Many people use machines without plastic welder knowing the mechanisms and technology

properly. It is true that for using a machine effectively, you just

need to know how to operate it.

Many of us tend to buy

and use machines without knowing the mechanisms and technology

properly. It is true that for using a machine effectively, you just

need to know how to operate it. But, if there is a sudden breakdown

of the machine, you have to call for professional help. Lack

knowledge about the working mechanisms do not let us understand minor

faults in the machines, which are not easily solvable.

Printers are such machines that are used by almost everyone these days for

printing documents and taking copies of written work. Among the

different types of printers, the machine that is commonly used is the

laser printer. Let us discuss in brief about the working of the laser

printer and the maintenance of the laser

cartridges.

Laser cartridges use

excellent quality toner for producing marvelous printouts. The

mechanism of printers using such cartridges also allows it to print

a large number of pages within a short time.

Laser printing is

also called “Electrostatic printing” and is vastly different

from the way in which an inkjet or dot matrix printer operates.

Laser cartridges use electrical charges to produce the images on the

printouts.

In the process of

printing by using laser cartridges, light photons are discharged

into the transparent cylinder inside the printer. When a laser beam

is fired into the cylindrical drum, letters and images are received

by the drum in the form of electrical charges. This drum is coated

with toner which acts as an anode (positively charged end). The

printing job is done by rolling the negatively charged papers

(cathode) into the cylinder.

Inside the laser

cartridges there are four toners – cyan, magenta, yellow and

black. Remember, if any one color runs out, the printer can still

print documents by using the other three colors. So, there no need

to change the toner until the last cartridge is used up.

You need to know these

basic mechanisms so that you can at least know the root of the

problem in case of a complete breakdown. But there can be some minor

faults that you should be able to tackle. For example in case of a

paper jam, you must check if it is the result of an improper paper

feed. If the laser cartridge is not giving good quality printouts,

you must remove, shake, and replace it in the machine.
