SOURCE: have a cru fuse eror?
Your description is not clear. Replacing a fuse does not repairs the fuser. But if you replaced the whole fuser with a brand new one (not refurbished) then you have a bad power supply board. Unfortunately, you need to get a new copier.

I'm guessing that it''s remanufactured?
There is a small fuse on the front of the cartridge that may have not been replaced (or not installed at all). This is required to reset the toner unit - it basically blows at installation.
You can try this -it applies to another similar model, but may work for your as well to reset manually:
Press "Menu"....1934 (you may have to press "#" before the number??)
display will read something like "Tech mode"
Keep pressing "Menu" until displays "new cartridge"
Then press "yes", or "ok" or whatever applies to reset.
Please rate me
