|Maintenance Kits are a collection of replacement parts for your printer, to help keep the printer running like new. Each printer has a certain number of printouts it can handle before the components inside the printer start wearing down and losing their ability to function efficiently. As a preventative measure, the printer will display a message stating that maintenance is needed after a certain number of printouts are created. These kits will typically include a transfer roller, a fusing roller, separation rollers, and separation pads, seeing as to how these components work the hardest inside of the printer to create a printout. The electrostatic transfer roller is located underneath the toner cartridges and is responsible for picking up and releasing the toner to the paper, much like a magnet uses electrostatic charges to attract and repel certain objects. Once the toner is on the paper, it passes through a heated roller pressed up against the drum, known as the fusing roller. This will melt and compress the toner particles into the page. Changing these two parts will help keep sharp detail and crisp line accuracy on images and printouts. The separation rollers and pads are responsible for grabbing the paper from the tray and feeding it through the printer. When the separation components wear down, the printer will start having frequent paper jams. The elements that comprise each maintenance kit will vary with the different types of printers. Some kits will include fan accessories, corona assemblies, gloves for cleanliness, and other replacement parts depending on the printer and manufacturer.
