You selected one check stock type, assigned check numbers, then switched to a different stock type before printing. The checks printed with the wrong format. This is expected behavior. Here is why it happens and how to fix it. --- ### How the Check Template Works The check template is set at the time you assign check numbers, not at the time you click Print Checks. When you assign check numbers, the system uses whichever stock type is selected at that moment. That selection locks in three things: - **Where the number comes from.** On blank stock, the system assigns the next number in its own internal sequence. On pre-printed stock, the number must match the number already printed on the physical check. - **The numbering rules.** A blank stock number that is not used creates a permanent gap in the sequence and cannot be reused. A pre-printed number can be entered again. - **The check layout.** This includes whether the system prints the check number and MICR line or relies on what is already printed on the physical stock. --- ### Why Switching After Assignment Does Not Work If you switch the Pre-Printed Checks button after check numbers have already been assigned, those numbers were already created under the first stock type’s rules. Changing the button at that point does not update the template for the assigned checks. The checks will still print using the stock type that was selected when the numbers were assigned. If the system applied the new template at print time without reassigning the numbers, it could produce checks where the number on the system does not match the number physically printed on the check stock. This would cause problems with your check register, Positive Pay file, and bank reconciliation. --- ### What to Do If You Selected the Wrong Stock Type If you realize you selected the wrong stock type after assigning check numbers, do not just switch the button and print. You need to reassign the check numbers first. Follow these steps: 1. Select the correct Pre-Printed Checks button 2. Select all of the already assigned checks 3. Reassign the check numbers 4. Print Once the numbers are reassigned under the correct stock type, the checks will print with the correct template and format. --- ### What Happens If I Already Printed With the Wrong Template? If the checks have already been printed with the wrong format, you will need to void and reissue them. Follow these steps: 1. Go to **Payments \> Forms \> Void Reissue Form** 2. Select **Void/Reissue Issued Payment** 3. Search for the affected check and select it 4. In the Action dropdown, choose **Reissue Check** 5. Complete the form and submit it for approval 6. Once approved, the reissued check will appear in Check Batch Processing 7. Before assigning check numbers, make sure to select the **correct Pre-Printed Checks button first** 8. Assign the check numbers and print Selecting the correct stock type button before assigning the new check numbers is the most important step. This ensures the reissued check prints with the correct format. --- ### Quick Summary | Situation | What to Do | | --- | --- | | Wrong stock type selected before assigning numbers | Switch to the correct button first, then assign numbers | | Wrong stock type realized after assigning numbers but before printing | Switch to the correct button, select assigned checks, reassign numbers, then print | | Checks already printed with wrong format | Use the Void and Reissue Form, choose Reissue Check, then select the correct button before assigning new check numbers | ### Need Help If you have questions about check stock types or check number assignment, contact the Aclarian Client Support team for assistance. -
