The average laser printer can print up to 400 pages per minute.
Laser printers are a rare combination of economy, precision, and speed. They can print items in a very short time while using minimal ink. Besides, the printed copy is very high-quality.
So, how does a laser printer work? Here is a laser printer guide.
General Working Principle
The laser printer works by heating a wire that changes its charge on the area that it heats. The heated area becomes negatively charged and is representative of the text or image that you intend to print.
The printer then passes a toner roller over the drum. While this is happening, the negatively charged areas will attract toner particles. You will then put a sheet of paper under the drum as the toner passes on it.
This creates a copy of the image or document. For example, it can be a copy of custom Zine printing.
Step by Step Working Principle
A laser printer uses multiple steps to print a document. The order and mechanism of each step vary from one laser printer model to another.
The first step involves converting the document into a digital format and transferring it from the computer to a printer. The printer will then convert the data into a readable format.
Before the printer can process the current document, it has to remove the previous one. The process involves cleaning traces of the previous job. It also prepares the drum for the new job.
The printer has a rubber blade that removes the remains of toner particles. An electrostatic erase also eliminates the previous job’s electrical charges.
The printer’s wire begins to heat up. The wire also gets into a position where it can transfer electric charges to the drum.
The laser printer’s drum starts to rotate and accept electric charges on its surface. Some printers have multiple drums dedicated to a specific color.
As the drum rotates, the laser will shine a beam on it. The beam will be a representation of the document or image.
Toner particles with a positive charge attach to the rotating drum. They will then combine the negative laser beam on the drum due to static electricity. Areas of the drum with a positive charge do not attract the laser beam.
A media or a paper slide will move across the printer and become positively charged. The paper will then attract toner particles with a negative charge. The result is that the print outline will appear on the paper.
Cleaning and Recharging
The printer cleans and recharges the drum while it is still rotating. This happens through the release of electrically neutral materials onto the drum. Excess toner particles and positive or negative charges on the drum are cleaned out.
