To avoid truncation errors, the scanner can be programmed to only decode bar codes of one specific length, i.e., containing a specific number of digits. It is also possible to program the scanner to only decode bar codes of either of two specific lengths.

To fix two (2) lengths (or number

of digits) of bar code for all symbologies:

1.Scan “START” to enter the programming mode

2.Scan “Enable fixation(H1) for all symbologies” bar code

3.Scan a sample bar code of the desired length

4.Repeat Step #3, re-scanning

the sample bar code (this may be the same as the first one)

5.Scan “END” to exit the programming mode

To fix one (1) or two (2) different lengths of bar codes for selected symbologies:

1.Scan “START” to enter the programming mode

2.Scan “Enable fixation(HK) for selected symbologies” bar code

3.Scan a sample bar code of the desired length #1

4a. Go to step 5 or

4b. Scan a sample bar code of the desired length #2

5.Scan “END” to exit the programming mode

“Fixing the Number of Digits” can only be applied to Code 39, NW-7, 2 of 5, MSI/Plessey. WPC, Code 93, IATA, Code 128 are not affected.

Setting Minimum/Maximum Length

This option modifies the default minimum length table. To use this option, perform the following steps:

1.Scan “START” to enter the programming mode

2.Scan “Enable minimum length for selected codes” (HL)

3.Scan bar codes of the required type and length.

4.Scan “END” to end the programming sequence.
