The machine does not
appear on the scanners
list (continued)
• 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.

• 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.
