Common Linux problems

Problem		Possible Cause and Solution
The machine does not	•	Check if the printer driver is installed in
print		your system. Open Unified Driver
		configurator and switch to the Printers
		tab in Printers configuration window to
		look at the list of available printers. Make
		sure that your machine is displayed on
		the list. If not, please, invoke Add new
		printer wizard to set up your device.
	•	Check if the printer 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,
		please, press the Start button. After that
		normal operation of the printer should be
		restored. The “stopped” status might be
		activated when some problems in
		printing occurred. For instance, this
		could be an attempt to print document
		when port is claimed by a scanning
		application.
	•	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. You should open ports
		configuration and select the port
		assigned to your printer. 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 owner 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.

Problem		Possible Cause and Solution
The machine does not	•	Check if your machine is attached to

scanners list		connected properly via the USB port and
		is turned on.
	•	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.
