Description: Emulation Error
Causes: A failure within the download emulation CRC which is programmed into the RIP board. To resolve the problem, a servicer may disable the download emulation by entering the Configuration Menu and set the Download Emulation to "Disabled." The download emulation may be reinstalled at that point. If the problem persists, the download emulator may be faulty and should be replaced.
Code: 975

Description: Duplex Comm.
Causes: A communication error occurred between the base printer and the optional duplex unit. Check the installation of the duplex unit, particularly the electrical connection. If installed correctly, remove the duplex unit to see if the error message goes away after rebooting. If the problem goes away, replace the duplex unit. If the problem persists, replace the RIP board.
