A maintenance kit is a set of replacement parts for a printer. Each printer has a preset maintenance interval, which occurs after a certain amount of pages are printed. The maintenance interval lets the user know that it’s time to install the maintenance kit so that the parts within the printer do not get overused.PAPER PICKUP ROLLER KIT

Every printer and manufacturer is different, so the parts included in the kit will also be different. Parts that may be included in a maintenance kit are the fuser assembly, transfer roller, pickup rollers, separation pads, corona assembly, fan assembly, cleaning cloths and gloves.
The fuser assembly is a pair of rollers that fuse the toner into the fibers of the paper. A transfer roller is an electrically-charged roller located underneath the toner cartridge. When the paper passes through the drum, it also passes through the roller which transfers toner onto the page. Pickup rollers, often called feed or separation rollers, are used to pickup the paper from the tray and feed it to the printer. Separation pads are made to assist the pickup rollers by applying tension so that the paper is pushed to the printer. When the separation pad is worn down, it cannot push the paper properly which causes paper jams.

The following parts are not as common in maintenance kits as the parts listed above, and again depend on the printer and manufacturer. A corona assembly in the printer is the part of the printer responsible for the electrical charges. The drum, toner and paper must all be charged in specific ways so that the drum can place the toner onto the paper correctly. The fan assembly within the printer gives off just enough air to keep the paper flat as it enters the printer. Finally, cleaning cloths and gloves are often included within the maintenance kit to ensure proper care of the inside parts.

It is important to pay attention to the maintenance interval in your printer. Ignoring the alerts can potentially cause serious wear to your printer. Maintaining the parts inside your printer avoids permanent damage and the need for replacement.
