I need some help in identifying the problem associated with an error code "50 Service."

The printer automatically begins a 05 SELF TEST after power on and then displays a "50 Service" code. Seeing that most 50 error codes are fuser related and I had never replaced the fuser or even serviced the printer before this, I assumed that the fuser was the issue. I ordered a maintenance kit and replaced it. It went through the 05 SELF TEST and 02 WARMING UP mode and then I heard a click. Now I still get the "50 Service" error code again. Turning the printer off for 15 minutes does not fix the problem.

This is not identified in my book or on your website. It must be more serious than just a fuser related issue.

Any Suggestions as to what a "50 Service" code means?

Thanks, GG**2
