These cartridges look similar to a big "L." They were used in old desktops (about 15 years ago), plotters, and industrial machines. Recently, the TIJ 2.5 revolution made these cartridges very popular in industrial printing, mail addressing, hand-held printing, and automated coding.

How to put ink in
All these cartridges are refilled the same way. For each slim one, there is a metal ball on the bottom. You will push the ball inside and then fill up the cartridge. For the fat one, you will open from the top and add ink. Then, you need to seal it (fat ones don't need seals) and suck the air out of it. You will need a narrow (green) priming tool for the 40 or45 and a wide (blue) priming tool for the wide-body, such as the 78.
What kind of ink to use
The difference will be the ink inside. Please read carefully for what type of ink will be needed for your particular application. The ink included here is generally for desktop printers. For example, the desktop ink will burn the printhead if it is used in a high-frequency machine such as a Kirk Rudy.
How to print
These cartridges don't have ink monitors and can print forever. However, if you have a cartridge that's been re-branded, which means a 3rd party chip is glued to the cartridge, it usually can't be refilled. The 3rd party chip will prevent you from refilling the cartridge.
We put some sponge-models here, such as HP 78, which are not true spring-backs, but they are used with spring-backs together in the plotters. Also, they use similar types of priming tools.
