Installation procedure
Make sure that you follow these instructions carefully. The installation process is

simple, but if done incorrectly, your scanner could be damaged. If you would like
assistance with this procedure, or would rather have a Microtek technician install
the EPROM, call Microtek technical support.
You will need a Phillips screwdriver to open the scanner, as well as a small
blade, screwdriver, or knife to remove the old EPROM.
Turn off the scanner and disconnect the SCSI cable and power cable.

2 Touch the metal frame of your desk or some other large metal object nearby
to discharge any static electricity your body may have built up. This is
important, as static electricity is harmful to the delicate electronics inside
the scanner.
3 Turn the scanner upside down with the back end of the scanner to your
right. Then remove the four screws that hold the metal cover plate to the
bottom of the scanner housing.
There are cables that connect components in the scanner to the circuit

board on the cover plate. When lifting the cover plate, do not pull hard
because it could accidentally disconnect some of the cables.
4 With the back end of the scanner oriented to your right, lift up the right
side of the cover plate slowly until you feel the pull of the cables that
connect it to the inside of the scanner. You will not be able to lift it more
than 6 or 8 inches.
The EPROM to be changed is located on the underside of the cover plate.
To get enough slack in the cables to turn the cover plate over, disconnect
the ribbon cable on the far right. This is a gray ribbon cable with a black
connector that plugs straight into the circuit board.
