Using the printer resident Web page
The Lexmark™ E120n has a resident Web page, which can be accessed from the browser. To
access the resident Web page, type the printer’s IP address in the URL address field of the browser
(for example, http://192.168.236.24). The printer’s IP address can be found on the network setup
page of the User’s Guide.
Some resident Web page features include a real-time status window of the printer and details of the
printer’s configuration, such as current memory and engine code levels. If you have administrative
rights, you can also change printer settings.
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.

Loading print media into the priority feeder
The priority feeder can be used to make quick runs of print media types or sizes not currently loaded
in Tray 1.
1 Adjust the guides to the width of the print media.
2 Place the selected print media, with the side to be printed faceup, at the center of the priority
feeder. The print media rests on the Tray 1 paper cover.
3 Push the selected print media into the printer until the print media stops.
Note: Do not force print media into the feeder. Forcing print media causes jams.
Canceling a print job
A print job can be canceled from the operator panel or from the computer. The Cancel job light
sequence appears on the operator panel when a job is canceled (see “Cancel Job/Reset printer” on
page 30 of your User’s Guide).

Clearing jams
When a jam occurs, the printer stops, and the Error light on the operator panel blinks. To determine
the location of the jam, view the secondary light sequences. Prepare the printer for jam removal by
opening the paper support and removing all printed pages from the output bin. Then, follow these
steps to clear the entire paper path.
1 Open the rear door by sliding the door release button to the right.
2 Remove any lodged print media from the paper path.
Warning: When the rear door is open, be careful not to touch the attached roller. Touching
the roller can cause contamination and affect print quality. Do not leave the rear
door open for an extended amount of time. Exposure to light will damage the blue
drum of the long-life photoconductor kit and affect print quality.

6 Close the front door by pressing firmly in the center of the front door with your thumb until the
door clicks shut.
