A laser printer is a type of printer that utilizes a laser beam to produce an image and graphics on a drum. It uses some basic technology like a photocopier. The modern printer has been come up with a myriad of color options, which offer HD pictures to be printed with precision and ease. From the School papers to corporate reports, you should need the printers.
What Is Laser Printers:
The various types of printers available in the market today. They use versatile technologies to achieve a similar end result of the printed page. The types are laser, inkjet, matrix, dot matrix, 3D, all-in-one, and more. Among this all, the Laser printer was the first to be invented. In 1969 the American Engineer sir Gary Starkweather was working on the xerox product development team. He thought that how to produce lasers to imprint an image onto a copier drum which would then be transferred onto paper. Hence, the name ‘Laser printer’. Laser printers are very cost-effective and efficient than other printers, so many people are choosing a laser printer.
How Does Laser Printer Work Step-by-Step:
- At first, you should push the print button on your computer, tablet or mobile devices to send the information in printer memory data stored.
- The printer is starting to warm up and you should wait. In this time the corona wire is heating up and get ready to pass its positive static charge to the drum.
- It has received a positive charge across the whole surfaces and the drum (coated metal cylinder) started to roll. Many printers have available 4 drums one for each Color-Cyan Magenta, Yellow and black.
- The laser beam is against a series of mirrors to reflect across the surfaces of the drum imprinting the shape of your print using an opposite negative electrical charge
- The drum slowly releases positively charged carbon toner particles on the drum and the transfer belt rolls the paper through the printer giving it a positive charge.
- The laser toner cartridge is then melted to the paper by the fuser unit and voila, now your page is printed.
Working of Laser Printer – Full Explanation:
How does laser printer work: While you go to do print something, you need to use a laptop, computer or smartphones to sends a large stream of data to your printer. The laser printer has an onboard electronic motherboard which receives the data from the laptop or computer devices. Now it decodes all the data sent into sample machine language, which is making the different components of the laser printer act in the right way.
When the data has been decoded, the electric motherboard goes on to activate the corona wire. It is a so high voltage wire which goes on to pass static chargers. The corona wire is complete the charge up the photoreceptor drum. The photoreceptor needs a positive charge on its surfaces. In that time the electric motherboard activates the lasers. The photoreceptor drum is positively charged by the laser.
A mirror is employed here which is bounce the laser onto the photoreceptor drum. Now it’s time for hits the photoreceptor drum and erases the positive charge which developed the photoreceptor drum. If it is failed to positively charge then the negative charge is entered here. The negative charge delivers a layout for the printable material.
It has available the ink roller, that was in contact with the drum. It is consists of tiny particles of powdered ink known as toner. The toner cartridge provides a positive charge, so it only attaches to the photoreceptor drum with a negative charge.
Printer Components Explanation:
A toner cartridge has been allowing color or carbon/iron oxide powder (toner) which is positively charged, then melted onto the paper. Toner Cartridges are a consumable item. It needs to be replaced when a laser printer cartridge is empty.
It is a very important thing to know about A drum unit. It is a metal cylinder that has a special coating (green color). it can receive a static positive and negative electrical charge from the laser within a laser printer. It is seen the printer as a green cylinder and sometimes built into the toner cartridge rather than a standalone unit.
The laser is one of the most important parts of the printer which transmits light from the diode across to a series of mirrors. It reflects the laser onto the drum unit to imprint the shape of the intended print.
The transfer belt is a very essential part of the printer. It moves the paper through your printer and passes it across the drum so that the toner can be transferred. Some of the smaller printers do have not a transfer belt but instead, have rollers that act in the same way as the belt.
It is a heated roller that melts the toner particles onto the page as it passes through. This seals the toner cartridge to the page so it’s no longer in powder form. It makes sure that the toner doesn’t smudge or fall off the paper when it comes out of the printer.
