I started my computer life with a Canon printer and ink and have had perfect performance from both--except for the time I bought a store brand ink instead of the Canon brand. The store brand not only leaked but pretty much ruined the printer. To have it cleaned was nearly the cost of a new printer. I bought a new printer. This is my third, and it scans and copies and prints quickly and really well. This ink lasts "forever" when I print with Draft, which is most of the time with text. For color photos, it does a fine job even with Draft, but with the next two higher, sharper settings, it's absolutely perfect!
I'm always satisfied with the results I receive when using any Canon ink cartridge. I've never had any problem. Well, maybe the only problem would be when any cartridge (color or black) begins to empty. Then, of course, the text or image I've printed start to look somewhat faded. . . white lines begin to appear through the text or image. It basically means, it's time to buy more cartridges! It seems the cartridges last a pretty long time with still great results.
I do wonder about whether I should try and refill a cartridge. Using a different Canon printer, I was able to do this ten years ago or so. More recently, one time I didn't have good luck doing this--refilling a cartridge & using it again. Is it too much to expect a good result with my newer Canon printer?
We use these sizes and the larger 50/51's in our Cannon printers. They cost too much and don't last long enough. The printer companies need to listen to the customers! Your printers are not lasting and your ink cartridges are too small and too expensive. You are gradually driving away my business! We avoid as much printing as possible now. The post office found out the hard way when they priced themselves out of business and stopped looking after their customers. Printer and cell phone companies are next.
