This issue is most likely due to the TC75 device not having the latest imager firmware. You can check your imager firmware version through DataWedge under "DataWedge -> Menu -> About -> 2D Barcode Imager:"
The 2D Barcode Imager field should show version PAABVC02-001-R00 if you have the correct version. If you don't see the "2D Barcode Imager" field in the About settings menu then you may need to update the BSP on your device to see this field.
Please confirm which version of firmware you have.
You can find the TC75 imager firmware update utility here:
yep, this helped, thanks a lot!
