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
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 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).

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.

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 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.

The machine does
not appear on the

scanners list.

Ensure your machine is attached to your
computer, connected properly via the USB

port, and is turned on.

Ensure the scanner driver for your machine is

installed in your system. Open Unified Linux
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.

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. This usually happens when
starting a scan procedure. An appropriate

message box appears.
To identify the source of the problem, open

the 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 another

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 port application is not
functioning properly.
