Lexmark ADF Maintenance Kit 41X1592 is a service part for the automatic document feeder in compatible Lexmark multifunction printers. It brings together the feeder components specified for maintenance: media pick rollers, a separation roller and a feed belt.
Lexmark recommends installing the kit at 200,000 scanned pages. This gives a clear service interval for planning maintenance of the document feeder.
The manufacturer lists compatibility with CX921de, CX922de, CX923dxe, CX923dte, CX924dxe and CX924dte. The kit is intended for the ADF, rather than general printer maintenance.
