Customer ejects 13 tapes into extended mailslot.

The robot fills the mailslots - no problem.

Open CAP from Op Panel - Small CAP pops open - Large CAP is released to pull out.

Customer gets all tapes out of the CAPS - pushes both CAPs back in at the same time.

Cause

Defective CAP Sensor. The thin metal flange not seating tight to the plastic sensor-flag tab.

Solution

Found out that the CAP sensor (for the 4-slot CAP) is indeed on the Robot. With that information the plan was to pull the Robot and check for any loose connection to that sensor. There was no evident problem so the Robot was replaced. Pulled the 4-slot CAP out to inspect it and found the thin metal flange not seating tight to the plastic sensor-flag tab. No idea if this had anything to do with the intermittent problem of not seeing the CAP open but it was corrected anyway.

This is a picture of the CAP sensor that is on the Robot - circled in red.

This is a general picture of the CAP sensor-flag for perspective.

CAP Sensor Flag

The "GAP" picture below shows the thin metal flange not fitting tightly to the plastic sensor-flag tab.

Sensor Gap

The "Fixed" picture below is after I unscrewed the metal plate (T20) and bent it together to fit tightly to the plastic tab and screwed it back on.
