High-level boot key sequences ● Skip Disk Load Use this item to initialize the device without accessing the hard disk. ● NVRAM Initialization CAUTION Initializing the NVRAM resets the serial number, the event log, the page counts, and the EIO card (initializing the NVRAM resets Service menu values to factory defaults). Use the service menu to restore the serial number and page counts. Also reconfigure any computers that print to this device so that the computers can recognize the device. Initialize the NVRAM only when absolutely necessary. In most situations, use a cold reset rather than a NVRAM initialization to reset device settings (doing so will retain the values in the Service menu). All HP Jetdirect settings will be lost. Be sure to print a configuration page before performing NVRAM initialization. Make a note of the IP address on the Jetdirect page that prints with the configuration page. You must restore the IP address after NVRAM initialization. See Configuring and verifying an IP address on page 79. NOTE Before performing a NVRAM initialization, print a menu map and a configuration page. See Use information pages on page 76. Use the information on the configuration page to reset any customer-set device configuration. Take special note of the engine cycles count, maintenance count, and the serial number. If an HP LaserJet analog fax accessory 300 is installed, performing an NVRAM initialization can cause the MFP to violate local telephone regulations. Reset the language and country/ region after performing NVRAM initialization. For more information, see the HP LaserJet Analog Fax Accessory 300 Service Manual. Use this item to initialize the device NVRAM. NVRAM initialization resets the following settings and information: ● All menu settings are reset to factory values, including the fax header and company name. ● All faxes in memory are erased. 504 Chapter 6 Troubleshooting ENWW
