470 Operators Manual 72
Universal Product Code - Version E (UPC-E, send 7 digits), TCI=13
TCI 13 is the same as TCI 12 except that only the actual 7 numeric digits are used to produce
the bar code.
European Article Numbering System - Version 13 (EAN-13), TCI=20
EAN-13 is not generally used in the United States. It contains 13 digits and is constructed in
the same manner as UPC-A.
European Article Numbering System - Version 8 (EAN-8), TCI=21
EAN-8 is not generally used in the United States. It contains 8 digits and is constructed in the
same manner as EAN-13. Please note that EAN-8 does not use compression and is not a
condensed version of EAN-13 (as with UPC-A and UPC-E).
Interleaved 2 of 5 TCI=15 (I2of5)
I2of5 is a high density, variable length, numeric bar code that is used mainly in the distribution
industry. Although the data can be any length, there must always be an even number of
characters. If an odd amount of characters is required, a 0 is normally padded at the
beginning. I2of5 bar codes actually encode characters in the spaces as well as the bars.
Therefore the character spacing element (CS) must be defaulted.
Code 3 of 9 (Code 39), TCI=16
Code 39 is the most popular variable length, alphanumeric, bar code in use today. It can
encode numeric characters 0 through 9, all upper case letters, and the characters -.*$/+% and
space. Although most specifications require a specific inter character spacing, Code 39 will
allow custom inter character spacing as long as the maximum does not exceed the timeout
zone of the intended scanning equipment.
Modified Plessey (MSI 1), TCI=24
MSI is primarily used on retail self labels. It is a low density and numeric only bar code due to
the amount of space that each character consumes. MSI 2 and MSI 3 are variations which
contain 1 or 2 check digits respectively.
Postnet, TCI=36
Postnet is a numeric only bar code that is used in postal applications to sort mail.
Code 128 (Automatic Compression), TCI=40
Code 128 is a very high density, variable length, full alphanumeric bar code. It contains 3
separate character sets (A,B, and C) and separate shift characters to access them in the same
bar code. Subset C contains 99 matched numeric pairs, each encoded as a single character.
The pairing of numeric characters allows numeric portions of the bar code to consume half as
much space as they would using Subsets A or B. If TCI 40 is selected, the printer will
automatically decide which subset is most efficient and insert the appropriate shift character.
Code 128 (Manual Compression), TCI=41
This selection is the same as above TCI 40, except that the printer will not automatically select
the most efficient mode. This mode is necessary when to comply with certain industry
specifications that call for a specific subset to be used.
