I have a very temperamental iP8720. Currently, I am receiving error code 1411 (unrecognized ink). However, all the ink lamps are illuminated. I have replaced each one when all were full. Not only is it wasteful, it is expensive to replace the ink when there is plenty of ink left. I have also unplugged the printer. Any other suggestions? It seems ridiculous that a printer I purchased for $25 from a charity fundraiser is more reliable than my Canon. I'd rather not have an expensive paperweight.
