Read the scan as the recipient will
Open the saved file, not just the scanning app's preview. Check the first and last page, then move through the entire document. Count the pages against the original and look for blank backs, duplicates or a page that has been skipped.
Rotate pages that are sideways and verify that the reading order makes sense. If two originals were captured together, make sure nothing important disappears into the fold or the shadow between them. A tight crop should not remove a date, page number or handwritten note.
Zoom to a comfortable reading size and inspect the smallest meaningful text. Numbers, decimal points and reference codes deserve particular attention. A scan that requires guesswork is not ready to send.
Check color and searchable text separately
Color may carry information in a stamp, annotation or diagram. If you converted the scan to grayscale or black and white, compare those details with the original. High contrast can make typed text clearer while erasing faint pencil marks.
Optical character recognition can make a scanned document searchable, but it can also misread characters. Adobe's scan settings include an OCR language choice because the language affects recognition. Select the appropriate language and test a few searches.
Copy a short passage into a plain text editor if accurate extraction matters. Check names and numbers against the image rather than assuming selectable text is correct. Keep the original scan image as the reference when correcting an OCR result.
Confirm the final attachment
Use a descriptive filename and remove accidental extra pages before sending. Check that the file size and format meet the recipient's requirements. If you compress the scan, inspect the reduced version again because the quality may have changed.
For sensitive material, confirm the destination address or upload portal and use the expected channel. A clear scan sent to the wrong place is still a problem.
Open the exact attachment once more from the draft or upload preview where possible. This catches the surprisingly ordinary mistake of selecting an older or incomplete copy. Keep the original paper until you know the recipient has accepted the scan and you have considered whether the original is still required.
