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.
When the printer is not in Diagnostics mode, Check Config ID appears on the LCD.
3.
Note: Each of the above conditions will remain until a valid value is entered for Configuration ID 1 and
Configuration ID 2.
