2.9 Deep Sleep Function
In addition to the sleep function with the normal specifications, the deep sleep function is
prepared to reduce the power consumption.
The deep sleep function is used to stop the operation of the following functions whereas they
are available in the normal sleep mode.
- Operation of the wireless LAN
- Power supply to the paper tray 2
- Operation of all the fans
- Detection of files in a USB memory
<Transition conditions>
The printer goes into the deep sleep function when the user does not operate the printer (from
a PC) and no warning such as an error is issued after it goes into the normal sleep mode and
all the fans are stopped. When secure print exists, the printer does not go into the deep sleep
mode.
<How to Exit>
The printer exits from the deep sleep function when it receives an input from the outside, for
instance when it receives print data from a PC, or when any button on the control panel is
operated, or when the front cover is opened or closed.
