How do I know if I have placed my strips in the carrier properly?

Tail pads should be cut off just above the colored bottom arrow tape. Strips or combs should be placed face down with the barcode closest to the tester. The paddle should slide into the QuickScan with some minimal resistance until it stops. When the paddle is properly positioned, the curvature of the silver QuickScan cover and black paddle should align.
