Lexmark 40X9136 Fuser Maintenance Kit is a replacement service kit for supported Lexmark printers. Its 220–240 V fuser helps restore the printer’s paper heating and transfer components as part of routine maintenance.
The kit includes the fuser, redrive, transfer roll, pick rolls and other replacement parts. Lexmark recommends installation every 200,000 pages, using an average of 3 pages per job and approximately 5% print coverage as the basis for that interval.
The product page lists the MX511dhe and MX511de among compatible printers.
