SNMP-Polling fehlgeschlagen: Drucker nicht bereit. (E311)
I have registered an info email account, the user name is musterma, and the initial password has been changed. The printer can log in and print by entering the user name and password, but swiping the card does not work. The screen displays "SNMP-Polling fehlgeschlagen: Drucker nicht bereit. (E311) "
