8. Press the ↵ key to print and validate the demo page. (If the ↵
key is locked, unlock it by pressing ↓ and ↵ together. This key
combination can be changed by the user. Use the correct key
combination if it was changed.)
9. The printer will make three demo pages, and each page
contains two good bar codes. To demonstrate the 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" under validator menu is Reprint Form.
10. Print the validation report to ensure the barcodes are validated
correctly.
11. Relock by pressing ↓ and ↵ together, then press PAUSE to put
the printer back online.
