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.

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

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.
