Some color images
come out in
unexpected color.

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

The machine does
not print whole pages
and its output is half
page printed.

It is a known problem that occurs when a color

printer is used on version 8.51 or earlier of

Ghostscript, 64-bit Linux OS, and reported to as Ghostscript Bug


The problem is solved in AFPL Ghostscript v.

8.52 or above. Download the latest version of

AFPL Ghostscript from

projects/ghostscript/ and install it to solve this


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.

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, try to release the port.



The machine does
not appear on the
scanners list.

Check if your machine is attached to your

computer. Make sure that it is connected

properly via the USB port and is turned on.

Check if the scanner driver for your machine

is installed in your system. Open Unified

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.

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 appears.

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.
