These elongated refillable cartridges can hold 100ml of black or 70ml of color ink each, for around 3500 pages between refills (at 5% coverage). Refilling is easy thanks to the easy-to-remove plugs. Just remove the plug, inject ink, and put the plug back in.
Since the cartridges are bigger than the originals, the door will have to detached. This is easy to do and in no way damages the door. However, you will need to depress the printer's door sensor with a long, thin item. A brown plastic coffee stirring stick works great!
These cartridges come with the most recent auto-reset chips. You can reset the displayed ink level at any time by simply removing and reinstalling the cartridge.
