CLEAR
MAINTENANCE
MESSAGE
There is no value to
select. Appears after the PERFORM PRINTER
MAINTENANCE message. The PERFORM
PRINTER MAINTENANCE message can be
temporarily cleared for approximately 10,000
pages, and then the message appears again.
When the PERFORM PRINTER
MAINTENANCE message first appears, a new
maintenance kit should be installed to maintain
optimum print quality and feed performance.
For more information, see Performing preventive
maintenance . To order the printer maintenance
kit, see Part numbers .
SLEEP MODE *ON
OFF
Turns Sleep Mode on or off. Using Sleep mode
offers the following advantages:
● Minimizes the amount of power that the
printer consumes when it is idle
● Reduces wear on electronic components in
the printer (turns off the display backlight,
but the display is still readable)
The printer automatically comes out of Sleep
mode when you send a print job, press a printer
control panel button, open a tray, or open the top
cover.
You can set how long the printer remains idle
before it enters sleep mode. See the SLEEP
DELAY information in the
System Setup submenu .
