Summary: Another Lemon
Review: It worked fine initially but now it won't print at all. Seems to be related to the blank ink printer head being clogged. Tried to clean it but nothing worked. I guess you get what you pay for. I think Canon may have produced this product for obsolescense in less than a year. I won't buy another Canon product.Canon's customer support is less than zero for this product.

Summary: Well-documented clogging problems
Review: Based on much of what I read here as well as external reviews, I purchased an S520 from Amazon a little over a year ago. The performance has been decent, but I noticed several things which quickly became annoying: 1. Long cleaning cycle, which drained ink -- this occurred mainly during start ups or powering up. 2. Problems with the auto power-off Worst, after a period of about one month without use, I found that the black ink printer head had clogged. The cartridges were not run dry, nor did I use anything but original Canon ink. New cartridges did nothing, nor did repeated deep cleaning. I even used alcohol and Q-tips without success. After looking on-line, I learned that this is an identified fault with this model. Am about to try my luck with Canon, but don't expect much results. Caveat emptor!
