It was working perfectly a few weeks ago but then it started jamming every time I tried to print. It has a (nearly) new toner cartridge.
I don't know the page count but I bought it new about 15 years ago and didn't use it very often (usually no more than a few pages per week), so you can estimate the page count from that.
I will package it in the box of the new printer I just bought, which is the exact same size and shape as the old one. It's a huge, sturdy box with large molded Styrofoam inserts to protect the printer during transit.
