Problem Possible cause and solutions The machine does not 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 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. I cannot scan via Gimp Front-end. • Check if Gimp Front-end has "Xsane: Device dialog." on the "Acquire" menu. If not, you should install Xsane plugin 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. Problem I encounter error "Cannot open port device file" when printing a document. Possible cause and solutions Please avoid changing the print job parameters (via LPR GUI, 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 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, please, try to release the port. Common Macintosh problems (SCX-4725FN only) Problem Suggested solutions The printer does not print PDF file correctly. Some parts of graphics, text or illustrations are missing. Incompatibility between the PDF file and the Acrobat products: Printing the PDF file as an image may solve this problem. Turn on Print as Image from the Acrobat printing options. Note: It will take longer to print when you print a PDF file as an image. The document has printed, but the print job has not disappeared from the spooler in Mac OS 10.3.2. Update your Mac OS to OS 10.3.3. or higher. Some letters are not displayed normally during the Cover page printing. This problem is caused because Mac OS can not create the font during the Cover page printing. English alphabet and numbers are displayed normally at the Cover page. 13.14

Troubleshooting>
The machine does not
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 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.
I cannot 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.

Common Macintosh problems
(

I encounter error
“Cannot open port
device file” when
printing a document.
Please avoid changing the print job
parameters (via LPR GUI, 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
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

Problem
Suggested solutions
The printer does not print
PDF file correctly. Some
parts of graphics, text or
illustrations are missing.
Incompatibility between the PDF file and
the Acrobat products:
Printing the PDF file as an image may
solve this problem. Turn on
Print as
Image
from the Acrobat printing options.
Note:
It will take longer to print when
you print a PDF file as an image.
The document has
printed, but the print job
has not disappeared from
the spooler in
Mac OS 10.3.2.
Update your Mac OS to OS 10.3.3. or
higher.
Some letters are not
displayed normally
during the Cover page
printing.
This problem is caused because Mac
OS can not create the font during the
Cover page printing. English alphabet
and numbers are displayed normally at
the Cover page.
