4520-xxx Setting Configuration ID The configuration ID is used to communicate information about certain areas of the printer that cannot be determined using hardware sensors. The Configuration ID is originally set at the factory when the printer is manufactured, however it requires resetting whenever you replace the engine board and can be set on the operator panel. However the Configuration ID is the only diagnostic function displayed until a valid ID is entered. To set the Configuration ID: 1. Enter the Diagnostic mode. 2. Select Configuration ID from the Printer Setup menu. • The current ID displays on the screen. The Configuration ID is on a label located inside the printer. The label is attached to the top front cover hinge assembly and is visible when the top front cover is open. • The leftmost digit blinks indicating that it is the first digit to be changed. 3. To change the value, press either Menu until the value you want is reached. Press Select to move to the next digit, or press Select again to skip a digit. Change each digit as required. When the last digit is changed, press Select to validate the Configuration ID. If the ID is invalid then "INVALID ID" message displays on Line 2 before the ID redisplays. You have to reenter the Configuration ID until a valid ID is verified. If the ID is valid then the ID is saved in NVRAM and the printer automatically PORs to activate the new setting. Note: When the printer PORs it does so in the normal mode. 3-20 Service Manual
