Query: terrible product

I bought 2 of these things to insure that I could use the same catridges. First, had to install about 6 times to get them to work, Next, one stopped scanning, Then it produced a light patch about 1 inch wide on the copy and scan functions. The other, after 6 months, printed a 1 inch wide black band on the copies and scans. Both did produce good photos from camera, but the procedures necessary seemed overly complicated, and the program for storing them on the computer was a bear to deal with, Instructions for use are almost uselss. These were the 5th and 6th printers from HP I have bought. No more, trying Canon.
