huge problem

when changing ink cartridges.
First they take very little time. Then the printer does not recognize the cartridge when you change. even with original cartridges.
I bought this printer to print some copies and some home. I spend a lot of time when changing cartridges. it gives me each time a cold sweat and I really want to throw it out the window. it's really very poorly explained and operation is complex.
I did not redeem Epson. this is my 3rd printer that mark but the last.
