Barcode Reader
Removal
The internal barcode reader assembly is used to read the barcode data supplied
with each cassette and Standard Reference Cassette (SRC). To access the
internal barcode reader, first separate the upper and lower analyzer housing
sections. Locate the barcode reader guide. Push on the latch and slide the guide
downward. The module is held in place by retaining screws which must be
removed. Disconnect cable
J14
from the main board. Pry out the window of the
barcode reader with a screw driver and remove the assembly.

Installation
Install the barcode reader module in reverse order. Make sure the replacement
barcode reader has the copper foil around the black barrel as well as a cable tie to
serve as a strain relief. Otherwise transfer these items from the old barcode reader
before installation.
Verification
Go to
DIAG2 – BCode
and swipe a cassette barcode. The cassette barcode
should appear on the display screen.
Note: the displayed barcode is preceded by one additional character (signifies
barcode type).
