Yes—some edge loss is a common flatbed-scanner limitation, so the practical fix is usually to keep the original slightly in from the glass edge and use a better alignment method.

A simple approach is to place each photo or document on a larger backing sheet, such as clean ruled or grid paper, so the backing—not the original—defines the scanner position. That lets you find a platen position that scans fully while still giving you straight reference lines for alignment.

If tiny rotation corrections in software soften fine handwriting more than you want, try to get alignment as close as possible physically and accept a very small tilt rather than forcing heavy post-processing.

If full-edge capture is critical, a camera-copy setup may be better than a flatbed: mount a camera on a tripod or copy stand, use two side lights, and flatten the document with glass if needed. This avoids platen-edge cropping entirely and is often faster for large volumes or unusual paper sizes.
