Brain Scan Came Back Negative

(I run a bit of a computer support business as my side hustle. My customer has just purchased a new multi-functional printer and is confused about how scanning works.)

Me: “This is how you scan. You can put the paper on the feeder here or on the glass here.”

Customer: “But will it scan double-sided on the glass?”

Me: “No, as the laser only faces the glass and it does not matter if you’re scanning because—”

Customer: “So, you are telling me if I put my face on the glass it won’t scan my entire face?”

Me: *facepalm* “I think what you need is a camera.”
