Common Linux problems

Refer to the Linux User’s Guide that came with your computer for further information on Linux error messages.
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.
