Sleep mode (hp lj 9040mfp/9050mfp/9500mfp)

To extend the life of MFP components and to meet Energy Star energy use guidelines, the MFP uses
a sleep mode to conserve energy use. To further extend the life of the control panel backlight, thebacklight will turn off after 15 minutes of MFP inactivity (the backlight also turns off when the MFP
enters sleep mode). Table 52 below, describes the energy use behavior of the MFP components
whenthe MFP is in sleep mode.
Sleep mode 1 is not configurable. The MFP enters sleep mode 1 after 15 minutes of inactivity. Sleep
mode 2 is configurable. The MFP enters sleep mode 2 after 45 minutes(default setting; this setting is
user configurable) of inactivity.
Note Sleep mode can be enabled or disabled by using the control panel menus (RESETS submenu) or by
pushing the SLEEP button on thecontrol panel. Pushing the SLEEP button while the MFP is in the READY
(waiting for a print job) state begins the sleep mode (sleep mode 2). Pushing the SLEEP button while
the MFP is in sleep mode,returns the MFP to the READY state.
Sleep mode 1 is defined as a level of MFP power consumption of less than that used when the MFP
is in the READY (waiting for a print job) state, and more than thatused when in sleep mode 2. Sleep
mode 1 begins when the MFP has been inactive for 15 minutes (the 15 minute delay time is not
configurable). Sleep mode 1 is the equivalent of the Energy Starprogram “Low Power” mode.
Sleep mode 2 is defined as the lowest level of MFP power consumption possible without the MFP
power being turned off. Sleep mode 2 begins after the MFP has been inactive for theamount of time
that is set in the SYSTEM SETUP menu SLEEP DELAY sub menu (45 minutes is the default setting).
Note When the SLEEP MODE setting in the RESETS submenu is set to OFF, and a SLEEP DELAYsetting is selected
in the SYSTEM SETUP menu, the SLEEP MODE setting in the RESETS submenu is automatically set to the
ON or OFF option (which ever was the last saved option).
