Finally figured out why those Moseley T-cars keep kicking errors

Was on a call last week at a 12-story office building in downtown Dallas, the third time this month for the same MRL. Kept getting a door zone fault on the 7th floor but everything looked fine mechanically. Overheard the building engineer mention they repainted the lobby trim last month. Turns out the reflective tape on the hoistway door was swapped for a cheaper non-reflective version. Swapped it back with some 3M stuff and she's been running clean. Anybody else run into phantom faults from building maintenance crews messing with things?

Man, I gotta disagree on this one. Those T-car faults are usually a bad encoder or a loose belt, not paint.

Remember last month when @troyreed swore it was a bad controller board and I spent two days chasing ghosts, only to find it was a paint chip stuck to the sensor lens? lol. I've learned to never rule out the dumb stuff, it's always the thing you least expect.
