• The bar code reader was unable to read one or more bar codes on the test
cards.
• The card has passed its expiration date.
• An inconsistency was found between the information read from the button
memory on the cassette and the bar codes on the test cards. For example,
the button memory told VITEK
®
2 that a Gram negative susceptibility card
is in slot 4 of the cassette. The bar code reader, however, found that slot to
be empty.
•(Automatic dilution mode only.) The bar code reader detected a
susceptibility card for which there is no inoculum.
• The number of test cards in the cassette exceeds the number of available
slots currently in the reader carousel.
• There is an insufficient quantity of pipette tips or saline to process the
number of cards being loaded.
Workflow Considerations
For any type of load error, the VITEK
®
2 instrument backs the cassette out to
the Load Station so that you can resolve the error. If the cassette loading
door is not opened within 10 minutes, the instrument assumes that no
corrective action will be taken. The errors are ignored and the cassette is
restarted. Any test card in the cassette that has a load error will not be
processed. The cards remain in the cassette when the cassette returns to be
unloaded.
Whenever you load a cassette, the cassette icon appears on the Status
screen. You should wait until the icon disappears before leaving the
instrument.
Bar Code Read Failure
As a cassette passes through the Bar Code Reader Station, the bar code on
each test card is read. If the bar code reader is unable to read any of the bar
codes:
• The cassette is backed out to the Cassette Load Station.
• The error alarm is activated.
