Condition Suggested solutions The machine does not appear on the scanners list (continued). • Check if the MFP port is not busy. Since functional components of MFP (printer and scanner) share the same I/O interface (MFP port), the situation of simultaneous access of different "consumer" application to the same MFP 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 MFP ports configuration and select the port assigned to your scanner. MFP 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. The machine doesn't scan. • Check if a document is loaded into the machine. • Check if your machine is connected to the computer. Make sure if it is connected properly if I/ O error is reported while scanning. • Check if MFP port is not busy.

Condition Suggested solutions I can't print when I installed both Linux Print Package (LPP) and MFP driver on the same machine simultaneously. • Since both Linux Printer Package and MFP driver make a symbolic link to "lpr" printing command, which is commonly used on Unix clones, it is not recommended to use both package on the same machine. • If you still want to use both packages simultaneously, please install the LPP first. • If you want to uninstall only one of them, please uninstall both packages and install that one you want to use again. • If you don't want to uninstall MFP driver and install it again, you may make the necessary symbolic link yourself. Please, log in as root user and invoke the following command: ln -sf /usr/local/bin/samsung/slpr /usr/bin/lpr Can't scan via Gimp Front-end. • Check if Gimp Front-end has "Xsane:Device dialog." on the "Acquire" menu. If not, you should install Xsane plug-in for Gimp on the your computer. You can find Xsane plug-in package for Gimp on Linux distribution CD or Gimp home page. For the detail information, refer to the Help for Linux distribution CD or Gimp Front-end application. If you wish to use other kind of scan application, refer to the Help for application. I encounter error "Unable to open MFP port device file!" when printing a document. Please avoid changing print job parameters (via SLPR utility, for example) while a print job is in progress. Known versions of CUPS server break the print job whenever print options are changed and then try to restart the job from the beginning. Since Linux MFP driver locks MFP port while printing, the abrupt termination of the driver keeps the port locked and therefore unavailable for subsequent print jobs. If this situation occurred, please, try to release the MFP port. 9.11 Troubleshooting

To identify the source of the problem, you should
open MFP ports configuration and select the port

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

Condition
Suggested solutions
I can’t print when I
installed both Linux
Print Package (LPP)
and MFP driver on
the same machine
simultaneously.
•
Since both Linux Printer Package and MFP driver
make a symbolic link to “lpr” printing command,
which is commonly used on Unix clones, it is not
recommended to use both package on the same
machine.
•
If you still want to use both packages
simultaneously, please install the LPP first.
•
If you want to uninstall only one of them, please
uninstall both packages and install that one you
want to use again.
•
If you don’t want to uninstall MFP driver and install
it again, you may make the necessary symbolic link
yourself. Please, log in as root user and invoke the
following command:
ln -sf /usr/local/bin/samsung/slpr /usr/bin/lpr
Can’t scan via Gimp
Front-end.
•
Check if Gimp Front-end has “Xsane:Device
dialog.” on the “Acquire” menu. If not, you should
install Xsane plug-in for Gimp on the your
computer. You can find Xsane plug-in package for
Gimp on Linux distribution CD or Gimp home page.
For the detail information, refer to the Help for
Linux distribution CD or Gimp Front-end
application.
If you wish to use other kind of scan application,
refer to the Help for application.
I encounter error
“Unable to open MFP
port device file!”
when printing a
document.
Please avoid changing print job parameters (via SLPR
utility, for example) while a print job is in progress.
Known versions of CUPS server break the print job
whenever print options are changed and then try to
restart the job from the beginning. Since Linux MFP
driver locks MFP port while printing, the abrupt
termination of the driver keeps the port locked and
therefore unavailable for subsequent print jobs. If
this situation occurred, please, try to release the MFP
port.
