Error code
Error message
Description
Found m instead of the expected number of
1D/2D codes in step n
Only m codes instead of the expected number of
codes were found in step # n during multicode decod-
Maximum number of codes per image (m) was
exceeded in step n
More than the maximum possible number of codes per
image was found with multicode decoding (50,
The maximum amount of data which can be de-
coded was exceeded in code m of step n
A maximum of 3001 bytes can be decoded per step.
This length was exceeded in step #n for code #m.
Trigger during image acquisition
The trigger signal was applied during image acquisi-
tion. In this case, no additional image acquisition is
started. Instead, image acquisition and processing are
continued and an "N_OK" result is generated immedi-
Step timeout reached in step n
In step #n, the defined time limit was reached.
OCR: No text was found in step #n.
Text length is less than minimum specified in step
n
OCR: The text found in step #n is shorter than the
minimum setting.
Text length exceeds the maximum specified in
step n
OCR: The text found in step #n is longer than the max-
imum setting.
Quality violates limit values in step n
OCR: The text found in step #n is below the quality
threshold setting.
OCR: The match performed in step #n was not success-
ful.
Reference text missing in step n
OCR: There is no string specification available for
step #n.
Verification failed in step n
The read code could not be verified.
Verification for code type found in step n not
supported
The selected verification method is not supported for
the code type found in step #n.
Mean light outside of range in step n: Maximum
exposure time reached
The average brightness needed for ISO/IEC 29158 is
outside the valid range (see Error code 4709).
The specified maximum value for the exposure time
was reached during automatic exposure control.
To resolve this error:
1. Use brighter lighting or enlarge the aperture of the
objective (lower aperture number).
Perform a new calibration.
Mean light outside of range in step n: Cycle time
limit of the automatic exposure control reached
The average brightness needed for ISO/IEC 29158 is
outside the valid range (see Error code 4709).
The automatic exposure control was unsuccessful
because the necessary decodings could not be com-
pleted within the time limit.
To resolve this error:
• Reduce the exposure ROI of the program.
• Increase the time limit of the exposure control.
• Also ensure that the code is completely within the
exposure ROI until conclusion of the image acquisi-
tion process.
Mean light outside of range in step n
The average brightness needed for ISO/IEC 29158 is
outside the valid range (70% to 86%) in step #n.
