Over the past three years I have had three inkjet printers All have been Canon who are arguably judged to be the best in this category. With the first one (Pixma-IP2000) , after a while, I used a local replacement company (Ink On The Run) to refill my 6 cartridges.

On printing, the colors ran together, even on top quality printing paper and the result was disaterous. I decided to continue use of the cartridges and just print day-to-day mundane things. Within a week, the printer's inkjets became totally blocked up and too it to a Canon repair business. As the printer was a week out of warranty, I was told the cost of repairs was greater than the price of a new printer. I was also warned about using inferior products and that by using them, would invalidate any warranty as well.
I gave the owner of "Ink On The Run" a real spray and he said there was nothing at all wrong with his product, but just an old machine. Right!
I then purchased a new Canon Pixma-IP4000D printer. The cartridges ran out after about 8 weeks and had to replace most of them. I wondered about using compatible replacement cartridges again and went to another business well advertised on television, Cartridgeworld. On my first print, the colors once again ran together like you wouldnt believe. I then decided to experiment and continued use to see if the inkjets wouls again clog up. Within 3 weeks of use, the inkjets were again blocked up on a new machine only 11 weeks old. This as all but one of my original cartridges still had some ink left in them, I then put them back in, purchased a new Black cartridge, inserted it and went back to another authorized repair dealer. I produced my warranty and the printer was replaced free of charge as the amount of damage done in such a short time was considerable. When they phoned me, they were out of that model and I was given a brand new Pixma IP6000D printer. This printer has serviced me wonderfully for the past 18 months.
I would NEVER consider buying cheaper, half-price replacement cartridges ever again. I know that new company manufactured cartridges are much more expensive, but at least they give a more than satisfactory result. Also, should there be a maintenance problem, then it will be covered under the warranty conditions (providing you don't use incompatible cartidges).
I am an IT professional and I know what I am talking about. Hopefully, all of you wonderful readers out there will heed my advice. If you don't, then proceed and prepare yourself for the consequences.
