Like printers, printer cartridges have also gone under various changes. Apparently, printer cartridges are reservoirs of the ink. However, their structure can be very complicated. If you are considering refill your inkjet cartridge then it is very important for you to know your inkjet cartridge. Here is a general introduction to an inkjet cartridge…

The part to you need to look at is the print head. The print head is the engine of your printer. This print head may or may not be located inside the cartridge. It is a metal part with hundreds of tiny, delicate nozzle assemblies. Each nozzle assembly consists of an ink chamber, a resistor that controls the flow of ink and walls that guide the ink to the nozzle plate with a hole from which ink is sprayed onto the printer paper.

After each time a nozzle empties its quota of ink, a new supply of printer ink is automatically drawn into its chamber, to be ready for the next time. When the printer gets command to print, the copper circuits on the end of the ink cartridge activates the nozzle’s resistor. The resistor then heats the nozzle’s ink supply just enough to cause it to expand and to force a drop of ink through the nozzle onto the printer paper. The resistor can reach a temperature of hundreds of degrees very quickly! If there is no ink in the chamber when the resistor turns up the heat, the nozzle assembly will quickly warp and break apart as it is very delicate.
Here the ink also does another job. The ink which flows through each nozzle assembly functions as a lubricant and coolant for the nozzle so does not get damaged.

It is very important never to attempt to print with an empty ink cartridge. The print head can burn out if the ink cartridge is not refilled or replaced promptly. The effect of the damage may range from poor print quality that will show up in the form of lines across the print page, blurring and light or dark patches on the page. Eventually, this can be fatal for the printer.

Unfortunately, there is not way to know the status of the ink in the cartridge. To avoid this errors, what you can do is to replenish the If doubt, top off your cartridges frequently from your refill pack.

Refilling all types of printers is not easy. This problem is occurring with some recent models of HP. HP has dramatically changed design of their black inkjet cartridges for the DeskJet 500 & 600 series. This step was to taken mainly to curb refilling. The inkjet cartridges have gone under many changes like introduction of air bladders, constantly changing maze or venting assemblies at the bottom and logic to change the signals to the resistor jets on the multiple reinstallation of the cartridge. The color cartridges also went under some changes. Here, the cartridge must be refilled before air locks occur, particularly in the yellow chamber.
