BARADJUST
Chapter 2 Program Instructions
Field of Application Statement for enabling/disabling automatic adjustment of bar code
position in order to avoid faulty printhead dots.
Syntax BARADJUST,
1 2

Default:
is the maximum left offset (No. of dots).
is the maximum right offset (No. of dots).
0,0 (i.e. BARADJUST disabled)
Remarks Under unfortunate circumstances, a printer may have to be run for some time
with a faulty printhead, before a replacement printhead can be installed.
Single faulty dots will produce very thin "white" lines along the paper web.
This may be tolerable for text, graphics and vertical (ladder) bar codes, but
for horizontal bar codes (picket fence), this condition is likely to render the
bar code unreadable.
If the bar code is moved slightly to the left or right, the trace of a faulty dot
may come between the bars of the bar code and the symptom – if not the cause
– is remedied for the time being.
The BARADJUST statement allows the Intermec Fingerprint firmware to
automatically readjust the bar code position within certain limits, when a
faulty dot is detected (see HEAD function) and marked as faulty (see SET
FAULTY DOT statement). The maximum deviation from the original
position, as specified by the PRPOS statement, can be set up separately for
the directions left and right. Setting both parameters to 0 (zero) will disable
BARADJUST.
The BARADJUST statement does not work with:
• Vertically printed bar codes (ladder style).
• Stacked bar codes (e.g. Code 16K)
• Bar codes with horizontal lines (e.g. DUN-14/16)
• EAN/UPC-codes (interpretation not repositioned)
Examples Enabling BARADJUST within 10 dots to the left and 5 dots to the right of the
original position for a specific bar code, then disabling it:
10 BARADJUST 10,5
20 PRPOS 30,100
30 BARSET "CODE39",2,1,3,120
40 BARFONT ON
50 PRBAR "ABC"
60 BARADJUST 0,0
70 PRINTFEED
