I have installed a xerox workcentre 3210 multi-function printer for a dental practice.
Some prints work, but summary reports invariably crash with 0x50. The machine is a sony vaio with win7 home. The xerox driver is correctly win 7 x64
Another xp-pro machine in the practice with the 32 bit xerox driver works correctly.
I have downloaded the latest 64bit win7 driver from xerox (dated 04-16-2010)
The xerox site advises firmware version 220.127.116.11, but the printer has 2.50.00.99
The connection is by tcpip - I noted on the webpage for the printer
The dental software provider blames the print driver, while the supplier blames the dental software.
