Additional Tips for this Error

1. I’m not exactly sure why they have steps one and two. My guess would be to reset any values that have gotten messed up like paper settings or fuser temps.

2. like any fuser error the first thing is to turn the machine off then back on.

3. Since this is a warm up error, plug the machine straight into a wall outlet to verify it is getting proper voltage.

4. Remove the fusing unit and check the thermal fuse and lamps for continuity.

5. Check the thermistor surface and clean off a debris.

6. Replace the fusing assembly.
