Have had my MP600 for 7 years. Great machine until 2 days ago when I got the "U052" code. Followed the instructions to clean the print head, but no such luck. The printer would not even clean the print head. Was hoping this would be the last printer I had to buy, so thinking this, I have extra ink cartridges on hand, which, by the way, are not inexpensive. Prior to this printer, I have had Brother, Epson and HP. Any recommendations?
