Lexmark MS81 Series - Supported Paper Sizes, Types, and Weights; Auto Density Sensing; Paper Types and Weights Supported by the Printer

Auto density sensing
The image density sensor assembly uses a reflection type sensor that detects a pre-placed toner patch and image on
the photoconductor (drum) and outputs pulses when the central line of the patch image aligns with the central line of
the detector. The sensor outputs pulses at the timing the patch image passes the sensor. Therefore observing changes
of intervals at which pulses are output leads to toner density detection.
