Our repair tool for HP 70, 72, 73, 88, 91, 761, 762, 771, 773, 774, and 940 print heads will prolong the life of your print heads. If you experience poor print quality and head cleaning, try this tool before purchasing a new and very expensive printhead!

This tool is intended for the following situations:

• A very clogged print head (with our head cleaner)
• A print head that does not work well because of air infiltration.

This tool works by replacing the ink that is in the printhead. The double funnel and the special syringe are attached to the printhead. It is necessary to fill the double funnel with ink of the appropriate colour. Next, by pulling on the special syringe, the ink will pass through the whole printhead and displace any air trapped inside.

The tool comes with detailed, easy to follow instructions with pictures. With these instructions, you will learn how to identify the specific cause of your printing problems and how to solve them with the tool.
