Unclamping There are two unclamping states, there is unclamping with the board retained
by the OTC plate and unclamping with the board released. The two modes of
operation are programmed via the software. The parameter, OTS Retain Mode,
if enabled, allows the board to be held during the unclamping phase of the cycle
If disabled, the clamp is retracted preventing the possibility of smudging the
print. This is the default setting.
