44973 Exposure Head Interface EHI: checksum error in <NVS subsystem> configuration block Gravure Japanese_Newspaper_OEM_Engine Lotem_Quantum Magnus_400 Magnus_800 Magnus_VLF Slave_MCE_Firmware Thermoflex Think_Motion_Controller Trendsetter_400/800 Trendsetter_NEWS Trendsetter_Series_4 A checksum error was detected in the [head|hdm|hdp|servo_stat] nvs configuration block in the head. Every time a new value is written to the head, the appropriate checksum is calculated and written to nvs. This error is only reported when the head is initialized (ie. MPE power up). Note that this error is also generated when new head firmware is loaded. Check to make sure that all values are present and reasonable in the [head|hdm|hdp|servo_stat] blocks. If not they may still be stored in the MPE copy and can be restored with a "head nvs load" command. To clear this error, you must type "nvs save [head|hdm|hdp|servo_stat] cfg". After upgrading the head firmware from version 1.38 or earlier to version 1.56 or greater, this error may appear for the servo_stat or 20 Watt configuration block ONLY. If this is the case, and you are unable to clear it by doing an nvs save, then it is safe to disregard the error. It is due to a head/MPE incompatibility, and will not affect functionality or plot quality in any way. A device error has occurred: You may be able to continue by pressing the "resume" button onscreen (if present) or by resetting the device and workstation.

This error is reported. Faulty head NVS battery. New head firmware loaded that has new NVS parameters defined. Noisy 5 Volt line to the head.
