Replacing laser printer toner cartridge *
Replacing your printer toner cartridge is usually fairly easy. These instructions are for a SAMSUNG printer but the process is the same for many printers. Toner cartridges that are used in laser printers are filled with black powder (toner). If you remove the cartridge and shake it for a few seconds before placing it back in the printer you may get some extra pages when the toner cartridge is flagged up for replacement .
