Paper Jam: A paper jam describes when paper or other printed material gets stuck or lodged into a printer and cannot eject. When this occurs, the printer will not function properly until the document has been manually removed.
Replace Fusing Unit: A fuser unit is a pair of heated rollers within the printer that fuses the toner onto the printed paper.
Replace Drum Unit: A printer is essential to any arsenal of office equipment, and like with any office equipment, a printer needs regular maintenance. This includes switching out ink and toner and sometimes replacing printer drums.
Maintenance kits: Also called preventative maintenance kits. Nothing lasts forever. Many moving parts in printers need to be replaced over time and used. Usually, when the printer displays a message saying, "Performance Printer Maintenance," that means an installation of a maintenance kit is recommended. Installing the maintenance kit will ensure the optimum performance of your printer.
