	•	Check if your machine is connected to the
		computer. Make sure if it is connected
		properly if an I/O error is reported while
		scanning.
	•	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 will be displayed.
		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 the Release port button, if you are
		sure that the present port’s owner is not
		functioning properly.
