ROUBLESHOOTING
Possible Cause and Solution
• Check if your machine is attached to your computer.
Make sure that it is connected properly via the parallel
or USB port and is turned on.
• Check if the scanner driver for you machine is installed
in your system. Open MFP 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 MFP port is not busy. Since functional
components of MFP (printer and scanner) share the
same I/O interface (MFP port), the situation of
simultaneous access of different "consumer"
application to the same MFP 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 displays.
To identify the source of the problem, you should open
MFP ports configuration and select the port assigned
to your scanner. MFP 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.
