One possible reason that may cause this to occur is if the complete setup was not performed before printing a check. If it’s your first time printing a check using a new printer, make sure to perform the steps given in this article: Set up alignment to print checks.
After setting up your printer, it usually takes you to 4 print tabs before you can finally print them. To ensure your check set up alignment is correct.
