Bio-scan doors

[Grungler Actual]

Is there some trick to getting my dupes to activate bio-scan doors? They only seem to interact with them after I've dug an alternate entrance to the room behind them, and usually not even then.

The only thing I know of is that there has to be a tile in front of the door for them to stand on while they put their hand on it.

Sometimes I have this issue now too... I deconstruct the door then order a dupe to walk into the dark area.

They are one-way.

For clarification, the "front" of the door is where the scanner is closest to the side of the door.

Some of the points of interest with bioscan doors can end up in a place where you won't usually be thinking about what direction to approach it from; if you breach a POI through a gap, but the door is still "unexcavated" on the side closest the scanner pad, your dupes can't pathfind to it, because the "front" isn't accessible
