Inkjet Cartridges - How Do They Work ?

By Andrew James on 1 July 2013 (No comments - click here to comment)
An inkjet printer contains an inkjet cartridge and a print head which facilitates the printing process. This type of cartridge is replaceable because all the ink is normally used up during printing. The cartridge is normally refilled from time to time for smooth printing. An inkjet cartridge is a special component of an inkjet printer because it facilitates stores the ink that is used in the printing process. 
An electronic chip is used to facilitate communication between the printer and the ink cartridge. There are other electronic contacts that are normally added by manufacturers to ensure that the printer communicates with the cartridge in the best way possible. An ink cartridge can be partitioned into separate ink reservoirs depending on the needs of the user. The majority of inkjet printers are designed in such a way that the inkjets operate using a thermal mechanism.
Ink reservoirs in an inkjet cartridge are normally connected to a heating element which initiates the thermal mechanism. The heating element can be a resistor or a metal plate that is a good conductor of heat. The printing process begins when the printer gives a signal to the heating element. A very small quantity of current then flows through the heating element in the ink reservoir making it warm. The ink in the cartridge reservoir then vaporizes as a result of the thermal effect of the heating element. The steam bubble that is generated by this effect is then forced onto the paper through the cartridge nozzle. The ink vapor comes out of the ink cartridge nozzle as an ink droplet. This is a very fast process and it does not take even a millisecond to for it to come to an end.
 The level of ink in an inkjet cartridge should be checked from time to time to ensure that it does not become very low. An inkjet printer with a very low level of ink can not facilitate the smooth flow of ink. The level of ink in an inkjet cartridge should always be at the recommend level to prevent it from drying at the print head. The smooth flow of ink in an inkjet printer therefore depends on the level of ink in the inkjet cartridge. Users are advised to clean the print head of an inkjet printer on a regular basis to remove the dried ink. 
Luke warm water and isopropyl alcohol are very effective in removing dried ink from the print head. Luke warm water is used in most cases because isopropyl alcohol can damage the print head when it not used in an appropriate manner. The print head of an inkjet printer can also be damaged when the ink supply runs out. The heating element can end up burning out if there is no ink to act as a coolant. This is the reason why the ink cartridge should be refilled as soon as the ink level starts to run low. A piezoelectric crystal is also used a heating element in some inkjet printers.
