How do I fix an E20 message on my SAM4s ER 5115?
Someone did an X report on the SAM4s ER 5115 cash register and left the machine in X report mode. Then a few minutes later, he pressed no sale to open the drawer, having forgotten first to return to reg mode. Now we get E20. We read in the manual that the machine requires a cash declaration, but don't know what to do next! It beeps no matter what key we press.
