What: Authenticating at the printer for first time after waking the printer from long sleep mode takes longer than expected. This is seen when user authentication is attempting connection to Active Directory (AD) that has entered into idle state.
The following symptoms might be seen:
Why: When AD is in idle state and user tries to connect to AD (via Web Admin or by authenticating against AD at the printer), it takes around 20-25 seconds for connection to get established for the first time. Consecutive connections and authentications tend to be faster once the AD is up and running.
What's next: This is an expected situation, once the initial connection with AD is successfully established, successive authentications at the printer tend to be faster.
