Indicator lights
If your printer lights look like this
when you double-click the operator
panel button:
Then your printer:
has an error communicating with the host computer (Host Interface
Error).
This error is displayed if:
you have an external print server connected to your printer, but
your printer can’t detect it when you first turn the printer on, or
the computer attempts to communicate with the printer through
the parallel port, but the port setting has been disabled in
configuration mode, or
the computer attempts to communicate with the printer through
the USB port, but the port has been disabled in configuration
mode.
If this error occurs when you turn on the printer, double check that
the ENA is still plugged in to the printer.
If you want to print through the parallel port, print a menu settings
page (see Printing a test page) to verify that the parallel buffer
setting is disabled. Re-enable the parallel port in configuration
mode (see the table on page 69).
If you’re printing through the USB port, print a menu settings page
(see Printing a test page) to verify that the USB buffer setting is
disabled. Re-enable the USB port in configuration mode (see the
table on page 76).
