Switch; Other Control Features; Sleep Mode - Brother HL-720 User Manual

Switch

If you press the switch during printing, the printer immediately stops
printing and ejects the paper. It is recommended that you wait until the page
has finished printing, then press the switch, otherwise you will lose data on
the page.
If the printer is in sleep mode, pressing the switch wakes it up into the
ready state.
If the Data lamp is on, press the switch. The printer prints any data
remaining in the printer memory: this operation is called "Form Feed."
If an error occurs, the printer will recover from some errors automatically.
If the error does not clear automatically, press the switch to clear the error
and continue printer operation.

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 (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 20 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 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.
