TONER SAVE MODE
You can turn on or off the toner save mode as follows:
Display Message Toner Save Mode
TONER SAVE=OFF Turn off the toner save mode.
(Factory setting)
TONER SAVE=ON Turn on the toner save mode. The amount
of toner on the paper decreases and the
printed image may look lighter.
POWER SAVE MODE
You can turn on or off the power save mode as follows:
Display Message Power Save Mode
POWER SAVE=ON Turn on the power save mode. The fixing
assembly of the print engine is turned off
after the specified time to save power.
(Factory setting)
POWER SAVE=OFF Turn off the power save mode. The fixing
assembly of the print engine is always
powered on to keep its temperature at the
specified level.
When you turn on the power save mode with the
Set button, the display
shows the next sub-setting menu.
You must set the time out for the power save mode from 1 to 99 minutes
with the ▲ or ▼ button: factory setting =30 minutes. The time out is the
duration after which the fixing assembly of the print engine is turned off
(“SLEEP”) to save power.
When the power save mode is on, the printer automatically turns on the
fixing assembly again after it receives data from the computer. Since the
fixing assembly must reach the specified high temperature, it takes a
slightly longer time to start printing the first page.
