Ricoh SP C440dn Color printers shutting themselves off?

I haven't sold any of these yet, sorry

Yes.  I sold one an hour and a half away from my office and it took me two wasted visits to reproduce the issue when the customer complained.  There is a setting called "Eco Night Sensor" or something to that effect.  Turn it off.

The setting is in the web interface under the timer settings.  It is a setting that is easy to overlook and is now found on a couple other printers as well.

Thanks for the help. Can't help but wonder though why it has only effected the two most recent installations and not any of the dozen or so prior. This is a Windows 10 environment. Do you think that might be a contributing factor?

Possibly something due to two way communication.  The setting I am referring to is a setting on the printer though.  On the machine there is a sensor that can tell when you turn the lights off in the room.  You turn the lights off and the machine turns itself off after so many minutes.

My problem was corrected by deactivating the Eco Night Sensor. I guess other installations are just fine with turning the printer on every morning so they haven't complained. By the way, several calls to Ricoh Tech Support had us downloading Firmware, changing sleep modes and who knows what all else but one inquiry to P4PHotel got me the answer I needed immediately.

Thanks Fisher for being there AND taking the time to respond.

No problem.  As you've now figured out Tech Support can be pretty useless.  Took me two visits to figure it out for a customer an hour and a half drive away.  This feature is on several printer models and it is enabled from the factory.  Beware.

Be aware that this feature should be turned off on the SP4520DN machines too.
