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
configuration window 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
Printers configuration and select your
machine on the printers list. Look at the
description in the Selected printer pane. If its
status contains Stopped 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.
•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
user 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 user will encounter “device
busy” response. You should open ports
configuration and select the port assigned to
your machine. 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 UNIXPrinting 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.ghostscript.com.
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
www.ghostscript.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://sourceforge.net/projects/gho
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 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.
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
Printing System) 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.
