Problem with an HP 5110 printer/scanner/fax/copier working with Xerox DocuMate 510 scanner. OS Win XP Media Center on an HP Media Ctr PC. Problem: Printer will not print. All other functions of the AIO work properly as does the Xerox scanner. When I try to print to the HP5110 it returns a "System Error - The document cannot be printed due to a system error. Try printing again. If unsuccessful, restart Windows and try printing again." Neither of these options resolves the problem. Neither Xerox nor HP tech support were able to help. I have uninstalled and reinstalled each of these devices numerous times. Printer worked prior to installing the Xerox scanner. Device Manager does not list any problems. Drivers for both devices appear to be from Windows. The updated drivers from HP were downloaded and "installed" but the driver listed in device manager is still from 2001. HP tech support could not help after 3 HOURS on the phone (both printer and system tech support). They say the problem is with the Xerox scanner. Xerox tech support says the problem is with the system not their scanner. Does anyone know how to fix this problem?
