Printing, scanning is great. Copying is slow - for the unit is not really meant for it - for emergency copying only). But the main problem is the ink. The colored inks goes low even you print only in black. If one cartridge goes out of ink, the machine is useless. It is "a must" to replace it. Using all black cartridges does not do the trick. It will give a message something like "not compatible color cartridge". I remember that I had a canon before (12 years ago) and I had the same problem - the ink. That's the catch on why it's cheap. Canon should work on this area. Ink problem.
