CLEAR BOARD SENSOR message- I know you'll say "get a new one" but not an option

I wouldnt get rid of the clear cover.
Dust would build up fast, and the blowing/brushing/sweeping it clear all the time is gonna break something eventually- plus the lightpipe would get clogged.

Also, the Manual says "It is recommended that this sensor and mirror be cleaned after every project". Mirror? What mirror? Have I been missing something, a portion of the sensor, all along? Note that this is original RevA parts as I rec'd them from Sears.

Still no answer on the Mirror question?
Anyway, now I'm not getting ANY readings during sensor check besides "0". I pulled off the Y truck to check for shorting pinched wires, and they were fine- no crimps etc and continuity checks OK on each lead from sensor board thru to other end of wires.
I'm running out of ideas besides replacing things I can't afford right now. Any other tests to try?

There is no mirror that I'm aware of. I have had to replace the board sensor a couple of times. The last one I ended up taking the lens off and just blow it out after each carve.

I will eventually replace it.

I know people have been told to use a dental mirror to see the sensor.

The mirror was mentioned in the manual, as if a part of the sensor.

The lamps are both working, I can see them via my phone cam, but the sensor check says "0" during hand-pass test, cranked down head, with and without white masking paper overlay, etc.
I am considering a manual bypass with a PB-NC switch to 'tell' the machine where the board width and end points are- press the button/open the circuit to simulate the sensor reading the edge/end points. Exact dimensions aren't nearly as critical to me as getting running again- I can always trim around the piece to compensate. If I understand correctly, the Board Sensor is only in use during the measurement phase of set-up and not while carving, so manipulation of the switch will be brief.
Anybody have any experience along these lines?
Anybody have any schematics?
