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.

Output expander theory
The output expander enables the user to have additional output capacity. If the standard output bin of a printer is
already full while printing, the media can be sent to the output expander. The output expander uses drive motors and
a series of sensors to determine the media's location and position in the paper path.
