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:

Can’t scan via Gimp

• Check if Gimp Front-end has “Xsane:Device dialog..” on the

Front-end.

“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

Please avoid changing print job parameters (via SLPR utility,

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.
