Like everything else, printers are susceptible to wear and tear. Over time, fuser assemblies, transfer units, and various other rollers and pads will likely need to be replaced. Printer maintenance kits typically include a fuser assembly, transfer roller assembly and additional feed and charge rollers. At Office-Link, we offer high quality compatible Lexmark maintenance kits at a fraction of the price you would pay for OEM equivalents. All of our compatible printer maintenance kits come with step by step instructions.
