the two end covers on the printer is unnecessary. The
print mechanism is hinged to the base for convenient access
to the circuit card area. To open the printer:
1.
Disconnect both the power and the interface cables.
2. Place the printer on a sturdy table or other flat
surface.
3. Turn the printer up on its back side and remove the
3 screws along the left edge of the base plate.
(These are slightly larger than the other screws in
that area.)
4. Remove 2 similar screws from the right edge of the
base plate.
5.
Set the printer back down on its base and lift the
plastic cover. Remove the
3
screws at the bottom
of the print head compartment.
