For Intellifax 2820 (maybe others) Toner works fine, but when you remove old one from machine it removes both toner and drum, you have to remove old toner from drum, attach new toner to drum, then reinstall.
Trying to save a few dollars I ordered a toner cartridge through another vender and was very disappointed. Not only was it lower quality cartridge than the one I order through Monoprice it was the wrong one as well. Monoprice delivered a high quality cartridge as well as the right one. So much for trying to save few extra dollars, I should have went with Monoprice from the get-go.
We've come to rely on Monoprice for all sorts of items. We purchased some inkjet cartridges in the past, and had great success with them, so we decided to try laser toner. Monoprice has a great price and the toner works as it was intended. Thanks, Monoprice!
