processing, the pump is in Home position allowing Lamina to be directed
into the Flow Cell.
Evacuation Pump # 700-3820
This pump is used to:
• aspirate the sample into the pipette

Pump Cover Closed and Cassette-In-Place Detection
Three switches are located on the Pump SIC for cover-closed detection,
and for cassette-in-place detection.
The cover-closed detection senses the end of the shaft of the threaded
knob that closes the pump cover. If the knob is not fully screwed, the
pump will not run.
The Cassette-In-Place detection senses the presence of a small tab on
the cassette indicating that the cassette has been inserted into the pump.
If the tab is not detected, the pump will not run.
