Replacing the (Square) IR Filter
IMPORTANT: The IR filter is made of glass and is expensive to replace. It is not
included in the product warranty or service contract. Use care
when handling the IR filter.
Wear white cotton gloves for this procedure.
It is not necessary to power down the scanner before changing the IR filter.
1. Open the lamp-and-filter-access door (see page 4-6 for the location of the
lamp-and-filter-access door).
2. Loosen the thumbscrews on the lamp cover and pull the cover straight out.
When you remove the cover, the safety switch is released, removing power to
the lamp socket.
CAUTION: Wait at least five minutes for the lamp to cool.
