CHAPTER 32 BARCODE READER AND VERIFICATION AND TRACEABILITY
OVERVIEW
There are two types of barcode readers that may be fitted to the machine:
• Remote Barcode Reader
• Handheld Barcode Reader
1D or one dimensional barcodes are the most common barcodes consisting of
a single row of different width bars.
2D or two dimensional barcodes consist of square modules constructed in a
matrix that may be square or rectangular.
NOTE
There are many different formats of barcodes: Data matrix, Aztec, QR, PDF
417. In the graphics above, these are single examples to demonstrate the
difference between 1D and 2D barcodes.

CAUTION
LASER CONTROLS AND ADJUSTMENTS. USE OF CONTROLS OR
ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
CAUTION
RADIATION. RISK OF INJURY TO THE EYES DUE TO LASER LIGHT BEING
PRESENT IN THE VICINITY OF THE LABEL. DO NOT LOOK AT THE LIGHT
SOURCE OR REFLECTIONS FROM A SURFACE.
CAUTION
EQUIPMENT SERVICING. THE LASER DOES NOT CONTAIN USER
SERVICEABLE PARTS. OPENING THE UNIT COULD CAUSE MIS-ALIGNMENT OF
THE LASER, THIS MAY MAKE THE EQUIPMENT DANGEROUS TO OPERATE.
Remote Barcode
Reader
The remote barcode reader is located on the input conveyor to the printer and
reads the barcode of the incoming product. It also provides information to the
Verification and Traceability software option.
The system comprises a mounting stand, the reader, a suitable barcode on the
product (not shown), an in-line trigger sensor and a set of configuration cards.
The stand is mounted onto a customer’s input conveyor. The configuration
cards are used to aid the barcode reader set up and calibration. The sensor is
attached forward of the reader using a Velcro fastener.
During the board/product transfer cycle, with the remote barcode option ena-
bled, the trigger sensor detects the board on the conveyor; it triggers the remote
barcode reader to read the barcode, before the board is passed into the printer.

Handheld Barcode
Reader
The primary function of the handheld barcode reader is to scan consumables
and user information for the Verification and Traceability software. The consum-
ables scanned include:
• Stencil
• Print Material
• Solvent
• Cleaner Paper
The handheld barcode reader may also be used to scan the first board of a
batch that is to be checked by the remote barcode reader during a print run.
Different types of handheld barcode readers may be used, the user can select
a reader of their choice. It must be capable of being connected to an available
USB port on the printer.
