Cleaning the Electrodes, Pre-punchers and Insulation Plate
Reinstalling the Pre-punchers
1 Carefully insert the pre-puncher (labeled 8) in the outlet lift. Connect the
tube to its connector (labeled 8) if you run applications in the CE+p and
CEC mode. The fitting of the outlet pre-puncher must be tight. Otherwise,
problems may occur during CEC mode.
NOTE
If you do not run applications in CE+p and CEC mode, keep the tube disconnected and fix
the tubing in such way that it does not disturb the movement of the inlet lifter.
