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.
