Scanner Disassembly Procedures

Tools Needed:

 Phillips Screw Driver or 8mm Allen Wrench
 Flat Screw Driver or small pry bar
 Needle Nose Pliers

Recommended Materials:

 Glass Cleaning Cloth
 Clear streak-free glass cleaner

• Canned Air

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 the 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.

Reminder: Make sure that the scanner power cable is disconnected from the back of the scanner at this
point.

Note: Care should be taken throughout all disassembly and reassembly procedures never to smudge or
soil the lens or either mirror.

Special Note: This is an opportunity to clean the scanners glass bed. Place the scanners upper
housing on a flat surface with a cloth or towel underneath to prevent scratching on the glass while
clean the glass.

Cleaning Tip: The best way to clean the scanner glass bed is with a clear glass cleaner solution.
Make sure you do not use the blue, red, yellow or any other color dye solutions. Using color dye
solutions can form streaks on the scanners glass bed. Use the clear solutions for best results. You
can also use a 50/50 solution mix distilled water and pure alcohol. Also use a soft cloth and avoid
all abrasive material such as sponges and rough paper towels. Spray or moisten the cloth. Do not
spray directly on the scanner upper housing glass, as there is a calibration strip on the underside of
the glass bed that when stained affects scans adversely.

Reassembling the Scanners Upper Housing:

1. Close the scanner upper housing and align the tabs on the bottom of the upper housing with the

slots at the front and rear of the base.

2. Then re tighten the four screws with a screwdriver.
