Error:

50.2 fuser warm-up service

Error Description:

A fuser error has occurred

Solution:

1. Turn the printer off for a minimum of 20 minutes to clear the error. 2. For 50.4 errors, move the printer to another power source and disconnect it from any UPS supply. 3. Reseat the fuser. 4. Turn the power off and remove the fuser. Check the continuity between connectors J1307-1 (callout 1) and J1307-2 (callout 2). If the resistance is not in the range of 1 to 2.5 MΩ, then replace the fuser. 5. Check continuity between connectors J1308-3 (callout 3) and J1308-1 (callout 4) with the fuser removed. If no continuity exists, replace the fuser. 6. If the problem persists, replace the power supply, and then replace the dc controller, if necessary.
