Revision 1.0

A scanner is a precision optical instrument and changing a
lamp is not like changing a household bulb. We do not
recommend that you replace the scanner lamp on your own
because of potential problems that may come up during the
lamp replacement. Technical Support personnel are not
trained in repair; therefore, if you get in trouble, assistance
in replacing the lamp is not available. Proceed at your
own risk!

Tools Needed:

 Phillips Screw Driver
 Flat Screw Driver or small pry bar
 Needle Nose Pliers

Recommended Materials

 Glass Cleaning Cloth
 Canned Air

Revision 1.0

Selecting A Work Area

It is important that you begin by planning where you will lay your disassembled parts.

 Locate an area with a workbench, table or desk with plenty of space.
 Make sure that th e area is clear of any other parts from other devices, as the many

screws and nuts can be easily confused.

 We recommend that you lay a sheet or tablecloth on the surface you will be

working on. This will prevent tools, parts and screws from sliding around and
falling to the floor. This will also prevent any parts from scratching the surface of
the work area.

Before You Start

 In order to prevent any short-circuiting of the electronic chips on the scanners

motherboard, it is very important that you ground yourself by simply touching the

metal part or parts of your PC.
Make sure that the area you touch on your PC is bare metal and not coated with paint or
plastic. This will allow for any static electricity to discharge from your body.

Note: Make sure that the scanner power cable is disconnected from the back of

the scanner at this point.

Removing the Scanner Lid

Removing the scanner lid is probably the easiest part of these instructions. Simply open
the scanner lid to a 90-degree angle and lift upward to remove the lid. (See illustration

below.)

Removing the Scanner Upper Outer Housing

 Most of our scanner models have two phillips head screws holding down the

upper housing.

You will notice the phillips screws inside of the receptacles where the scanner lid posts
(hinges) are inserted. (See illustration below.)

1. Remove the Phillips head screws inside of the receptacles where the sc anners lid posts
(hinges) were inserted.

Note: Do not use screwdrivers with magnetic or magnetized tips.

Using magnetized tools around the scanners circuit boards may

damage the circuitry, therefore rendering your scanner useless.

2. You will need to pry open the scanners upper housing. In order to do this without
damaging the scanner we will need a flat head screw driver or a very small pry bar.
Position the front of the scanner facing away from you on the workbench. (See

illustration below.)

Back of the
Scanner

3. Take your flat head screw driver or small pry bar and locate the area immediately
below the lid hinge receptacles. Take your flat head screwdriver and insert it between the
upper and lower housing. (See illustration below.)

Warning: Make sure to select an area where the scanner’s motherboard is not in

the way when you insert the screwdriver or pry bar. If you insert your prying tool

into the motherboard of the scanner you may damage the circuitry, rendering the

scanner useless.
