6.8 TASK - - FAN REPLACEMENT

Full functioning of all fans is essential to the operation of the scanner because overheating can damage the unit.

Three fan AC fans are mounted in the CF series scanners to dissipate the heat produced by the lamps and the electronic hardware. One of these fans is mounted on the back cover of the scanner; one is mounted underneath the Multibus card cage; and one is mounted above the power supply.

Quick connect clips can be easily pulled off and pushed on the fan terminals to disconnect and reconnect the power supply wires to each fan.

Equipment, Tools & Materials Required:

•5/32-inch Allen wrench

•Standard Flat-head Screwdriver

Procedure for Replacing Fans:

1.Disconnect the power completely; remove the AC power cord.

2.Remove the screws and save all the hardware for installing the new fan later.

3.Place the new fan in position and connect all the wires.
