This does require some skill

Here are some new updated photos. After cleaning out the printhead and refilling it with ink we installed it back into the printer and it worked just like new. We will be testing this printhead to see how long it will work.

Why HP's Officejet Pro 8000 and 8500 940 printheads can fail

 

 

 

 

 

 

Printers using HP 940 cartridges should use a pigment ink for all colors including Black.

 

 2. Printers using HP 88 cartridges use a dye base ink for color and a pigment for Black.

 

 

Ink sludge build up from mixing different types of inks.

* Our new ink can break up this sludge.

Warning! Do not use a dye base ink in the HP Officejet Pro 8000, 8500 models they where designed for pigment ink.

Mixing different types of ink can cause ink sludge to build up and it will shut down the printhead.

This style of print engine has been around for almost 10 years. These printers use individual cartridges and printheads. We invented the first auto refill system for this type of print engine.

Update: We now have a tool that will clean and fill the print head.
