We had a problem here with one of our HP 5500's where the Colour matching was incorrect. the OHT sensor clean didn't work so tried updating the Firmware and now prints perfectly.
you can download the firmware from HP and simply use the DOS "Copy" command to sent the update, very easy, and works wonders.
See the Readme for more info
