No, the junk characters are not the same as scanning errors or typing errors or spelling errors found in the hard copy text. Garbled up text and extraneous junk characters are not there in the original print. We are talking orders of magnitude difference in quantity of errors here. If you start scanning books yourself, I think you'll soon discover the difference between the typical ocr error, or the junk character on the one hand, and the uncaught typo or spelling error on the other.
