HP Z840 Workstation Series User Guide

Cleaning the mouse
1. Follow the safety precautions in the Maintenance and Service Guide for your workstation before
cleaning the mouse.
2. If the mouse has an on/off switch, turn it off.
3. Wipe the body of the mouse with a soft microfiber cloth or chamois moistened with alcohol-free glass
cleaning fluid or water with mild soap solution.
4. Note these guidelines:
●
Laser or light: use a cotton swab dampened with cleaning solution to gently brush out any dust
around the laser or light, and then wipe again with a dry swab. Do not wipe the laser or light
directly with the swab.
●
Scroll wheel: spray canned, pressurized air into the gap between the scroll wheel and the click
buttons. To avoid condensation, do not blow air directly on one spot for an extended period.
●
Roller ball: remove and clean the roller ball, remove any debris from the ball socket, wipe out the
socket with a dry cloth, and reassemble the mouse.
