Description
Enabled: Enables the reading of codes with a
very low code height compared to the bar width.
The following conditions can be seen as a guide-
line:
1. Bar height must be > 20 pixels.
2. Bar height must be > 2 times minimum bar
width (single width).
3. The orientation must be parallel to the axis:
Tolerance < ± 5°.
4. The print quality must be extremely good.
5. The minimum quiet zone must be > 5.5 times
minimum bar width (single width).
Note
Activation may result in decreased reading relia-
bility with codes printed according to standard.
Disabled: Only EAN-8 and EAN-13 codes with
•
correct checksum are read.
Enabled: The checksum of EAN-8 and EAN-
•
13 codes is ignored. Codes with incorrect
checksum are read.
Note
The checksum serves as a security feature to
avoid incorrect readings. Activation poses a risk
that codes with wrong contents are read or that
incorrect readings occur, e.g. as a result of poor
print quality.
Disabled: Only pharmacodes complying with
•
the requirements as to bar width/gap width ra-
tio defined in the standard are read.
Valid range: 1x bar/gap width; value between
¼ and 2/3.
Enabled: The check is deactivated. Pharma-
•
codes not complying with the standard are al-
so read.
Note
Upon activation, there is a risk that invalid codes
with wrong contents are read. Improve the print
process to adhere to the standard.
