Printer Control Panel Problems
Control panel settings work incorrectly
Problem 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 power switch to
turn the printer on.
Printer settings in your software application or
printer driver are different from the printer
control panel settings. Settings in your software application or printer
driver override printer control panel settings.
Verify that the settings in your software
application or printer driver are correct.
Control panel settings were not correctly saved
after they were changed. Reselect the control panel settings and then
press [Select]. An asterisk (*) should appear to
the right of the setting.
The Data indicator is lit and there are no pages
printing. Buffered data exists in the printer. Pressing
[Go] prints the buffered data using current
control panel settings and then activates the
new control panel settings.
If you are on a network, another user may
have changed printer control panel settings. Consult your network administrator to
coordinate changes to printer control panel
settings.
Unable to select Tray 3 (optional 500-sheet paper feeder)
Problem Solution
Tray 3 (500-sheet paper feeder) does not
appear as an input tray option. Tray 3 only displays as an option if it is
installed. Verify that Tray 3 is correctly
installed. Verify that the printer driver has been
configured to recognize Tray 3.
