Possible Cause and Solution
• 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 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, 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 document when 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" 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. 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.
• 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 pos-
sible. 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 should press Release port button,
if you are sure that the present port's owner is not functioning properly.
