> Based purely on what a photocopier does, and without knowing anything about how it works, can you deduce the result of photocopying a mirror? Setting aside technology the only thing I'm left (no pun intended) with is the experience of a mirror's handedness swapping. It doesn't seem like the correct why (dark page) can be adduced from the fundamental of a light emitter/detector pair coupled with lateral motion across the thing being copied because the result would be undefined absent some averaging feature at the output, and that's not what happens with most photocopiers that generate a dark print, and those are all forbidden hows. Will you be posting additional hints here or at the OP? EDIT > Try to answer the question without referring to how the photocopier/scanner works, and only refer to what it does. The thing reproduces an image of the source, that is, the mirror. I'm not satisfied with that because it feels like it's begging the question or leads to a series of infinite reflections.
