No laser printer can print without toner. However, few people know how to choose the right supplies for high-quality and trouble-free printing. From our article you will learn how to choose and use the right composition.
Toner is a specific powder ink for a laser printer, through which printing is provided . Electrographic powder is a material based on polymers and a number of specific additives. It is finely dispersed and light alloy, with a particle size in the range of 5 to 30 microns.
Powder ink differs in composition and color. They are different: black, red, blue and yellow. In addition, compatible white toner also appeared on sale.
During printing, colored powders are mixed together, forming the desired tones on the printed images. It is possible to dissolve the powder due to the high printing temperature.
Microscopic particles are perfectly electrified, due to which they reliably adhere to the charged zones on the surface of the drum. Toner is also used to create stencils, for which a special density amplifier is used. It allows the powder to dissolve and evaporates after use, increasing the contrast of the image.
There are several ways to classify toner for laser printers. For example, by the type of charge, ink is positively or negatively charged. According to the method of production, the powder is mechanical and chemical. Each variety has its own characteristics.
Mechanical toner is characterized by sharp edges of microparticles. It is made from polymers, components that regulate the charge. In addition, it consists of additives and modifiers, dyes and magnetite.
Such varieties are not in great demand today, unlike chemical toner, which is created through aggregation of emulsions.
The basis of the chemical toner is a paraffin core with a polymer shell. In addition, the composition includes components that control the charge, pigments and additives that prevent the adhesion of microparticles of the powder. This toner is less harmful to the environment. However, when refueling it must be extremely careful due to the volatility of the product.
In addition to two types, ceramic toner is also on sale . This is a special ink that is used together with the developer when printing on decal paper. With its help, ceramics, porcelain, earthenware, glass and other materials are decorated.
Toners of this kind differ in the resulting color palette and flux content.
- According to magnetic properties, the dye is magnetic and non-magnetic. The first type of product contains iron oxide, called a two-component toner, as it is both a carrier and a developer.
- By the type of use of the polymer, toners are polyester and styrene-acrylic. Variants of the first type are characterized by a lower softening temperature of the powder. They are perfectly fixed on paper at high printing speed.
- By the type of use, toners are produced for color and monochrome printers. Black powder is suitable for both types of printers. Color inks are used in color printers.
How to choose?
When buying supplies for a laser printer, you have to consider a number of nuances. Toner can be original, compatible (optimally versatile) and fake. The best type is the original product that is produced by the manufacturer of the particular printer. Most often, such powders are sold in cartridges, but buyers are frightened by their prohibitive price.
Compatibility is an important criterion for the selection of a consumable . If there is no money to buy the original powder, you can pick up an analog of a compatible type. Its markings indicate the names of the printer models for which it is suitable.
Its price is quite acceptable, the volume of packaging varies, which allows you to choose the best option for long-term use.
Fake goods are cheap, but they are harmful to humans and are often manufactured in violation of production technology. Such a consumable damages the printer. During printing, it may leave spots and streaks on the pages, as well as other defects.
When buying jars of any volume, you must pay attention to the expiration date. If it comes out, print quality will deteriorate, such a powder can shorten the life of the printing device.
How to refuel?
Toner refill depends on the type of printer. As a rule, consumables are filled in a special hopper. If it is a toner cartridge, open the printer cover, take out the used cartridge, put a new one in its place, filled up to a distinctive click. After that, the lid is closed, the printer is turned on and printing is started.
When it is planned to refill a used cartridge, put on a mask, gloves, and take out a cartridge . Open the compartment with waste material, clean it to avoid printing defects during further printing.
After that, open the toner hopper, pour out residues and replace it with a new dye.
At the same time, it is impossible to clog the compartment to the eyeballs: this will not affect the number of printed pages, but the quality can noticeably decrease. Each printing device is equipped with a chip. As soon as the printer counts the specified number of pages, printing stops. It is useless to shake the cartridge - the restriction can be removed only by resetting the counter.
If the cartridge is full, defects may appear on the pages. To eliminate the malfunction, it is reinstalled in the desired position. Do this after filling the cartridge with prepared toner. After it is shaken slightly in a horizontal position so that the toner is distributed inside the hopper. Then the cartridge is inserted into the printer, which is connected to the network.
As soon as the counter works, a new countdown of the printed pages will begin. For safety reasons, you must open the window when refueling. To prevent toner from remaining on the floor or other surfaces, it is advisable to cover the working area with film or old newspapers before refilling it.
After refueling, they are disposed of. Discarded waste material from the sump.
