Possible Cause and Solution
• 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 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 will
be displayed.
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.
• 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.
Please 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 port while printing, the abrupt termina-
tion of the driver keeps the port locked and therefore unavailable for subsequent
print jobs. If this situation occurred, please, try to release the port.
Incompatibility between the PDF file and the Acrobat products.
Printing the PDF file as an image may enable the file to print. 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.
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.
