I ripped apart an HP printer and on the back of the carraige that the
moved the print heads around was an encoder and a 400 LPI encoder
strip. The encoder is labeled H9721P. I can not find a datasheet for
it, but there are only 4 pins. I'm guessing one is power, another is
ground, then two sensor outputs. I'm curious if the is any way to
determine what pins are what?

It looks like C2 connects pin 2 to pin 4 (if you count the pins from
left to right as viewed on the "front" image)
TIA!
