50.4 PRINTER ERROR
A problem exists with the customer’s line voltage.
1. Remove the printer from any UPS supplies, additional power supplies, or power strips.
2. Plug the printer into a wall outlet and see if this resolves the problem.
3. If the printer is already plugged into a wall outlet, try another power source in the building that is independent of the one currently being used.
4. The line voltage and current source at the printer location might need to be inspected to ensure that it meets the printer’s electrical specifications.
50.X FUSER ERROR
A fuser error has occurred.
1. Turn the printer off, wait 10 minutes, and then turn the printer on.
2. If the message persists, reseat the fuser. If that does not work, replace the fuser. To check the fuser, turn the printer off and remove the fuser. Measure the resistance between the fuser connectors. If it is not within the proper range, replace the fuser. If there is not continuity between the fuser connectors neutral and hot with the fuser removed, replace the fuser. If the problem is not related to the fuser, replace the engine controller board.
