Summary: I will never buy another Canon printer. I've always had HP printers in the past and had good luck with both a laserjet and an inkjet. Then I got this piece of junk. Like other reviewers, I had problems with the ink cartridges (won't print if one is low) and the paper output tray.
Summary: I use my printer infrequently, so my first set of ink tanks lasted about 6 months. I replaced the PGI Black cartridge (one of the 5 that this printer uses) with an authentic Canon one which cost about $16. Now the printer won't print black at all.
Summary: I used this printer a few times after getting it, and it seemed OK. The quality was nice for what you pay, but there's something seriously wrong with the ink cartridges. A few weeks after getting the printer, I decided to print a few more pages. No such luck.
Summary: this printer is just a big headache. First problem: the printer won't work unless all ink cartridges have ink in them!! So if you use up, lets say, the magenta ink you can't print using the other ink tanks unless you replace the magenta ink.
Summary: We have had our Pixma IP4300 for just under a year now. For the first 3 months or so everything worked great. Then we started to get error messages related to a problem with the ink tanks. Specifically the cyan ink tank. We are now on our third replacement tank and the error has just popped again.
Summary: I bought this, within a month the print head went out. Canon replaced it. Now, I have had it over a year, and it has stopped working. It says:Document printing cannot be executed because the paper output tray is closed. But the paper output tray is open.
Summary: I bought this printer from Amazon after Consumer Reports tagged it as a "best buy". But unfortunately I must have gotten one of the rare lemons. The magenta ink cartridge did not work after only two printings. So I bought a new cartridge, and it still didn't work.
