Common Linux problems
CONDITION SUGGESTED SOLUTIONS
The machine does
not print.
• Check if the printer driver is installed in your
system. Open Unified Driver Configurator and
switch to the Printers tab in Printers config-
uration win
dow to look at the list of available
machines. Make sure that your machine is
displayed on the list. If not, open Add new
printer wizard to set up your device.
• Check if
the machine is started. Open Print-
ers configuration
and select your machine
on the printers list. Look at the description in
the Selected printer pane. If its status con-
tains S
topped string, press the Start button.
After that normal operation of the machine
should be restored. The “stopped” status
might be activated when some problems in
printing occurred. For instance, this could be
an attempt to print a document when the port
is claimed by a scanning application.
• En
sure the port is not busy. Since functional
components of machine (printer and scanner)
share the same I/O interface (port), the situa-
tion of simultaneous access of different user
appl
ications 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 user will encounter “device busy”
response. You should open ports configura-
tion and select the port assigned to your
m
achine. In the Selected port pane you can
see if the port is occupied by some other
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 application is not functioning
properly.
• Check if
your application has special print
option such as “-oraw”. If “-oraw” is specified
in the command line parameter, then remove
it to print properly. For Gimp front-end, select
“print” -> “Setup printer” and edit command
line parameter in the command item.
• The CUPS (Common UNIX Printing System)
version distributed with SuSE Linux 9.2
(cups-1.1.21) has a problem with ipp (Internet
Printing Protocol) printing.Use the socket
printing instead of ipp or install a later version
of CUPS (cups-1.1.22 or higher).
Some color images
come out all black.
This is a known bug in Ghostscript (until GNU
Ghostscript version 7.05) when the base color
space of the document is indexed 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 7.06 or later. You can find
recent Ghostscript versions at www.ghost-
script.com.
Some color images
com
e out in unex-
pected 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 versi
ons at www.ghost-
script.com.
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
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://source-
forge.net/projects/gho
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 (Common UNIX Print-
ing System) server break the print job whenever
p
rint 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 select-
ing Releas
e port in Port configuration window.
Refer to Linux User’s Guide that came with your computer for further
information on Linux error messages.
Common Macintosh problems

The machine does
not print PDF files
correctly. Some
parts of graphics,
text, or illustrations
are missing.
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.
