
The Scanner Unit is not secured to the printer when removing
the Upper Housing using a general screwdriver. However, when
removing the Upper Housing using the tools specified in the
check point in
p.66 , the Scanner Unit is secured to the printer;
therefore, make sure to follow the check point in the steps and
remove the screws that secure the Scanner Unit and the hinges.

It is difficult to remove/attach the cables with holding the
Scanner Unit; therefore, the following explains the procedure
while engaging the hinges without securing them by screws as
shown below. Be careful for handing them, since the hinge
sections may break easily when opening/closing the Scanner Unit.
