m476 printer 54.2100 and 54.2500

[Cirrus]

I have a hp m476 that is stopping on each print. The paper stops a couple of inches out of the fuser every time. The error log shows a 54.2100 beam detect error or a 54.2500 top of page error. Both of the sensors in the fuser area are working correctly. Can anyone tell me which sensor triggers these codes?

Thank you.

Possibly a fautly laser scanner or a DC controller problem from what I can find.
