I have had this all in one machine for about 3 years so I am pretty familiar with it. It has frequent paper jams no matter how careful you are. These jams are cumbersome to clear as you need easy physical and visual access to the back of the machine. If there is a tiny shred of torn paper in there, good luck trying to find it. The two sided printing function most always ends up in a paper jam so I would consider that function useless. The ink cartridges do not last long and they are very expensive to replace. I rarely use the color printing yet they need frequent replacing. When one goes, you have to replace them all. The scanner function works well. Basically, this is a poorly made machine that is expensive to maintain.
