1.4.2. Removal of Pcb from the Mechanism.

Figure 2

Remove the Pcb by releasing the flex foil from the connector

after unscrewing the four pcb fixing screws.
Lift the small ears on each side of the flex connectors with e.g.
a small screw driver and take out the flex foil.

Make sure during (re) mounting of the flex foil that the

flex foil is inserted straight and the connector is properly closed.

1.4.3. E.S.D Measures

Figure 3

Take proper E.S.D. precautions when the Pcb is separated from
the mechanism.
Provide a short circuit clip or a paperclip to the leads of the
OPU flex foil in order to protect the laser and electrical circuitry
against E.S.D.
