IMPORTANT NOTICE TO USERS:

A scanner is a precision optical instrument. The manufacturer strongly recommends that
trained service personnel perform any and all repairs dealing with the disassembly and
reassembly of any fastened parts. Microtek does not have (live) or email technical support
staff to assist with scanner upper housing disassembly or reassembly. By following these
instructions you agree and acknowledge that neither the manufacturer nor its dealers and
resellers shall assume liability or responsibility for any damage to a scanner unit or personal
injury caused by untrained service personnel or other failure to closely follow the detailed
Glass Cleaning Instructions. Proceed solely at your own risk!

 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.

Scanner Disassembly Procedures

Before carrying out any of the procedures described in this document, make sure that the scanner has
been turned off and the power cord has been disconnected.

To prevent any chance of electric shock, the scanner housing should only be opened by a qualified
electronics technician, and only after the scanner has been disconnected from the power source.

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

Removing the scanner lid and scanner glass bed:

1. Turn off the power and unplug the power cord from the back of the scanner.

2. Open the scanner lid to a 90° angle as illustrated below.

3. Lift the lid upward to remove it. See illustration below:

Notice how nothing attaches
the lid down to the scanner.
The lid hinges should release
very easily from the female
receptacles.
Note: Keep in mind that the
lid hinges are especially
designed to release only when
the lid is at a 90° angle.

Special hinge design is rounded at the
tip as illustrated below
