Bar Code Validation Demo Page
9.The printer will print one demo page containing two good bar codes.
NOTE: In the QUICK SETUP or MEDIA CONTROL menu, if Label Length is set between 0.5 and 1.0 inches, only one good bar code will print.
If Label Length is less than 0.5 inches and Label Width is less than 2.0 inches, no demo page will print.
10.To demonstrate a bad bar code reading, block the scanning beam with an opaque object while the bar code moves under the beam. When you block the beam, the validator will generate a reading error and will perform a default error action. The default setting for the Validator Action in the VALIDATOR menu is Retry Form.
