Two Key Components In Every Printer Ink Cartridge

2010-07-30

Printer ink cartridges are highly precise instruments that allow elaborate printing on even the most basic home printer. While the printer cartridge components may seem simple, consisting of the ink reservoir, a silicon circuit and the flexible strip containing the contact pads and ink nozzles, it is actually a complex system that requires exacting calibration to work correctly.

The most straightforward of the printer cartridge components is the ink reservoir. It is made of a foil pocket that forms a vacuum to keep the ink from dripping out. The ink serves a dual role of printing the text and images desired, but also of cooling the silicone circuit which is housed inside the ink reservoir.

Printer ink cartridges are powered by the silicone circuit. When electrical current passes through this circuit, it pulls the ink in and activates the hundreds of microscopic nozzles on the flexible strip. Along the sides of the circuit are tiny moving groves that serve as both the guide telling the ink where to go and as the channel that moves the ink from the greater reservoir to the nozzle where it is sprayed onto the page.

The flexible strip contains the contact pads that communicate with the printer and pass the electrical current to the silicone circuit. It also has hundreds of tiny nozzles that squirt the ink onto the page. The calibration or alignment of the nozzles is exacting, allowing them to act in concert to create one solid image. The flexible strip connects to the silicone circuit at one end and to the printer's contacts at the other. As such it serves as the point of entry for data that tells the printer cartridge components how to produce the desired result, and the point of egress where the ink meets the paper producing the final printed output.

When printer ink cartridges work properly, the various printer cartridge components work in unison to create text and images to exacting standards. The ink reservoir must have ink and maintain its vacuum to function properly. Many ink replacement kits fail because the vacuum of the ink reservoir is compromised. The silicone circuit is the engine that drives the printer ink cartridge, carrying the load of electrical current and moving the ink along to be used in printing the image. The flexible strip must communicate to the printer via the brassy contact pads and then apply the ink to the page through its hundreds of nozzles. This system operates cleanly and precisely although it is simple in functionality and complex in its design. These three printer cartridge components make up the working elements of all standard printer ink cartridges.
