Platen down on safety latches and won't move

When platen is lowered onto safety latches, the platen may not respond to up/down switch.

Press the 'Emergency Platen Up' button to get the platen to move up off of the latches.

Turn the key switch to run to disengage the latches. If this does not work, you can manually retract the latches by plunging the 7CR contactor.
