Brother IntelliFAX 1820C Plain Paper Inkjet Fax

This machine is not worth a penny. It was purchased less than 6 months ago and it has given us nothing but problems. It states ink cartridges are empty, but they are not. And every time we change one here, the cartridge doesn't want to align so then it prints about every other line for incoming faxes. We have cleaned the cartridges, we have bought brand new cartridges, and nothing works. It is a worthless piece of machinery.
