logs while sending
results to LIS.
If you print log files from Messages
> Log files while results are being sent
to LIS, the cobas
®
4800 software
becomes unresponsive. You must be
logged on as an administrator.
If this error occurs, shut down the

Error reading
reservoir barcode
The run cannot be
continued as the
reservoir barcode
cannot be read on
the cobas x 480
instrument.
When the cobas x 480 instrument
cannot read the reagent reservoir
barcode.
Run must be aborted. Choose the
Abort button, manually remove the
sample carriers, then start a new run
with new consumables.
5
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.
It might lead to run
abort.
When a specimen barcode with
character "[" is loaded onto the
instrument.
Do not use "[" as a specimen
barcode.
7
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
If there is a barcode scanning error on
the instrument, the reload speed of the
carrier is not reduced to facilitate the
reading of the barcode again.
For information only. Scan the
barcode with the hand-held barcode
reader if needed.

(e.g. a carrier was manually removed
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.
