	• Check if the scanner driver for your machine
	is installed in your system. Open Unified
	Driver 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 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.
	• To identify the source of the problem, you
	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
	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.
