2. Unpack the replacement part from the packaging.
CAUTION: 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 or before touching rollers or
pads.
IMPORTANT: Make sure that all of the shipping materials (for example shipping tape) are removed
from the replacement part prior to installation.
Step 8: Install the power supply
1. After installing the power supply, make sure that the locator pins t into the holes on the assembly
(callout 1).
TIP: It might be easier to t the pins in the holes if two screws (callout 2) are loosened so that the
black plastic bracket behind the power supply can be adjusted.
