Reinstallation tip When you reinstall the fan, the air must flow into the printer. Verify
that the airflow arrows that are embossed on the fan body point into the printer.
CAUTION When you reinstall the fan, do not apply too much pressure to the wire-

pressure might snap off the soldered connectors on the power supply.
