Samsung CLX-8540ND manual Problem, Possible Cause and Solution, Troubleshooting

Problem	Possible Cause and Solution
The machine does	• Check if a document is loaded into the
not scan.	machine.
	• Check if your machine is connected to the
	computer. Make sure 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 for different
	“consumer” applications to the same port is
	possible. To avoid possible conflicts, only one
	of them is allowed to gain control over the
	device at a time. The other “consumer” will
	encounter “device busy” response. This
	usually happens while starting the scan
	procedure, and an 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 you should
	press the Release port button, if you are sure
	that the port owner is not functioning properly.
I cannot scan via	• Check if Gimp Front-end has “Xsane: Device

	should install the Xsane plug-in for Gimp on
	your computer. You can find Xsane plug-in
	package for Gimp on downloaded Linux
	package (from Samsung website) or on the
	Gimp home page. For detailed information,
	refer to Help for Linux or Gimp Front-end
	application.
	If you wish to use an other kinds of scan
	applications, refer to the Help for application.

	and then try to restart the job from the beginning.
	Since Unified Linux Driver locks port while
	printing, the abrupt termination of the driver
	keeps the port locked and therefore unavailable
	for subsequent print jobs. If this situation
	occurred, try to release the port.

Problem	Possible Cause and Solution
Some color images	This is a known bug in Ghostscript (until GNU
come out all black.	Ghostscript version 7.05) when the base color
	space of the document is indexed color space
	and it is converted through CIE color space.
	Because Postscript uses CIE color space for
	Color Matching System, you should upgrade
	Ghostscript on your system to at least GNU
	Ghostscript version 7.06 or later. You can find
	recent Ghostscript versions at
