    1. Dispose of the defective part.
        note:
      HP recommends responsible disposal of the defective part.
    2. Unpack the replacement part from the packaging.
        caution:
      Some parts are sensitive to electrostatic discharge (ESD). Always perform service work at an ESD-protected workstation or mat. If an ESD workstation or mat is not available, touch the sheet-metal chassis to provide a static ground before touching an ESD-sensitive assembly. Protect the ESD-sensitive assemblies by placing them in ESD pouches when they are out of the printer.
      If the replacement part is a roller or pad, avoid touching the spongy part of it. Skin oils on the roller or pad can cause paper pickup and/or print-quality problems. HP recommends using disposable gloves when handling rollers or pads or washing your hands before touching rollers or pads.
        note:
      Make sure that all of the shipping materials (for example shipping tape) are removed from the replacement part prior to installation.
    3. To install an assembly, reverse the removal steps.
