I have a P1500 laser printer with the following light error codes:  all lights are flashing,  secondary codes are: 'ready' and 'Error' flashing and then the 'toner low' flashing. 

This indicates fuser problems.  I took the fuser apart to remove melted transparancies.  I checked the lamp and it has continuity.  There are no visible breaks while doing a visual check. 

Has anyone had a similar experience with this printer?
