Printer control panel problems
Control panel settings work incorrectly
Cause Solution
The printer control panel display is blank or is
not lit, even when the fan is running. Fans may run while the printer is in standby
mode (off). Press the printer’s on/off button to
turn the printer on.
Printer settings in the printing software
application or printer driver differ from the printer
control panel settings. Confirm that the settings in the application and
printer driver are appropriate, since the
application settings override the printer driver
and control panel settings, and the printer driver
settings override the control panel settings. For
more information about how to access the printer
drivers, see
Accessing the printer drivers .
Control panel settings were not correctly saved
after they were changed. Reselect the control panel settings and then
press . An asterisk (*) should appear to the
right of the setting.
The Data indicator light is lit, and there are no
pages printing. Buffered data exists in the printer. Press to
print the buffered data using current control
panel settings and activate the new control panel
settings.
If the printer is on a network, another user may
have changed printer control panel settings. Consult the network administrator to coordinate
changes to printer control panel settings.
Unable to select Tray 3 or Tray 4
Cause Solution
Tray 3 does not appear as an input tray option
on the configuration page or on the control panel. Tray 3 only displays as an option if it is installed.
Verify that Tray 3 is correctly installed.
Tray 3 or Tray 4 does not appear as an option in
the printer driver. Verify that the printer driver configuration
recognizes Tray 3 or Tray 4. For more
information about how to access the printer
drivers, see
