I can print to my TR4520, but can't scan from it. When I try from the computer I get an error that it cannot communicate with scanner, and code 2,157,50. When I try to scan from the scanner, it says "please wait a while" and then goes back to the main menu.
I know the device is working because I literally printed something, signed it, and tried to scan it to send it back, and it won't scan. I'm following the instructions from the button in the scan utility, and have verified that my scanner is the one selected in the "scanner selection" window. All the cables are plugged in tightly. I don't know what else to try.
