Tips for the  HP LaserJet M601, M603, M602 50.10 Fuser Error  

1. Turn the power off then back on. Heck, this is a low temperature reading. They happen from time to time. Once in a while is exceptable, by that I mean once or twice a year. If you see them on a more frequent occurrence and they start happening more often then you probably have a more serious problem and fuser replacement isn’t too far down the road.

2. Check the power source. Make sure it is plugged straight into a wall outlet. Make sure you do not have it plugged in a power strip or battery back up. Your printer requires lots of power to  heat up the fusing unit which it does rather quickly. You need to make sure nothing is getting in its way of getting the power required.

3. If the machine was outside in cold temperatures then make sure you allow a few hours to get the insides to room temperature.

4. Reseat the fusing assembly.

5. Replace the fusing assembly.
