For what it's worth, at the printing plant we blow paper waste (trim) into a cyclone and baler system, same principal as wood shop dust collection. It uses a very simple electric eye, looks like the safety sensor setup on your garage door, to cycle the baler when the hopper gets full. What makes it work is a timing mechanism that requires the break in the light beam to be 5 minutes before it cycles. So it undoubtedly gets blocked when we're blowing paper in, but even when the paper flow is from multiple machines the flow isn't continuous.
So I think you would need the timer to, especially when using something like a planer. I go for the translucent garbage can.
