Refer to Linux User’s Guide that came with your computer for further 

information on Linux error messages.

This is a known bug in Ghostscript (until GNU 

Ghostscript version 7.xx) when the base color 

space of the document is indexed RGB 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 8.xx or later. You can find 

recent Ghostscript versions at 

www.ghostscript.com.

It is a known problem that occurs when a color 

machine is used on version 8.51 or earlier of 

Ghostscript, 64-bit Linux OS, and has been 

reported to bugs.ghostscript.com as Ghostscript 

Bug 688252.The problem is solved in AFPL 

Ghostscript v. 8.52 or above. Download the 

latest version of AFPL Ghostscript from 

http://sourceforge.net/projects/ghostscript/ and 

install it to solve this problem.

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 detailed information, refer to the 

Help for Linux distribution CD or Gimp Front-end 

application. 

If you wish to use another kind of scan 

application, refer to application’s Help.

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 the port while 

printing, the abrupt termination of the driver 

keeps the port locked and unavailable for 

subsequent print jobs. If this situation occurs, try 

to release the port by selecting Release port in 

Port configuration window.

•

Ensure your machine is attached to your 

computer, connected properly via the USB 

port, and is turned on.

•

Ensure the scanner driver for your machine is 

installed in your system. Open Unified Linux 

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. 

•

Ensure the port is not busy. Since functional 

components of machine (printer and scanner) 

share the same I/O interface (port), the 

situation of simultaneous access of different 

“consumer” applications 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 

usually happens when starting a scan 

procedure. An appropriate message box 

appears.

To identify the source of the problem, open 

the 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 another 

application. If this is the case, you should 

either wait for completion of the current job or 

press the Release port button, if you are sure 

that the present port applicaton is not 

functioning properly.

•

Ensure a document is loaded into the 

machine, ensure your machine is connected 

to the computer.

•

If there is an I/O error while scanning.

Printing the PDF file as an image may enable 

the file to print. 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.

Update your MAC OS to OS MAC OS X 10.3.3. 

or higher.
