Hello, everyone!
Although the price of Canon IP2780 is cheap, it is very expensive to use. I bought one on August 21, 2010, and now (December 10, 2010) has replaced a black print head. Now the new print head is broken again, and the print head costs about 90 yuan, so it is very expensive. So I suggest everyone not to buy this machine.
