<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 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 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.

I encounter error 
“Cannot open port 
device file” when 
printing a document.

Please avoid changing 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. 

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.

: 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.
