(3) Precautions when using code 128
● The 2 modes include Code set B (Alphanumeric, numbers, symbols) and Code set C (numbers only).
The mode can be changed by pressing "Code B" or "Code C" on the keyboard.
● In the case of continuous numbers, the bar can be shortened by setting to code set C.
● When printing in 2 lines or more, only one "code 128" can be set for one column.
If you attempt to set more than one "code 128" for the same row, an "illegal bar code 2" error occurs.
●When code set was changed over, return to the original code set.
(Example)
1 Code set B: ABCD<C>0123<B>
2
Code set C: 0123<B>ABCD<C>45<B>EF<C>
<B>, <C>: Code set changeover keys
(4) Precautions when using DM code
● Set as shown below for print item to which DM is to be set:
(i) Number of lines : 1 line
(ii) Character size : 5
● Set barcode type on the print format screen.

(The number of characters that can be coded differs according to the numbers/characters string.)
(Note 1) Use the number of vertical dots provided in the table for speed calculation.
[Rules for calculating number of digits]
Alphabetical characters are treated as one digit per character.
Single independent numbers are treated as one digit per number.
In the case of consecutive numbers, two numbers are treated as one digit.
If a single number is left over, it is treated as one digit.
The total is within 12 digits for 16
