Table 7-6. Numerical Printer Messages (continued) Control Panel Message Event Log Message Explanation Recommended Action 50.X FUSER ERROR A Fuser error has occurred. X Description: 1 = Low Fuser temperature 2 = Fuser warm up service 3 = High Fuser temperature 4 = Low/Bad line voltage. (Printer hooked up to UPS uninterruptible power supply) 5 = Inconsistent Fuser Turn the printer off, wait 20 minutes, and then turn the printer on. 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 J132-1 and J132-2. See Figure 7-4.
If it is not within the range of 200k Ω to 500k Ω, replace the Fuser. If there is no continuity between the Fuser connectors J143F (neutral) and J142F (hot) with the Fuser removed, replace the Fuser. If the problem is not related to the Fuser, replace the Engine Controller Board.
