The error on the printer is coused by the speed and ammount of print job is has
to swallow. if i print a file with the same amount of pages its not really a
problem. I already updated the firmware to the newest version and even contacted
Xerox for help. but they said the machines are just not made to handle printer
tasks at the speed i send them.
