	Add new printer wizard to set up your

	• Check if the machine is started. Open
	Printers configuration and select your
	machine on the printers list. Look at the
	description in the Selected printer pane. If its
	status contains Stopped string, press the
	Start button. After that normal operation of
	the machine should be restored. The
	“stopped” status might be activated when
	some problems in printing occurred. For
	instance, this could be an attempt to print a
	document when the port is claimed by a
	scanning application.
	• Ensure the port is not busy. Since functional
	components of machine (printer and scanner)
	share the same I/O interface (port), the
	situation of simultaneous access of different
	user applications 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 user will encounter “device

	configuration and select the port assigned to
	your machine. In the Selected port pane you
	can see if the port is occupied by some other
	application. If this is the case, you should
	either wait for completion of the current job or
	press the Release port button, if you are sure
	that the present application is not functioning
	properly.
	• Check if your application has special print
	option such as “-oraw”. If “-oraw” is specified
	in the command line parameter, then remove
	it to print properly. For Gimp front-end, select
	“print” -> “Setup printer” and edit command
	line parameter in the command item.

	Since Unified Linux Driver locks the port while

	To avoid possible conflicts, only one of them
	at a time is allowed to gain control over the
	device. The other user will encounter “device

	starting a scan procedure. An appropriate
	message box appears.
	To identify the source of the problem, open
	the 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 another
	application. If this is the case, you should
	either wait for completion of the current job or
	press the Release port button, if you are sure
	that the present port application is not
	functioning properly.
