Flatbed optical unit operation The ADF optical unit is located 26.5 mm (1 inch) from the flatbed optical unit when the flatbed optical unit is in the ADF scanning position. When a two-sided original document is copied from the ADF, the first side begins copying before the second side of the two-sided copy. Note The mechanical lock on the HP LaserJet 9000mfp is not located in the “home position.” Locking the carriage in the control panel moves the optical unit into position so the mechanical lock, which is located on the left side of the unit, can hold the flatbed optical unit during a move. To lock the carriage:
1 Touch MENU 2 Touch CONFIGURE DEVICE 3 Touch RESETS 4 Touch LOCK CARRIAGE 5 Engage the mechanical lock CAUTION Always engage the mechanical lock before moving the HP LaserJet 9000mfp to avoid damaging the flatbed optical unit.
