Many reviews here complain of high ink consumption. Just because the printer 'nags' you that the ink is low, it DOES NOT mean that the ink cartridge is empty. By all means, keep a full set of cartridges handy, (I order when I get the first 'low ink' warning), but DO NOT REPLACE THE INK CARTRIDGE YET. Wait until the printer tells you that the ink cartridge is EMPTY. Even when the printer does tell you an cartridge is empty, you can still print a few more pages by pressing OK on the printer to ignore the warning because the printhead itself holds a LOT of ink. Using this method, in nearly a year of frequent use, printing photos, web pages, and lots of letter-size posters on card stock, as well as letters and envelopes, I've never had anything not print correctly because the ink actually ran out before I replaced it. I NEED a printer with both tray for letter paper AND a rear-feed for envelopes, card stock and photo paper. The newer models without a rear feed just don't meet my needs.
