with
the word “Admin” below. If this is not the case,
contact your system administrator.
The file size is too
large.
The physical size of the document and
the amount of text / graphics on each
page affect the resulting file size and
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) produces
the largest-sized file.
For Windows
®
: see Change scan settings using the
TWAIN driver on page 27.
For Macintosh: see Change scan settings using the
TWAIN driver on page 65.

The rollers are worn. Paper dust has accumulated on the
