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.

There are two type of ink cartridges used on the Continuous Ink Supply Systems and refillable cartridges

The one with the " out of ink sensor " also has a constant pump that helps maintain pressure to the printhead. This is the type we use for both out ink system or refillable cartridges.

 

 

 

The second one is used by many companies who are selling a cis - continuous ink system or refillable cartridges. There are many flaws with this style.

This design should not be used on the Officejet Pro 8500 or 8000 it is out dated.

 

 

 

Our new oversize refillable cartridges are great for high volume printing never remove the cartridges for refilling.

 

To remove the chip cap off the HP cartridges just score the label on both sides of the HP cartridge. Then you just snap it off. No cutting off the chip with a sharp knife. This could damage the chip.

 

 

 

 

 

 

 

 

 

 

Now snap the chip cap onto our cartridges.

Simple and Easy!

 

 

 

 

We supply this purge tool with all our refill kits and ink supply systems.

It is a good practice to purge air from the ink lines of the printer from time to time. We also use this tool to clean the lines of any clog because the customer used the wrong ink.
