NVRAM initialization the HP Laserjet 5200 Printers
CAUTION Initializing the NVRAM resets the event log, the page counts, the EIO card, and Jetdirect Inside. Initializing the NVRAM also resets the service menu values to factory defaults.
Use the SERVICE menu to restore the page count. Also, reconfigure any computers that print to this printer so that the computers can recognize the printer. Initialize the NVRAM only when absolutely necessary. In most situations, use a cold reset rather than a NVRAM initialization to reset printer settings, because the values in the SERVICE menu are retained after a cold reset.
CAUTION Never perform a full NVRAM initialization because a significant amount of data will be lost on the formatter. Lost information will include the serial number, model number (cannot be restored), firmware code (cannot be restored), page count, and EIO and Jetdirect inside configuration information.
NOTE Before performing a NVRAM initialization, print a menu map and a configuration page. Use the information on the configuration page to reset any customer-set printer configuration values that the NVRAM initialization procedure changes.
Take special note of the total page count and the serial number.
