Quick Reference

Understanding the Operator Panel

The printer operator panel has two buttons and two lights. Lights indicate the status of the printer.
Buttons are used to continue or cancel the current print job.

When the printer is turned on, both lights cycle as a self test is performed. Also, when the printer is
reset, or when a printer setting is changed in the menus, both lights cycle.

• Press and release Continue to resume printing.

• Press and release Continue twice quickly to display the secondary light sequence.

• Press Continue from the Ready state to print the menu settings page.

• Press and hold Cancel to cancel the current job.

• Press and hold Cancel until both lights come on to reset the printer.

Understanding the operator panel lights

The operator panel lights mean different things, depending on their sequence. Lights that are off, on,
and/or blinking indicate printer conditions such as printer status, intervention, or service.

Use the light sequence table to find the message being indicated, then click the message for more
information.

Printing the menu settings and network setup page

Printing the menu settings and network setup page

To print the menu settings and network setup pages, press from the Ready state. The printer
automatically prints the menu settings and network setup pages.

A list of the printer settings and the current default values are printed on the menu settings page. The
current default settings are marked with an asterisk. The network setup page confirms the network
Status is “Connected” and lists the current network settings.

Restoring factory defaults

This function will return most of the settings back to their factory values. The display language and
the settings in the Network and USB menus are not returned to the factory defaults.

To restore the printer to the original factory defaults, press and hold for more than three
seconds.

Note: Before restoring the factory defaults, make sure the host computer or network has

stopped sending information to the printer.
