A toner cartridge, more commonly known as laser toner, is an extremely important part of a typical laser printer. Toner cartridges contain pigment-based ink, a finely dried mixture of chemical compounds, tiny plastic particles, and sometimes even tiny black or other colored coloring agents which create the actual image onto the paper. These images are transferred through the toner onto paper which has been heated to a specific temperature so that the ink will fuse into the desired areas. The thickness of the coating gives the printer the ability to precisely reproduce large areas of text or photos and to create very smooth finishes on photo paper. Without toner, printouts would be prohibitively thick, making printing much more difficult and time consuming. To purchase a quality lexmark t630 printer, check out this post.
Laser toner is used in both laser and inkjet printers. Because laser printers require toner for full functionality, toner cartridges for these printers must be very well made and manufactured in order to ensure that laser printers are able to deliver high quality work. Laser jet printers, by contrast, can use generic ink that may not be as effective as the specialized pigment-based inks that are produced by laser printers. It is possible to find generic toner for both laser printers and inkjet printers; however, they may not necessarily be as high quality as the inks designed specifically for laser printers. In addition, generic toner may not have the same high-quality ink formulations as brand-name counterparts.
Most HP laser printers require you to replace the toner cartridge whenever it becomes completely worn out. Even though HP laser printers generally last for several years before needing to be replaced, if they are not regularly maintained, they can begin to show signs of wear such as tiny tears on the rubber sealing around the imaging drum. These tears will become increasingly visible as time passes, but you should be able to identify signs of wear by looking at the size of the images that you are printing out. If the images are becoming too small or if they are being printed out in poor quality, it is recommended that you replace the toner cartridge as soon as possible.
The toner cartridge usually contains several components, including an imaging drum unit, a thin iron oxide layer, an ionic liquid flux, and a thin ceramic coating. The imaging drum unit is what actually does all the work when it comes to printing out an image. This unit consists of a plastic drum that holds the ionic fluid within it and is located directly under the toner cartridge. It functions by creating a magnetic field that attracts the iron ions. The iron ions then attach themselves to the image that is being printed out and allow it to be engraved into the drum's interior.

After the toner cartridge is replaced, you will need to install the imaging drum onto the printer's drum board. The Imaging drum can either be a Brother laser printer drum or an Epson printer drum. If you are using a Brother laser printer, the drum should be purchased from their web site. If you are using an Epson printer, you will need to find the appropriate model number for your machine.
When installing the drum, there are usually two methods available. You can either use the locking mechanism that is found on many older printers, or you can install a screw drive screw joint. Either method should be followed for proper installation. Once the imaging drum has been installed, reattach the clamshell and insert the toner cartridge. Reassemble the drum and you are all set, including the laser printer drum unit.
