Epson inkjet cartridges are cartridges that use technology called the ‘piezoelectric crystal’ method or technique, rather than other inkjet manufacturers who use an entirely different technology from the (easier to pronounce) ‘thermal’ type of printer.
The essence of the difference, and indeed the similarities, of the piezoelectric and the thermal methods differ only really in the different technologies used for the same purpose, namely getting the ink onto the paper in the right quantities and right colours. To be able to do this effectively the ink has to be forced down onto the paper.
To force the ink correctly down the miniscule nozzles Epson and the other main manufacturers in the world went their different scientific ways. Canon, Hewlett-Packard and Lexmark opted for the ‘steam type of method, whilst Epson developed new technology along the lines of electrifying crystals.
In the ‘thermal’ type of printer the cartridge will contain the necessary heating elements inside each ink cartridge to vaporise into a bubble. An electric current is used to fit in with the printer’s electric instructions which vaporise the ink, pushing it down the nozzle, whilst the remaining steam in the bubbles pushes the other unused inks back into place ready for the next signal. This is, of course, why it’s called a ‘bubble-jet’ printer, the bubbles being located above the nozzles.
Epson printer cartridges , on the other hand are based on a very different technology, which is that of the ‘piezoelectric’ crystal. In this case the method of forcing the ink onto the paper perfectly also uses electric currents, the major and important difference being that the piezoelectric method uses crystals which move upon electronic impulses, the unused ink is returned to the reservoir by a sort of electronic magnetic effect ready for use.
It has been found that this method does have distinct advantages over the other ‘big 3’ manufacturers in the variety of inks that can be used by this method, certainly this method is used by commercial and professional printers as they tend to give better results than the ‘thermal’ printers.
Epson printer cartridges , as you can see from the above semi ‘techno-burble’, have to provide a very full range of ink cartridges to suite all types of printing needs. The research undertaken to provide these different inks and cartridges to satisfy each individual’s requirements and needs is vast, and so therefore a vast number of different types of ink cartridges are available.
The catalogue of Epson printer cartridges shows the enormous range and it’s applicability to each specific printer. It is worth noting that Epson printer cartridges can be bought in many countries at a substantial discount, and that at the moment Epson undercuts manufacturers of ‘thermal’ types of inks. Naturally, you can see the whole range on the net.
