Xerox Workcenter 7556 printing issue

I have recently purchased Xerox Workcenter 7556 and can not seem to get it working.

I am certain we have the correct driver and things are being sent to the printer but are failing to print.  I have manage to print something off notepad but it i try and print something with an image it says the following:-

ERROR:ioerror

OFFENDING COMMAND: image

STACK:

-dictionary-

Does anyone have any suggestions?

Thanks
