Check blanks printed on by mistake

Previous finance clerk put two check blanks in printer, and was called away for a minute. Ward clerk comes in and prints home teaching report on check blanks. They do not know how to void unused check numbers, so they skip them in the system. I am new finance clerk and want to fix this so Salt Lake knows that checks were ruined. How do I do this?

Cut out the signature area on the checks, destroy that part and retain the rest in your records. If the checks were never entered in MLS then you don't need to do anything to void them. See this topic in the Help Center: https://www.lds.org/help/support/voiding-check?lang=eng
