Re: How do I re-set my refillable ink cartridges?
Yes, you have to use a "chip resetter" which resets the ink level information on the chip back to "full". You can buy the chip resetter tool online. Just type Ink cartridge chip resetter into Google Search and you'll get loads of results back.
The chip resetter is not universal. You must make sure it's compatible with your printer model before ordering. The vendors' websites will show you which resetter is for which models.
Unless you are a heavy user of printer ink though, I don't consider it worth the hassle. I certainly wouldn't recommend refilling carts with generic ink if you print photographs and demand high quality results. I print photos regularly and once tried refill ink for the job. The results compared to genuine Canon inks were horrendous so I definitely won't be doing that again.
