How to Refill Ink for an HP C4280
The HP C4280 printer uses the HP No. 74 (black) and HP No. 75 (color) ink cartridges. These cartridges cost $25 each to replace, as of October 2010. If you replace both of these cartridges five times a year, that is $250 on printing costs alone. You can reduce your printing costs dramatically by refilling these cartridges instead of replacing them. A refill kit will cost you about $20 and can be reused up to six times. That is over $200 in savings for the year. Not only will refilling the cartridges keep extra money in your wallet, but it helps reduce unnecessary waste in landfills. These cartridges are constructed from non-biodegradable materials that can take up to 100 years to degrade. Thousands of ink cartridges pile up in our landfills each day.
