Your suggestion did the trick! For those who tried this and it did not work, be aware the platen is divided. At first this did not work for me, and then I noticed the platen glass is divided. My smudge was on the left part of the glass. I immediately noticed there was something adhered to the platen. I cleaned this section, and my issue has been resolved. No more black lines down my scanned documents!
