Lexmark MS510 MS610 MX310 MX410 Media Flag 40X8800
Replacement Printer Component
Lexmark Media Present Sensor Flag
Replacement media-detection flag for select Lexmark MS, MX, and XM monochrome laser printers.
Restore Reliable Media Detection
The Lexmark 40X8800 media-present sensor flag is a replacement component used within the printer’s paper-handling and media-detection system. As paper moves through the printer, the flag interacts with the sensing mechanism to help the device recognize the presence and movement of media.
A damaged, worn, broken, or sticking flag may contribute to false paper-jam messages, media-detection errors, unreliable paper pickup, or interruptions during printing. Replacing the affected component can help restore proper sensing when the media flag has been correctly diagnosed as the source of the problem.
