The photoreflector-based media sensor detects the presence or absence of paper on the platen.
The sensor detects the presence of paper when it receives sensor light reflected upon the paper.

The feed roller HP sensor sets an LF eccentricity correction home position by detecting transitions from black (shielded) to white (transmitted), or a reference, in
the scale in the code wheel.
Feed roller encoder
