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. Note: When the printer detects a Configuration ID that is not defined or invalid, the following occurs: • The default standard model Configuration ID is used instead. • Configuration ID is the only function available in DIAGNOSTICS. • Unless the menu is in DIAGNOSTICS, Check Config ID displays. 3-16 Service Manual
