After you print or try to print checks, you might be unable to use them. Unused checks sometimes must be voided, for example, when they are damaged in printing or afterward. Void the checks as follows:

1. In the appropriate payment journal, select the lines for which you ordered the printing of checks.
   
2. Click Payment status > Rejected.
   
3. The check numbers disappear from the journal.
   

Note
You can only use this procedure if the checks are not posted.

You can make sure that the checks are now void by clicking Bank > . Select the relevant bank account, click Checks, and look for checks with the value Void in the Status field.
