hp4730 Drum phase sensor out of range

[Guest]

I have an Hp 4730mfp (Q7520A) that is getting the following errors. I've replaced the fuser and it made no difference. It's intermittent but I occurs almost daily. I'm not sure which color 54.08 is referring to. Once I know what is common for a fix for "drum phase sensor out of range"? Any tips?
