CAUTION
To prevent electrostatic damage to electronic components, always wear
a grounded static wrist strap when you handle circuit boards.

printer frame. Touch the printer frame with the hand wearing the wrist
strap before you touch electronic components or the controller board.
4. Remove the screw securing the CT board connector plate to the rear of
the card cage. (See page 358, item 4.)
