ABSTRACT:
A guard is used to close the gap between the print ribbon and a check supported by the platen in a check writing machine. The guard inhibits paper or metal shims from entering the gap to receive the check amount and payee data thereby protecting the printer from issuing blank checks which could later be filled out to create a counterfeit document.
