Firmware updates and recovery
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.
The device has remote firmware update (RFU) capability. Use the information in this section to upgrade
the firmware. The overall process involves the following steps:
1. Determine the current level of firmware that is installed on the device.
2. Go to the HP Web site and find out whether a firmware update is available. If an update is available,
download the latest firmware to your computer.
3. Transfer the new firmware from your computer to the device.
NOTE If after attempting to update the firmware code the device does not return to the
Ready state, perform the following procedures:
Try the firmware update again.
Perform the NVRAM init procedure. See
Service mode functions on page 226.
If the device still does not reach the Ready state, replace the formatter. See
Formatter
on page 116.
Determine the current level of firmware
The current level of firmware is shown on the configuration page. To print a configuration page, touch
Administration, touch Configuration/Status Pages, touch Configuration Page, and then touch Print.
The firmware datecode is listed in the section called Device Information. The firmware datecode has
this format: YYYYMMDD XX.XXX.X. The first string of numbers is the date, where YYYY represents the
year, MM represents the month, and DD represents the date. For example, a firmware datecode of that
begins with 20040225 represents February 25, 2004.
