Toner

You can find cheap toners here at Eurotone.de

Toner is one of the most important consumables in a laser printer. Anyone who uses a laser printer should stock up on enough replacement cartridges to avoid unnecessary print failures. It is always annoying when important documents cannot be printed out because the printer asks for new toner and there is no suitable toner cartridge at hand.

It is difficult to stock up on new cartridges on weekends. We would therefore like to recommend that you order fresh toner cartridges in good time and recommend them in this way. You can buy these cheaply here at Eurotone, along with other printer accessories.

What exactly is a toner?

The toner is a special printing medium for the electrostatic printing process. It is required for all laser printers and copiers. It consists of a very fine powder with a very small particle size.

It is interesting that the dry toner powder is very liquid and therefore behaves like a liquid. It consists of various pigments, synthetic resins, binders and magnetic metal oxides.

High demands are placed on production. It is known that laser printers achieve very high quality printing results with their toner cartridges.

The toner must therefore not absorb moisture during the printing process, must remain color-fast and should only have very little plastic applied to the carrier material.

One of the greatest advantages is that the color toner remains absolutely smudge-proof after it has been melted. Even external moisture can usually not affect the printout. So it is not surprising that laser printouts are used outdoors, among other things.

What types of toner are there?

The one-component toner

In addition to the fine pigment powder, a one-component toner also consists of magnetic additives. These particles immediately come close to the magnetic core of the developer roller when the particles straighten up. The rotating roller creates friction, which leads to a negative charge on the particles.

The erected pigments of the toner then adhere to the rotating photoconductor drum.

In the case of one-component toners, it is usually only the printing color black. The developer already contained in the toner would falsify color pigments.

The two-component toner

Color laser printers use two-component toners. Developer and color are separate so that color falsifications are impossible. This special toner is also required for color copiers. The developer consists of fine iron particles. While the iron particles were manually filled into the developer unit in the first color laser printers, these are already contained in the developer unit today. This way, only the ink needs to be added through the ink cartridge.

With modern laser printers, not only the toner cartridge but also the developer unit is replaced. The right mixing ratio is important. Too high a proportion of iron particles in the developer can damage the photoconductor drum. The new printer takes over this measurement of the mixing ratio automatically.

The transmission fluid

The so-called transfer liquid is an interesting alternative. These are color pigments in dispersed form that are kept particularly small.

The exposed image drum of a laser printer rotates in this transfer liquid and absorbs the pigment color.

Since this printing process does not require subsequent fixing and the particle size is much smaller than with the other toner particles, this laser printer can achieve a significantly higher print quality.

How does the toner actually get onto the paper?

The laser printing principle is also known as the Xerox process. The first laser copiers were developed by the American company Haloid Xerox in the 1950s. Electrophotography was henceforth called xerography. In 1961 the company was renamed Xerox. The imaging drum coated with a photoconductor is one of the most important components of a laser printer or copier.

Loading the imaging drum different colored toners

The photoconductor is the coating of the image drum. This has to be electrostatically charged by means of a thin wire, also known as a charging corona. A corona discharge is generated by a high voltage. Recently, a charging roller has also been used instead of a wire, since practically no new ozone is generated during this process.

The exposure of the imaging drum

Even before it is printed out, the electronics of a laser printer know what the subsequent print image should look like. The charge of the photoconductor on the image drum is therefore extinguished wherever the fine toner powder is supposed to adhere later. The discharge takes place through a kind of exposure. The more light falls on the photoconductor of the imaging drum, the more it is discharged. Older laser printers actually use a fine laser beam for exposure. Today's laser printers generate this exposure with the help of light-emitting diodes.

The subsequent print image is projected onto the photoconductor or the image drum via a rotating mirror. Grayscale can therefore also be created with halftone screens. In professional laser printers, color gradations are made by gradually reducing the charge over 256 levels. One speaks here of 265 gray levels.

Develop with the developer unit

The image drum with the photoconductor coating is now exposed with the print image. One rotation brings the photoconductor close to the developer unit. The static charge pulls the fine toner powder onto the photoconductor. This also explains why the toner powder contains minimal magnetic particles. The developer unit also takes control of the contrast range and prevents too much toner from sticking in one place. Synthetic resin in the toner provides electrical insulation.

The transfer of toner onto the paper

Depending on the version of the laser printer, the photoconductor brings the adhering toner directly into contact with the paper. There are also models in which the toner is first transferred to a transfer roller or ribbon and only then onto the paper. Modern color laser printers have four successive printing units for the colors black, cyan, magenta and yellow. This allows color prints to be made in one go.

When using a transfer ribbon, the toner is applied to the paper by means of an electrostatic charge. This means that the fine toner particles are now on the paper to be printed.

The fixation of the toner on the paper

Subsequent fixation is necessary so that the toner powder remains permanently and smudge-proof on the paper. Therefore, the paper is moved to the fixing unit. This usually consists of two rollers coated with Teflon or silicone rubber. One of the rollers can be heated to a temperature of around 180 degrees Celsius. In this way, the fine toner particles melt and perpetuate themselves permanently with the paper. So that the toner does not stick to the rubberized rollers, the upper roller is provided with a slightly repellent electrostatic charge and the lower roller for the back of the paper is provided with a slightly attractive electrostatic charge.

Newer devices only get by with a heating roller, while the underside consists of a non-stick adhesive tape. It should be noted that the fusing unit wears out over time and can then no longer achieve the required heating power. They then have to be replaced. The fixation of the toner on the paper can be recognized by the fact that it feels quite warm after the printed side has been ejected.

Closed works

After the smudge-proof print side has been output, all components are completely emptied. The waste toner on the components is diverted to a special waste toner container. This can later be fed back into the recycling cycle.

How to properly handle toners

Toners consist of various components that ensure an excellent print image, but as fine dust they are not harmless to humans. Under no circumstances should you handle loose toner powder, especially since this can also lead to heavy soiling. Therefore, toner cartridges consist of a closed container made of sturdy plastic.

Depending on the manufacturer, the housing can have different shapes and sizes. The elongated shape of the bar has proven particularly useful. Lateral plastic guide lugs ensure that the toner cartridge can be inserted correctly into the laser printer's toner slot. With color laser printers, a separate toner cartridge is required for each printing color. These are usually inserted into the toner cartridge one after the other. With other laser printers, the individual cartridges must be pushed into the openings on the side.

These cartridges are usually offered in cardboard packaging on which all of the manufacturer's body information can be recorded. In the case of color cartridges, you will also find the right printing ink here at a glance. Each cartridge is sealed again in a light-tight foil packaging. Before you can insert a toner cartridge into your laser printer, remove it completely from the packaging.

Inside the toner cartridge, the fine toner powder is usually not evenly distributed in the housing due to the transport. This can lead to difficulties during commissioning and, in the worst case, to an unclean print image. Therefore, most manufacturers recommend shaking a fresh toner cartridge horizontally and vertically a few times. As a result, the particles are optimally distributed inside and can easily reach the photoconductor of the image drum from the toner outlet if necessary.

The toner outlet is protected by a seal against unwanted leakage of toner powder on the transport route. Understandably, this seal must be removed before insertion. There are several possibilities for this. Sometimes when you peel off an adhesive strip or pull a plastic strip off the side of the cartridge housing.

This safe can be inserted into the cartridge slot by slightly angling the new toner cartridge. Then carefully press the cartridge housing down so that it engages in the holder. You can then close the toner container cover and start printing.

They are also free of shipping costs. However, this is based on a delivery within Germany. You can also have our toner cartridges and printer accessories delivered to many other countries.

What to do with empty toner cartridges

A used toner cartridge must never be disposed of in the black residual waste bin. The production of this plastic housing is relatively complex and expensive. If you have ordered fresh toner from Eurotone.de, you can use the outer packaging very well to store used toner cartridges. In this way, an empty cartridge can be safely returned to the recycling cycle.

You can also simply send us your empty toner cartridges back and we will take care of proper disposal. From 4 empty cartridges, there is also a free return stamp.

Since the plastic housing is usually in good condition, empty cartridges can be refilled with new toner powder (refill toner) with little effort. These will later be offered under the name Refill or Rebuilt Toner.

These are the points to look out for when purchasing toner

If you need a new toner cartridge for your laser printer, it must of course be compatible with the printer. Similar to printer cartridges or ink cartridges for an inkjet printer, it depends on the model. The exact designations of the suitable toner cartridges and other replaceable components can be found in the operating instructions for the respective laser printer.

If you order replacement toner cartridges here from Eurotone, you can not only find out about the respective cartridge models using the clear search function for your printer, but also find out which model is right for you using the article number and EAN number. This ensures that the selected toner cartridge really fits your laser printer.

Please note that there are toner cartridges of different sizes for many laser printers here in the shop. A distinction is often made between the standard and the XL version. Although the dimensions of these plastic housings are the same, the XL cartridges contain significantly more toner powder, so that a longer print range is ultimately achieved. You can print up to 1.500 pages with the standard cartridge, while YOU can print up to 2.500 pages with the XL cartridge.

If you order fresh toner cartridges from us, you will find that the larger cartridges cost only a little more and are therefore worthwhile in terms of a higher print volume.

Compatible toner cartridges bring you this benefit

If you buy toner cartridges particularly cheaply and still do not want to forego high print quality, then we recommend our compatible toner cartridges.

When comparing prices, you will find that you can buy these cartridges from us for significantly less than the originals. These cartridges perfectly match your laser printer and produce a brilliant print image.

Our own brand ensures minimal printing costs. Of course, using it does not invalidate the manufacturer's warranty for your printer. We guarantee you high quality on our compatible products.

Compatible toner cartridges are also recommended from an ecological point of view. Instead of complex packaging, these cartridges place great value on a high proportion of fresh toner powder.

This is not only good for the environment, it is also easy on your wallet.
