Labcyte Echo 520 User Manual page 71

The location of each scanner depends on the location of your barcode
labels on the microplates. You can use either the front scanner or the side
scanner, but not both at the same time.
Note: Several terms are used to specify barcode locations on a
microplate. Standing in front of an Echo liquid handler, the two
readable barcode locations are identified as follows:
Figure 3.14 Barcode label locations
Left, short, or
west position
Note: Always place side barcode labels on the left side of both source
and destination microplates. The Echo liquid handler uses the left
barcode scanner to read the barcode on the source plate, but uses the
right barcode scanner to read the barcode on the destination plate—
after it is inverted.
