Printed Mono Page Count
The value of this setting enables you to gauge the amount of usage on a device. 
The Printed Page Count cannot be reset by the servicer.
Permanent Page Count
The value of this setting indicates the total number of pages that have been printed by the printer. 
The Permanent Page Count cannot be reset.

This printer setting records the printer’s serial number that was assigned by the manufacturer. When you select 
this setting, a replica of a keyboard appears on the LCD that enables you to edit the serial number.
Engine Setting 1 to 4
These settings are used by Engine code ECs to fix field problems.
Warning:  Do not change these settings unless requested to do so by your next level of support. 
Model Name
The model name can only be viewed and cannot be changed.
Configuration ID
The two configuration IDs are used to communicate information about certain areas of the printer that cannot be 
determined using hardware sensors. The configuration IDs are originally set at the manufacturer, however you 
may need to reset Configuration ID 1 or Configuration ID 2 when you replace the printer engine card assembly. 
This printer uses two Configuration IDs, each of which consists of eight digits. The first seven digits in each ID 
are hexadecimal numbers, while the last digit is a checksum of the preceding seven hexadecimal digits. Each ID 
can contain a combination of the digits 0 through 9 and the characters A to F.
If the printer’s firmware detects that either of the printer’s Configuration IDs has not been defined or is invalid, 
then the following occurs: 
1. The firmware automatically uses the Configuration IDs defined for the printer’s standard model.
2. The Configuration ID setting is the only item that appears when you open the Diagnostics menu.
3. When the printer is not in Diagnostics mode, Check Config ID appears on the LCD. 
Note:  Each of the above conditions will remain until a valid value is entered for Configuration ID 1 and 
Configuration ID 2.

The Configuration ID setting allows you to set both Configuration IDs simultaneously. To set one or both 
Configuration IDs:
1. From the PRINTER SETUP menu, touch the icon to the right of the Configuration ID menu item. The 
screen displays the value of both Configuration IDs. By default, the cursor appears on the Configuration 
ID 1 line.
2. To change the value of Configuration ID 1, touch the Backspace key to erase any of the existing 
characters. Then enter the correct ID using the number and letter keys that appear on the screen. 
3. To edit the value of Configuration ID 2, touch a section of the display screen that appears inside of the text 
box containing the current value of Configuration ID 2. The cursor appears in the text box containing the 
current value of Configuration ID 2. 
4. To change the value of Configuration ID 2, touch the Backspace key to erase any of the existing 
characters. Then enter the correct ID using the number and letter keys that appear on the screen. 
Note:  To exit the Configuration ID screen and return to the PRINTER SETUP menu, touch Back. 
Note:  Although it is recommended that all unused and reserved bits be set to zero, the code will not validate or 
enforce this condition. 
5. To save the values of both Configuration IDs, touch Submit. The printer validates both IDs. If either ID is 
invalid, the printer posts Invalid ID, discards any changes, and displays the original Configuration IDs. If 
both IDs are valid, the printer automatically returns to the PRINTER SETUP menu. 
EVENT LOG
The exact number of events recorded in the Event Log will vary since each event requires a different amount of 
storage space. When the Event Log requires more space to record an event, it overwrites the oldest currently 
logged event(s) and inserts the new event into the first log position. Consecutive log entries may be identical if 
the same event occurred twice in a row.
The Event Log records the following types of events:
•All 9xx Service Errors
•2xx Paper Jams
