Before the host machine (print engine) is shut down to insert the Open I/F (Interface) PCB, COPIER>OPTION>INT-FACE>IMG-CONT must be set to establish IP address communication automatically between the host machine and server (Fiery). Note: otherwise the machine locks up, or throws an communication Error Code when it boots up and detects an unidentified PCB. Select the correct setting for COPIER>OPTION>INT-FACE>IMG-CONT.
