Partial used tip rack The tip pickup
algorithm may
generate multiple
partially used tip
racks.
After multiple 96 batch size runs are
performed continuously.
Load partial pipette tip racks when
performing smaller batch sizes runs
(e.g. 24, 48 and 72) in between the 96
batch size runs.
6
"[" in code 128 not
supported
Character "[" in
code 128 is not
supported for the
specimen barcode.

abort.
When a specimen barcode with
character "[" is loaded onto the
instrument.
Do not use "[" as a specimen
barcode.

Barcode scanning
reload speed
The barcode
scanning reload
speed during error
recovery is reduced
in software version
1.x but not in
software version
2.1

from of the instrument during the
sample preparation process).
If a run is aborted by the system or a
user, before starting the next run,
check the tip eject plate slot for
pipette tips. Manually remove and
dispose of the pipette tips if needed.
