    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.

    Important:

    Make sure that all of the shipping materials (for example shipping tape) are removed from the replacement part prior to installation.

    Note:

    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.

  3. To install an assembly, reverse the removal steps.

    Note:

    When applicable, special installation instructions are provided for an assembly at the end of the removal procedure. Always completely read the removal instructions and follow all special installation instructions.
