Common Linux problems
Problem Possible cause and 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 printers. Make sure that your
machine is displayed on the list. If not,
please, invoke Add new printer wizard to
set up your device.
• Check if the printer has 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,
please, press the Start button. After that
normal operation of the printer 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 a port is
claimed by a scanning application.
• Check if the port is not busy. Since
functional components of MFP (printer and
scanner) share the same I/O interface
(port), the situation of simultaneous access
of different “consumer” applications to the
same port are possible. To avoid possible
conflicts, only one of them at a time is
allowed to gain control over the device. The
other “consumer” will encounter “device
busy” response. You should open ports
configuration and select the port assigned
to your printer. In the Selected port pane
you can see if the port is occupied by some
other application. If this is the case, you
should wait for completion of the current job
or should press Release port button, if you
are sure that the present owner 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 later
version of CUPS (cups-1.1.22 or higher).
The machine does not
appear on the
scanners list.
• Check if your machine is attached to your
computer. Make sure that it is connected
properly via the USB port and is turned on.
• Check if the scanner driver for your
machine is installed in your system. Open
Unified 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. Check if the port is not
busy. Since functional components of MFP
(printer and scanner) share the same I/O
interface (port), the situation of
simultaneous access of different
“consumer” application 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
“consumer” will encounter “device busy”
response. This can usually happen while
starting scan procedure, and appropriate
message box appears.
• To identify the source of the problem, you
should open 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 some other application. If
this is the case, you should wait for
completion of the current job or you should
press Release port button, if you are sure
that the present port's owner is not
functioning properly.
The printer does not
print PDF file correctly.
Some parts of graphics,
text or illustrations are
missing.
Incompatibility between the PDF file and the
Acrobat products:
Printing the PDF file as an image may solve this
problem. Turn on
Print as Image
from the
Acrobat printing options.
Note:
It will take longer to print when you print a
PDF file as an image.
