Canon BCI-6 YELLOW Ink Cartridge - Compatible with MP760, MP750, MP780 Printers - High-Quality Replacement Ink for Home & Office Printing

Well, the other guys are all complaining about Amazon's shipping charge. Amazon's "free shipping for over $25" offer comes and goes, so if you see it in effect -- it is as of today (10/12/2005) -- grab whatever you need. As for buying the ink tanks, just buy all three colors in the set at the same time to qualify.Anyway, let me talk about the ink tanks themselves. The three "BCI-6" ink tanks work in the Canon Pixma iP3000 printer. (Maybe in other models as well, but I have the iP3000.) These are official Canon ink tanks so you'll know they'll work well. The number of prints you get heavily depends on your printing habit, e.g., what you print, how much you print, and at what quality you print.Using my usage as an example. I print at Normal Quality most of the time, and I print about 50% photos (at 200 or 300 dpi, depending on needs) and 50% web pages (e.g., flight confirmations, Hotmail messages, etc.). I don't print Word text documents much. I've run through 2 sets of ink tanks, and my very rough estimate is each set has lasted about 250-300 8.5"x11" sheets. Maybe more, but I don't wish to raise your expectations too much. Suffice it to say that of all the inkjet printers I've owned -- photo or not -- the iP3000 has a terrific ink capacity record. Of course, if you use one color more than the others, that particular ink tank (or ink tank combinations) will go out faster.(For your reference, a few months ago I read in a magazine review the the average per letter-size print cost of the iP3000 came out to around 12 cents per page on plain paper, one of the lowest average costs for inkjets. Not sure what settings they used in their tests or how much they paid for ink tanks, though.)In case you are interested... the new Canon iP4200 model employs a new formula of ink which supposedly will not fade for at least 30 years. My own take is, no matter how you print your photos -- even at professional photo labs -- a photo print will eventually fade if exposed to light. It's just a simple law of chemistry. So be sure to archive your digital photos on CDs or DVDs so 30 or 40 years from now, you can still print fresh copies and relive your treasured memories in their full colors.
