The printer Real Time Clock has not been set to the correct time and date.

The Real Time Clock on the printer can be viewed by sending the command

Example: ! U1 getvar "rtc.date".   

The real time clocks date will be returned to the host.


If you observed the Real Time Clock is causing the certificate problem described, correct the clock time by sending the following SetGetDo command line
