Troubleshooting>
The machine does not
appear on the
scanners list
• Check if your machine is attached to
your computer. Make sure that it is
connected properly via the USB port and
is turned on.
• Check if the scanner driver for your
machine is installed in your system.
Open Unified Driver configurator, switch
to Scanners configuration, then press
Drivers. Make sure that driver with a
name corresponding to your machine's
name is listed in the window. Check if
the port is not busy. Since functional
components of MFP (printer and
scanner) share the same I/O interface
(port), the situation of simultaneous
access of different “consumer”
application to the same port is possible.
To avoid possible conflicts, only one of
them at a time is allowed to gain control
over the device. The other “consumer”
will encounter “device busy” response.
This can usually happen while starting
scan procedure, and appropriate
message box appears.
• To identify the source of the problem,
you should open ports configuration and
select the port assigned to your scanner.
port's symbol /dev/mfp0 corresponds to
LP:0 designation displayed in the
scanners’ options, /dev/mfp1 relates to
LP:1 and so on. USB ports start at /dev/
mfp4, so scanner on USB:0 relates to /
dev/mfp4 respectively and so forth
sequentially. In the Selected port pane
you can see if the port is occupied by
some other application. If this is the
case, you should wait for completion of
the current job or should press Release
port button, if you are sure that the
present port's owner is not functioning
properly.
Problem Possible Cause and Solution
The machine does not
scan
• Check if a document is loaded into the
machine.
• Check if your machine is connected to
the computer. Make sure if it is
connected properly if I/O error is
reported while scanning.
• Check if the port is not busy. Since
functional components of MFP (printer
and scanner) share the same I/O
interface (port), the situation of
simultaneous access of different
“consumer” application to the same port
is possible. To avoid possible conflicts,
only one of them at a time is allowed to
gain control over the device. The other
“consumer” will encounter “device busy”
response. This can usually happen while

I cannot scan via Gimp
Front-end.
• Check if Gimp Front-end has
“Xsane: Device dialog.” on the “Acquire”
menu. If not, you should install Xsane
plug-in for Gimp on the your computer.
You can find Xsane plug-in package for
Gimp on Linux distribution CD or Gimp
home page. For the detail information,
refer to the Help for Linux distribution CD
or Gimp Front-end application.
If you wish to use other kind of scan
application, refer to the Help for
application.
