Look under the right side of the cover plate and locate the connector that
5
attaches the ribbon cable to the far right of the circuit board on the under-
side of the cover plate. Pull down on the connector to remove it.
While holding up the right side of the cover plate, slide it a few inches to the
6
right to release it. Lift up both ends of the cover plate.
7 There is now just enough slack in the cables to turn the cover plate over.
Slowly raise the far side of the cover plate and keep turning until the cover
plate is upside down and resting on the edge of the scanner housing. Do not
force the cover plate. If it does not turn over easily, swing the ends of the
cover plate back and forth as you turn it over to get more slack from the
cables.
8 With the cover plate turned over, the main circuit board is visible. The
EPROM to be changed is the smaller of two elongated chips in the middle
of the circuit board.
Using a small blade, screwdriver, or a small knife, gently pry the chip out
of the socket by sticking the blade under one end of the chip and lifting.
Then stick the blade under the other end of the chip and lift. Continue
rocking the chip back and forth until the pins come out of the socket.
While prying out the EPROM chip, be careful not to scratch the circuit

board or the other components with the blade.

in the middle of
the board.
