Printer has been out of ink because I just don't have the $68.00 to by the 5 cartridge pack of ink. Seen on e-bay a company in California selling a compatible 5 pack with chips for $10.80 and free shipping so I decided to give them a try. They arrived today, so I installed them, did the print tests and printed out a couple of things. They seem to work great. If they don't last as long as the Cannons I can buy 6 sets of these for the price of 1 set of the Cannons. Just so they don't damage the printer.
