1D Barcode Recognition Conditions
| Item |
Condition |
| Printed Side |
Front or back (or both, but at reduced speed) |
| Orientation |
Perpendicular (0 degrees) or parallel (90 degrees) to feeding direction
Reading direction should be specified beforehand
Note: Speed is slow when both directions are specified. |
| Size |
Line Width |
0.3 to 1mm (0.01" to 0.04")
When module exceeds 0.508 mm (0.02"), Code 128, UPC-A, UPC-E and EAN/JAN detect incorrectly |
| Code Width |
105 mm or less (4.1") (including quiet zone) |
| Bar Height |
At least 10 mm (0.4") |
| Margins |
At least one character at each end |
| Slew |
Within +/- 3 degrees |
| Element Ratio |
2.2 to 3.0 |
| PCS Value |
At least 0.60 (with at least 755 white reflectance) |
| Position |
Feed Direction |
At least 2 mm (0.1") from the edge of the page |
| Perpendicular to Feed Direction |
At least 5 mm (0.2") from the edge of the page |
| Quantity |
Up to for per page |
| Spacing |
At least 5 mm (0.2") |
| Conditions |
No background or overlapping barcodes |
* Reading accuracy is affected by the print quality of the 1D barcode. Increase the scan resolution if reading is unreliable.
