Other Control Features

The printer has the following useful features:

Sleep Mode

When the printer does not receive data for a certain period of time (timeout), it
enters sleep mode. Sleep mode acts as though the printer was turned off. The
default timeout is 5 minutes and it is automatically adjusted to the most suitable
time-out setting depending on the frequency of your printer use (Intelligent Sleep
Mode). While the printer is in sleep mode, all the LEDs 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
button 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 45 seconds. The Ready LED blinks to indicate that
the printer is warming up.
You can change the timeout for the sleep mode with the supplied printer driver
(all models) or Remote Printer Console program. Refer to the Help section in
the printer driver or RPC program for more information about the sleep mode
setting.
