Updating the firmware code Note If after attempting to update the firmware code the device does not return to the Ready state, preform the following procedures. Try the firmware update again. Perform the NVRAM init procedure. See NVRAM init. If the device still does not reach the Ready state, replace the formatter. See Formatter and line interface unit (LIU). The device uses a flash-memory-based formatter that enables the firmware code to be updated when updated firmware is available. Flash memory also provides a method for product recovery if the installed firmware becomes corrupted or fails. Print a configuration page to find out what version of firmware code is installed on the device. If updated firmware is available, download the appropriate update (www.hp.com/support/ lj3015; www.hp.com/support/lj3020; www.hp.com/support/lj3030) and follow the instructions in the ReadMe file. 240 Chapter 6 Troubleshooting ENWW
