Other Control Features
Sleep Mode
When the printer does not receive data for a certain period of time (time-out), it enters
sleep mode. Sleep mode acts as though the printer was turned off. The default time-out
is 5 minutes. While the printer is in sleep mode, all the
lamps are off and it is as if it
was turned off, but the printer can still receive data from the computer. Receiving a print
file or document automatically wakes up the printer to start printing. Pressing the switch
also wakes up the printer.
✒ Note
When the printer goes into sleep mode, the fan will not stop until the printer engine
has cooled down.
Sleep mode allows the print engine to cool, so the temperature of your room and how
long the printer has been in sleep mode affects the warm-up time. This warm-up time
can take up to 30 seconds. The
Ready lamp blinks to indicate that the printer is
warming up.
You can change the time out for the sleep mode with the supplied printer driver (all
models) or Remote Printer Console program (HL-1040/1050 only). Refer to the Help
section in the printer driver or RPC program for more information about the sleep
mode setting.
