Hello, we're printing on a C1 with a Fiery-Rip. Sometimes the printer stuck with an error E00670-0880. The Rip send the printing-job completely to the C1, but in the systemmonitor the job is listed with 0k. Only a restart of the printer after the E00670-0880 error let the print come out. A few weeks ago we had a dhcp-problem on our servers. The support has updated the C1 and the Fiery. Nothing changes. Canon hasn't documented this error Best regards Andreas
