If you want to save money from your printing expenses, then try refilling your run out Inkjet Cartridges. This will not only save your money, but will also save our environment. But, many refill attempts are blocked by clogged print head. So, when refilling cartridges, they should be refilled right before the ink is almost finished. The longer a cartridge remains inside the printer, the more likely the ink will dry inside the print head and cause blockage. If your print head becomes clogged, use a wet towel dipped in alcohol and gently cleans off the print head surface.

The HP Cartridge does not contain much ink. This cartridge contains a meager amount of 5ml of ink, and will run out quickly. If you do printing more than 100-200 pages per quarter, it would be wise to avoid printers that use this cartridge.
