Manual No 25 NLB0045 01 Series NLB 9625 9645 Mini Laser Fixed Position Scanner 3 Quality of Bar Code Labels The quality of the bar code label can affect the scanning performance Poor quality labels are more difficult to decode and may result in non reads or potential misreads The bar code label should be printed to specifi cations This means that the bars are printed within spec with the correct widths no ink spread crisps edges and no voids There should be a sufficient quiet zone on both end of the bar code label For best results the paper or label stock should have a matte finish to diffuse light The print contrast signal which is a comparison of the reflectance of the bars and the background stock should be as high as practi cal Measuring Scanner Performance Two methods are helpful in determining the optimum position of the scanner The first method is to program the scanner for Trigger Disable and Continuous Read modes The scanner will be ON continuously and will continuously read the same bar code Since the buzzer sounds each time the bar code is read the sound of the buzzer can be used like a Geiger counter As the position of the scanner changes the sound of the buzzer will change The buzzer sound will be loudest and most continuous at the best reading positions The Read Rate Test The second method the Read Rate Test provides a mathematical calculation of scanning performance In this test the scanner s
