Computers are currently a necessity to any individual or business. With the onset of this device, came a whole lot list of appliances that this device would possibly need in order to meet the user's requirements. The device in question here is the printer. Almost all offices and households currently have printers to aid in reproducing documents.

As with the DVD and television, the printer also requires its own set of equipment's i.e. toner cartridge. Printers vary in shape, color, size and length hence do their cartridges so a proper cartridge should be selected that functions properly with the printer. There are different manufactures of cartridges in the market currently which makes the consumer have a wide variety of brands they can chose from.

Before one can proceed to buy a toner cartridge, the model and make of the printer must be considered. The same make of a printer may utilize different cartridges i.e. there is a variation between 7400 toner, 9600 toner , 7050 toner and ce320a .

Components of ...
... a toner cartridge and their functions.

Before we compare the different types of cartridges, we are going to have a look at the internal structure of a laserjet toner cartridge and how it works. A cartridge is a complex device that has dozens of parts, separate parts and multiple nodes. This device can be divided into these major parts i.e.

Toner- used to create the images.

Body - which includes parts like the universal chip, magnetic roller sleeve, sealing, recovery and doctor blade, OPC, drum etc.

Fuser assembly - heats and firmly presses the toner to the paper.

Among the parts of the cartridge, there is the Organic Photo Conductor (OPC). This is the most advanced product in toner cartridges hence the most expensive. OPC part has the greatest impact on quality of prints. It comprises of an aluminum cylinder enclosed in a photosensitive layer. The photosensitive layer has different structures depending on the type of printer and cartridge, also varying in gears and sizes to achieve a certain rotation.

The primary charge roller (PCR) is an axle made from metal that is enclosed in a shell. This part has varying structures of the enclosed rubber layer. It performs the operation of charging a photo conductor with negative charges, these negative charges are then put onto the paper. In some printers it also acts as a caretaker since it cleans remnants of toners from the photoconductor.

Using contaminated paper can damage the photo conductor so it is advisable to store toner cartridges in a package. The printer's laser beam spreads negative electrostatic images to the positively charged drum only reversing the polarity of charges where the image should be. The drum roller now has the negatively charges image and proceeds to roll on the positive toner picking the image from the toner only. This works by the law of physics in that opposite charges attract. The drum is responsible in forming an image hence the quality of a print will depend on its condition.
