Be careful not to touch the fuser, which is marked CAUTION
Hot Surface Avoid Contact. If the printer has been in use, the
fuser can be very hot.
CAUTION Hot Surface Avoid Contact
Avoid touching the components inside the printer unless
instructed to do so in this guide.
Never force the printer's components into place. Although the
printer is designed to be sturdy, rough handling can damage it.
Be sure not to scratch the surface of the drum. When you
remove the imaging cartridge from the printer, always set the
unit on a clean, smooth surface. Also, avoid touching the
drum, since oils from your skin can permanently damage its
surface and may affect print quality.
Do not turn the cartridge upside down or stand it on its sides.
