Zebra DS457 User Manual

Symbologies 12 - 95
Intercharacter Gap Size
Parameter # 381 (SSI # F0h, 7Dh)
The Code 39 and Codabar symbologies have an intercharacter gap that is typically quite small. Due to various
bar code-printing technologies, this gap can grow larger than the maximum size allowed, preventing the
imager from decoding the symbol. If this problem occurs, scan the Large Intercharacter Gaps parameter to
tolerate these out-of-specification bar codes.
