Applies To

Details

The above printer firmware versions were enhanced to support a power saving mode that affects the Wireless Radio by powering off during periods of inactivity. The act of coming back online takes time that may affect the response. 

Taking the printer out of power save mode will keep the Wireless Radio Powered on. The default is "best" 

Procedure

A SetGetDo command is used to turn the power save off. 

To view the present setting use the getvar command

! U1 getvar "wlan.power_save" 

To turn the power save off use the setvar command

! U1 setvar "wlan.power_save" "off"

This setting is saved and will remain unless set back to "best" or if the printer is defaulted.
