If you lift up the lid on your scanning device you will notice a glass strip about 1 inch thick and then the large area of glass used for flatbed scanning. The 1 inch strip is used for ADF scanning. Because your papper is moving across the glass strip, any dot, smudge or scratch will affect your scanning and cause verticial lines down the page. Sometimes the dot is not visible to the eye. Get some glass cleaner that has alcohol in it and thoroughly clean the glass strip and it should solve your problem. If it turns out to be a scratch on the glass then cleaning won't help.

Sounds like it could be bad cartridge or scanner. Try replacing cartridge first cause this is pretty easy to do and is alot cheaper.

SOURCE: black vertical lines in copies
You need to clean the glass. Open up the feeder and you have a large piece of glass for scanning and to the left a smaller piece of glass that it uses to scan from the feeder. Clean this smaller piece of glass; even the slightest smudge can leave a black streak.

SOURCE: Lines on copy/scan/fax
You have something on your "scanner glass", the narrow piece of glass that the scanner "looks" through during adf use. Get some window cleaner or rubbing alcohol and clean it with a damp cloth. Often, it's correction fluid (Liquid Paper). A little dot is all it takes because the paper is traveling across the dot, effectively drawing a line down the length of the page.

Have you tried cleaning the document feeders Scan Glass? (small glass under doc feeder ~ 1" by 9") Most times there is dirt spot on this glass, causing a shadow on scans and copies.
Try copying from the large glass by lifting doc feeder / platen cover and manually placing original. If no line copying or scanning manually from large glass, then small scan glass is deffenitely the culprit. Hope this helps.
