Sleep Time
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 30 minutes. When Intelligent
Sleep Mode is selected, it is automatically adjusted to the most suitable time-out setting depending on
the frequency of your printer use. While the printer is in sleep mode, the light on the display is 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 one of the buttons will also wake up the printer.
Sleep mode can be turned off. To turn sleep mode off, go to the Advanced tab, select Device Options
and then select Sleep Time. Double click the word Sleep Time in the Sleep Time screen, this will allow
the Sleep Time Off function to appear, click Sleep Time Off to stop the printer going into sleep mode.
The Sleep Time Off function can be hidden by double clicking the word Sleep Time in the Sleep Time
screen again. We recommend that you keep Sleep mode on for power saving.
