My guess is that you have either not put the cartridge back in correctly
or you have not assembled the cartridge correctly after refilling it.

Ditto. I've had an ML2010 for a few years: cheap and cheerful.

I always have trouble putting the cartridge back in: it has to go in a
long way (I appreciate that yours is a different model btw) and there's
a definite clunk when it's in properly. I suggest you take it out and
slide it back in again (and again and again if necessary) until it has
definitely clunked into place. Also check the paper feed -- no sheet
stuck in there is there?
