• 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.
