There Are Numerous Causes For Picking Laser Toner Cartridges Cleverly

By Carolyn Pickett


Everyone needs something printed, and the choices are quite confusing about which type of printer to opt for. This is true for both the user at home, and in the workplace. The options are the inkjet versus another sort of printers, which use Laser Toner Cartridges.

As with most things there are a number of factors to bear in mind when making your choice, but your primary thought should be, about the tasks that you will mainly be using a printer for. If the content is largely picture based, then maybe an inkjet printer would be the best option. Whereas, for high quality textual printing, such a printer would fit the bill. The differences between the two basically boil down to, how they print, and the medium that they each use.

With an inkjet printer, the cartridges actually contain ink in a liquid form. When printing, miniscule droplets of ink are sprayed at the paper. This is done in an exact way, to achieve the printed image that you have selected. Since any colour within the broad spectrum can be reproduced, an inkjet printer produces excellent graphical results.

These printers however utilise something called a toner cartridge. Held within the cartridge is a very fine powder. This powder is made up from plastic coated particles of carbon, which have been treated with pigments to produce the colour. No actual inks, or liquids, are used. The printer itself utilises some basic electrical principles in operation.

In rudimentary terms, this kind of printer operates by using the principles of static electricity. In basic terms static electricity is, an electrical charge that has been built up on an item will attract particles that have an opposite charge. Using this basic principle, people have utilised it in the laser printer. At the centre of the printer you will find a rotating drum, made from highly conductive material.

When a printing task has been started this rotating drum has a positive charge applied to it, the laser beam will discharge certain areas causing an electrostatic images to be formed on the drum. Positively charged toner particles are then applied to the drum. Paper is passed under the rotating drum, as it has a greater charge than the drum; it effectively pulls the image from the drum onto the paper itself.

From there the paper gets passed between a pair of Teflon coated heated rollers. This causes the plastic coated toner particles to melt and bind to the paper fibres. As these rollers are Teflon coated the particles will not stick to them. To prevent the paper from scorching the operating speed has been carefully adjusted, although the paper will still feel warm to the touch.

As you can see there is a bit more of a complicated process involved with a laser printer. The cartridges also have a bit more to them than an inkjet cartridge. Having said that, Laser Toner Cartridges, with their lack of liquid, are not prone to smudging or blurring, and produce consistently excellent results.
