Laser cartridge, Ink cartridge and Ink tank

When it comes to printing, quality, quantity, and clarity are also important, so understanding the difference between laser cartridges, ink cartridges, and ink tanks is important to choose the right option based on your needs.

Laser Cartridge: A laser cartridge, also known as a toner cartridge, comprises several components, typically including the PCR, Drum, Wiper Blade, and Doctor Blade, each serving distinct functions. Should any of these components become damaged, the print quality may suffer accordingly.

At this juncture, a brief pause typically occurs as the corona wire undergoes heating to prepare for transferring its positive static charge to the drum.

As the drum, typically a coated metal cylinder, commences its rotation, it uniformly receives a positive charge over its entire surface. In certain printers, each color—cyan, magenta, yellow, and black—may have its drum.

The laser is then activated, emitting beams that bounce off a series of mirrors, eventually landing on the surface of the drum(s), imprinting the print's shape through an opposing negative electrical charge. Adjacent to the drum(s), the toner cartridge and hopper gradually release positively charged carbon toner particles onto the rotating drum.

These particles are attracted to areas of negative charge, leaving positively charged regions on the drum untouched. Subsequently, the transfer belt guides the paper through the printer, endowing it with a positive charge.

As the paper traverses past the drum, the negatively charged toner adheres to the page, forming the desired print shape.

Ink Cartridge: Most printers typically employ two cartridges: one for color and one for black ink. Each cartridge contains a total of 3 ink colors: Cyan, Magenta, and Yellow, which combine to produce a spectrum of colors. The black cartridge holds 10 ml of ink, while the color cartridge contains 3 ml each of Cyan, Magenta, and Yellow ink.

The printing process in inkjet printers is intricate, with the printhead playing a pivotal role. This component comprises around thirty nozzles, channels through which ink and heat flow, generating the necessary vibrations for ink ejection. It's important to note that various techniques are employed in this process. In some printers, a heating element is utilized to heat the ink within the nozzle, causing it to boil and create a bubble that expands, acting as a lever to propel the ink outward.

Ink Tank: People buy a printer and it also comes with a cartridge, but it wears out after some time and is very expensive to buy, and not many pages are printed and the nozzle gets blocked if you don't use it much. People get refilled when they run out of ink, so the company installed an ink tank to refill the ink automatically.

If you desire to produce more full-color prints, opting for a printer equipped with a tank system is advisable. While printers utilizing cartridges can also print, they have limitations on print volume and require frequent cartridge replacements. In contrast, tank systems feature tubes connecting the ink tank to the cartridge, ensuring a continuous ink supply. During printing, the cartridge is heated to discharge ink, and the airtight tubes prevent ink from backflowing, thereby maintaining an automatic ink supply.

Initially, the tank system was installed externally on the printer for testing purposes to evaluate its functionality and identify any potential problems. Observations were made to understand the challenges faced. Eventually, some companies placed the ink tank on the right side of the printer, but this made it difficult to transport the printer to customers, so Canon invented the ink tank inside the printer.
