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 the 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 from the printers list.
Look at the description in the Selected printer pane. If its status contains Stopped, press the Start button.
Normal operation of the machine should be restored. The “stopped” status might be activated when some
problems in printing occur.
• Check if your application has special print options 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 the
command line parameter in the command item.
The machine does not
print whole pages, and
output is printed on half
the page. 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.
“Cannot open port device
file” error message
appears when printing a
document. Avoid changing print job parameters (e.q., via LPR GUI) 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 the Port configuration window.
