Right, I understand. You need a scanner with CCD technology. Everything you can generally get at Best Buy or Staples or any other B&M store is not made with CCD. Here is a scanner that is brand new, still in production, big enough to scan a slabbed comic and also is a CCD scanner: https://epson.com/For-Work/Scanners/Document-Scanners/Epson-WorkForce-DS-50000-Color-Document-Scanner/p/B11B204121
If you want to look it up yourself, you need to find a scanner that can scan this size: Maximum Scan Area:11.7" x 17 and also has CCD as its scanning technology.
