Engineering Details Remote firmware updates The HP Color LaserJet CP4005 printer features remote firmware update (RFU) capability. The method for downloading remote firmware updates from the Web site is similar to that used to download the latest printing-system software and print drivers.

(Also, print a menu map to see what user settings have been configured.) 2. Go to the HP Web site and download the latest firmware to the computer. 3. Download the new firmware to the printer. (Print a new menu map to compare user settings between the previous firmware and upgraded firmware.)
