Report "I have a Wasp WLR 8900 hand held wired scanner and it will no longer scan. I have tried the factory reset only to have it beep when scanning a bar code in the users manual but still will not scan my system generated bar code. I can set it so the scanner stays on but if I have it set for button use I have to hold the button in order for the light to show. is there a setting I am missing from the user manual or is it garbage?"
