Sometimes your printer won’t print in black and white if a color is out because it uses all of the colors to create a deeper black. Depends on the model though.
And some of them use yellow as a lubricant because yellow toner has a consistency close to water.
Also, please do not copy money or your butt. Trust me.
Also used for printer tracking dots.
I remember hearing that money is n issue since it has some copy protection features, but your butt? What’s wrong with that? (Other than sitting on a piece of electronic equipment, lol.)
I have had a “biohazard” call at a local college.
The platen glass is a lot thinner than it looks!
Also, depending on the model of the copier, it will not let you copy money, and if you attempt it too many times, it will literally brick the machine.
Something cool to do is to take your phone and turn on the selfie camera. Lay that on the platen and make a copy to see a trippy pattern.
If you want to screw with someone, lay a single paperclip on the platen and make a bunch of copies of it. Take your copies and shuffle them into the paper tray face up (assuming you’re using an office laser copier) so every once in a while, someone will get a paper clip on their print.
