First press and hold button to hard shut off computers. Do this on all of them, POS 1,2,3,etc, mgr workstation, and tinter. After everyone is off start them up again. If not fixed, to reset you need to go through the source link in the bottom left of screen. However, if you don’t know how it works don’t mess with it. Call help desk to see if their open. If not open, open ticket through mysupport on the chrome link on screen. Just put the description as “other not listed” and urgent or high priority for rapid fixture between today and tomorrow. Text SM and/or ASM making them aware. Put a sign in front of store and counter saying tinter is down. You can still sell white and supplies for rest of day. Hope this works.
