| I use a Canon MultiPass C-5500. I print a lot of text, and replace or refill my cartridge once ever 2 -3 months. Through trial and error, I find that I save the most money by using the Canon cartridges and replacing the ink with an off-brand ink jet refill system. I have replace a full tank about 2, maybe 3, times, before I feel that the cartridge itself needs to be replaced. I experimented with different brands of "refurbished" cartridges, which are ink jet cartridges that have been refilled for you. Although the price is tempting, I don't think it is a bargain in the end. They are difficult to refill and they have already been used once or twice, who knows how many times. I find that most universal refill kits works, and that you don't have to buy a refill kit specially designated for the BC-20. I like Comp USA's, but I've used other ones to much satisfaction. I have used many printers over the years, form the wreaching sound of the dot-matric's to the silent but deadly effective laser's of today. I own a cannon bjc2000 for my home and it was a great price for the amount of quality features it has. The way to keep this product lasting is to use original cannon ink. Do not fall into the trap of those refill kits. Sure you'll save money, but at what cost? The cost is damage to your printer possibly from excessive thinning agent amounts. Well this is an awesome price for the amount of prints youll get out of the box! I use this as an everyday cartridge, and replace it with the BCI-21 (Color & Black) when I need to do color printing. It works great--lasts forever, and is easy to install in the printer. |
