Refill an inkjet cartridge by either taking it to a qualified inkjet cartridge refill business, such as Costco or Rapid Refill, or purchasing your own ink refill kit from Walmart or another retailer. Inkjet cartridge refill businesses may only service certain cartridge brands, so check yours before drop-off.
Refill your inkjet cartridges at Costco by taking the cartridges to a store and using the company's automated refill machine. HP, Canon, Epson, Lexmark and Dell are among the printer brands that Costco provides cartridge refills for. The automated refill stations feature DeepFill technology. Rapid Refill provides new refill deliveries rather than refilling old cartridges. Cartridge deliveries are available from Rapid Refill stores for printer brands such as Canon and Dell.
Refill an inkjet cartridge on your own by purchasing an inkjet refill kit from Walmart. On Walmart.com, type "ink refill kit" into the website's search engine. As of 2016, options include the LD color ink refill kit for a Canon CLI-241 or CLI-241XL cartridge and the LD color ink refill kit for a Hewlett Packard C8766WN cartridge. For each of these products, use the manual, screw tool, injection needle and gloves that come with the kit to manually refill your cartridge.
