HP laser parts: More on Cartridges and Printers

As many buyers know, HP laser parts and other printer accessories have come a long way since they first became available almost twenty years ago. Hewlett Packard's DeskJet printer was among the first available to the public and was priced at $1,000 in 1988. Today, you can get a basic HP Inkjet for $40.00 that prints both black and white and color, and prints up to 4800 x 1200 optimized dpi. Even the top-of-line wide format Inkjet printers run around $300.

If you are like most inkjet printer owners, you rarely look inside your printer. Normally, most people only open their printers when they have a paper jam or they think their HP ink cartridge is running low. But the ink cartridge is just one element of a pretty complex mechanism. At the heart of your HP Inkjet Printer is the print head, which houses the nozzles that are responsible for spraying the ink onto the paper. The print head and ink cartridges (print head assembly) are pushed back and forth across the page by the stepper motor and travels across a stabilizer bar.

Most inkjet printer manufacturers (including HP and Canon) use thermal bubble or what is also known as bubble jet technology in order to transfer ink to the page. In these printers, tiny resistors heat the printer ink to form bubbles. As these bubbles pop, ink is fired back onto the page. It is important that you understand this technology so as not allow your HP laser parts to cause problems with your equipment.

You see, if there is no ink in the chamber when the resistor turns up the heat, the nozzle assembly will quickly warp and break apart. If this occurs because the ink cartridge has not been refilled or replaced promptly, your equipment can become damaged. The damages can range from poor print quality (streaks or lines across the page, light or dark patches on the page) to some very serious and costly damage to your printer itself. It is very important that you check your HP laser parts regularly in order to avoid this from occurring.
