    • Remove the printer from the optional second paper tray.

    • Pull out the paper tray from the front, and the duplexer from the rear.

    • Removing the print head (see the HP user guide) may also reduce the chance of ink leakage while working on the printer.

    • Rest the machine on it's rear panel, so you can access the cable.

    • Lift up the brown clamp, and pull out the cable

    • Using a T-10 Torx screwdriver, undo the two screws beneath the display (pictured)

    • The display remains attached to the scanner assembly for now. If you need to detach it from the scanner - for instance, to operate the printer while it is open - you can detach it once the scanner assembly is removed.

    • Open the door on the front of the computer, and remove the one screw on the lower left-hand side.

    • Using a spudger lever firmly outwards on the lower rear side of the panel.

    • With your other hand, push the panel backwards, It will slide half a centimeter backwards and come free.

    • Could you help me? It would be useful if you could take an image of the rear of the printer, add it to this guide, so the locations of various screws can be marked.

    • Disconnect the scanner flatfex, sheet feeder and LED cables (marked in red).

    • Remove the earth strap (marked in yellow).

    • No other cables need to be removed at this time.

    Worth checking at this point that the paper outfeed drive belt is not slack or damaged - this can give the same error message. The belt is behind the circuit board.

    • Remove the remaining screws around the top of the printer.

    • Lift the scanner assembly away from the printer.

    • If you need to detach the display, lay the scanner assembly upside down, lower the display assembly, push it to the right, and then adjust the angle of the display until it drops away from the scanner. Reconnect it to the flat-flex cable, and clip the support back into the rear to hold it. The printer will operate normally without the scanner.
