Viewing The Permanent Page Count; Setting Configuration Id; Ep Setup; Restoring Ep Factory Defaults - Lexmark W820 Service Manual

When Select is pressed after the final digit ('7' in this example), the new page count is
stored in NVRAM.

Viewing the Permanent Page Count

The permanent page count setting cannot be modified using the operator panel. It can
only be viewed using the Diagnostics menus. When Permanent Page Count is selected,
the following screen is displayed.
Perm Page Count
=1234567*

Setting Configuration ID

The Configuration ID is originally set when the printer is manufactured. However, it needs
to be reset when the CE replaces the Engine Card (which contains the NVRAM memory).
The Configuration ID can be set using the Diagnostic menus. When Configuration ID is
selected from the PRINTER SETUP menu, the current ID is displayed:
Configuration ID
=123456*
The leftmost digit ('1' in this example) blinks, indicating it is the first digit to be changed. To
change the value, press Menu until the value you want is displayed. Press Select to
move to the next digit. The next digit ('2' in this example) blinks. Continue modifying each
digit using this method. To skip a digit (that is and keep the current value), press Select.
When Select is pressed after the final digit ('6' in this example), the Configuration ID is
validated. If the ID is invalid, then Invalid ID is displayed momentarily on Line 2 before
the ID is redisplayed. If the ID is valid, then the ID is stored in NVRAM and the printer is
automatically PORed to activate the new setting.
Note: The printer is PORed into normal mode (not Diagnostics mode). If a Configuration
ID has not been set, that is, the screen has posted the "Check Config ID" status
indication, then upon entry into diagnostics, the Configuration ID setup is the only
Diagnostic function displayed until a valid ID is entered.
