Your instructions are so clear and easy to follow (unlike the instruction booklet). So simple to do from the computer. Thanks so much for your calm and precise instructions. .
Sounds like the scanner bar is misaligned and out of sync .. having it repaired may cost as much as a new printer 🖨️. I dumped this model and bought the canon g7020 . Sorry I don’t have a solution for you . Good luck 🍀
sheenbean2 use school top trap to scan them to desk top . Lay the papers with print up and no crimps or creases in the stack . If you get blanks to desktop flip them the other way and run through ach top feed tray .
