Nec NEC SuperScript 640

Suddenly printing black pages

I have an NEC 640 that has suddenly begun printing all black pages (including the diagnostic page). The manual says to change the toner cartridge, and I did, but that makes no difference. Does anyone know what the most likely problem is?
I THINK IT COULD BE THE CONTACTS ON THE DRUM UNIT
I WOULD CHECK THESE
