Configuration Id; Itu Barcode - Lexmark C540n Service Manual

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 factory when the printer is
manufactured. However, the servicer may need to reset Configuration ID 1 or Configuration ID 2 whenever the
system board is replaced. The IDs consist of eight digits. The first seven digits in each ID are hexadecimal
numbers, while the last digit is a checksum of the preceding seven digits. Each ID can contain a combination of
the digits 0 through 9, and A through F.
