Electrostatic
Protected Area
(EPA)
The EPA cover package option is available for the Type 2 Cover printer only.
Each panel on the printer is coated in a conductive layer and the panels are
electrically connected to the adjacent panel creating the Electrostatic Protected
Area. The panels are electrically grounded ensuring surface static deposition is
kept well below 100 Volts.
