To Smoking Joe,
The third party vendor I used is
www.bulkinkjetcarts.com--which will get you to their web site, They were reviewed on nifty stuff forums, I found them to be very easy to deal with, they have a toll free telephone number, and I had zero problems with their cartridges. You may experience a slight color shift ajustable in software-----and by no means are they the only good vendor of cheap pre-filled cartriges. You might also want to check out
www.alotofthings.com or any of the other good vendors listed on the nifty stuff forums.---but for the bulkinkjetcarts review look to the six plus review by JV on same forum.--------------I am somewhat reluctant to endorse a vendor------but why buy a pig in the poke or risk getting a bad vendor---so get opinions of those who have tried that vendor before you buy is the key.
In terms of refill ink I will say there are three highly respected inks for Canon printers---MIS, forumalabs, and a fairly new outfit called hobbicolors. I decided to get a five color refill kit from hobbicolors--------which runs $21.95 on ebay.just type hobbicolors on the ebay search bar. The chief charm of the hobbicolors kit is that it comes with a syringe, ink, and five empty cartridges with a screw seal. Most other refill kits make you drill out some pre-used cartridge and then leave the user to find some way to effect a seal. And how to seal the ink inlet hole the home refiller must have is another hotly debated subject------but I favor a #8 stainless steel pan head screw with a tight fitting O-ring on the depleted Canon cartridges I used to get a spare set in addition to my five hobbicolors cartridges.
But by all means check other refill inks-------MIS can be found at
www.inksupply.com and the alotofthings.com site is one site that does vend forulalabs ink. --and also prefilled cartrdiges and blanks---the one mistake to avoid in refilling is to get a generic kit for all printers--if you have a canon printer get inks specifically made for a Canon printer--if you have a hp printer get inks for that model of HP's--etc.
But refilling your own is the way to go for huge savings----and dirt cheap printing----but my choices
in vendors need not be your choices---lots of good vendors out there---lot of bad vendors out there.
So get a second, third, and fifth opinion. But bottom line, and in my opinion, the Canon BCI-3&6 cartridge line is super easy to refill. And you can easily save better than 15x over OEM---and more than double that if you order inks in large quanities.
