Process notes, cautions, and miscellaneous Support information ● SKUs are shipped at the slowest speed. ● LPDC: Engine speed should be set when the printer is unboxed and first installed. ● Engine speed configuration is provided from HP cloud service as an LPDC license. - The license contains values of the model name and speed that are stored on the Formatter. - The license is signed by HP and validated by firmware. - The license is locked to a specific printer via HP immutable identity and HP serial number that cannot be changed. - The printer will continue to look for speed setting until set for 10 minutes after the device has come to a Ready state. Each time the device is rebooted until it completes a successful LPDC process. - NOTE: Printer checks for USB after start up once after entering UI ready. NOTE: Printer checks the cloud once per minute for ten minutes after the USB check. - HP immutable identity is tied to a private key and secured on a trusted platform module (TPM) on the printer MSOK. - Printer automatically obtains license from an HP Cloud Server when first turned on and connected to the internet. - The printer will continue to look for speed setting for 10 minutes after the device has come to a Ready state. Each time the device is rebooted it will look for speed until it completes a successful LPDC process. ● After the LPD license is installed, all customer settings on the printer are set back to the factory defaults. 60 Chapter 6 Late point differentiation configuration (LPDC) ENWW
