6. Troubleshooting
Refer to the Linux User’s Guide that came with your computer for further information on Linux error messages.
The machine does not
appear on the scanners
list.
• Ensure your machine is attached to your computer, connected properly via the USB port, and is turned on.
• Ensure the scanner driver for your machine is installed in your system. Open Unified Linux Driver configurator,
switch to Sca nners c onfig urati on, the n pres s Driv ers. Ma ke sur e that driver with a name c orres pondin g to yo ur
machine's name is listed in the window.
• Ensure the port is not busy. Since functional components of machin e (printer and scanner) share the same I/O
interface (port), the situation of simultaneous access of different user applications to the same port is possible.
To avoid possible conflicts, only one of them a t a ti me is allo wed t o gai n control over the device. The other user
will encounter “device busy” response. This usually happens when starting a scan procedure. An appropriate
message box appears.
To identify the source of the problem, open the 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 another
appli catio n. If this i s the case, you s hould eithe r wai t for completion of the current job or press the Release port
button, if you are sure that the present port applicaton is not functioning properly.
The machine does not
scan.
• Ensure a document is loaded into the machine, ensure your machine is connected to the computer.
• If there is an I/O error while scanning.
