SOURCE OR REFLECTIONS FROM A SURFACE.

There are four types of barcode readers that may be fitted to the machine:

• Remote Barcode Reader 1D

• Remote Barcode Reader 2D

• Handheld Barcode Reader 1D

• Handheld Barcode Reader 2D

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 and the above are single exam-

ples to demonstrate the difference between 1D and 2D barcodes.

Remote Barcode
Reader

The remote barcode reader is normally located on the input conveyor to the
machine and reads the barcode of the incoming product board.

The remote barcode reader provides GEM and SPC of the product barcode
before the product is passed to the printer. Use of the reader enables the host
program to decide on the action to be taken for this product and provides a
method for SPC to log product details for tracking.

The remote barcode reader also provides information to the Verification and
Traceability software option.

Different types of remote barcode readers may be used, a typical example is
shown below:

During the board/product transfer cycle, with the remote barcode option ena­bled, the trigger barcode scan sensor detects the board on the conveyor and
triggers the remote barcode reader to read the barcode, before the board is
passed to 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 consum­ables scanned include:

•Screen

• Print Material

• Solvent

• Cleaner Paper

• Vortex Cassette

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.
