Lousy Machine will give you nervous breakdown

It very frequently says that the ink is empty and when you look at the window on the cartridge you see that there is plenty of ink still in it. But since absolutely all functions, even functions such as scanning that do not need ink, are blocked when the machine says that there is no ink, then you have to bite the bullet and put a new and very expensive cartridge (70$ for the set of 5) in it.
The machine takes several pages of paper at a time very often and shreds envelopes. Scanning under 1Mb/3 pages is not possible.
