Installing and Removing Boards
The Problem
Possible Cause
Possible Solution
I loosened the screw in the
injector/ejector handle, but
the handle does not open
wide enough to remove the
board.
The screw has been
unscrewed too far,
thus blocking the
handle.
Close the injector/ejector handles,
tighten the screw and then loosen it
only until you feel a click; the
injector/ejector handle opens and the
board can be removed.
