Troubleshooting

The machine does

not appear on the

scanners list

(continued).

• Check if the MFP port is not busy. Since functional

components of MFP (printer and scanner) share the

same I/O interface (MFP port), the situation of

simultaneous access of different “consumer”

application to the same MFP 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 MFP ports configuration and select the port

assigned to your scanner. MFP 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.

The machine doesn’t

scan.

• Check if a document is loaded into the machine.

• Check if your machine is connected to the

computer. Make sure if it is connected properly if I/

O error is reported while scanning.

• Check if MFP port is not busy. Since functional

components of MFP (printer and scanner) share the

same I/O interface (MFP port), the situation of

simultaneous access of different “consumer”

application to the same MFP port is possible. To

avoid possible conflicts, only one of them at a time

Condition Suggested solutions

I can’t print when I

installed both Linux

Print Package (LPP)

and MFP driver on

the same machine

simultaneously.

• Since both Linux Printer Package and MFP driver

make a symbolic link to “lpr” printing command,

which is commonly used on Unix clones, it is not

recommended to use both package on the same

machine.

• If you still want to use both packages

simultaneously, please install the LPP first.

• If you want to uninstall only one of them, please

uninstall both packages and install that one you

want to use again.

• If you don’t want to uninstall MFP driver and install

it again, you may make the necessary symbolic link

yourself. Please, log in as root user and invoke the

following command:

ln -sf /usr/local/bin/Xerox/slpr /usr/bin/lpr

Can’t 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 detail information, refer to the Help for

Linux distribution CD or Gimp Front-end

application.

If you wish to use other kind of scan application,

refer to the Help for application.

I encounter error

“Unable to open MFP

port device file!”

when printing a

document.

Please avoid changing print job parameters (via SLPR

utility, 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 Linux MFP

driver locks MFP port while printing, the abrupt

termination of the driver keeps the port locked and

therefore unavailable for subsequent print jobs. If

this situation occurred, please, try to release the MFP

port.
