sounds like the lamp/led is off
Thanks!. I asusme the otuputs are high if the corresponding sensors are
dark, then.
This encoder is supplied in 3 piexes according to the manual. There's a
housing that scred to the ebaring cover plate in the printer. A slotted
encoder disk that's then glued to the leadscrew. And an end cover that
clips onto the end of the casing, this carries the light source (I assume
IR LEDs).
When I next work on the printer, I'll invesigate the powering and
operation of those LEDs.
