How to get rid of a black strip (1") on the leading edge of scanned documents?

We are getting a black strip on the leading edge of the 8.5 x 11 documents, and it cuts off the bottom of the image, unless we scan all documents as legal. Rollers have been changed, and glass cleaned.

You must be using Auto contrast/brightness. Change to manual, try one or two scans changing the brightness tab moving left or right and choose desire output quality. Remember the settings for that set of documents. The brightness will vary depending upon data (foreground) and noise (background). For a different set of docs you may need to adjust the settings slightly.

The black lines are caused by either marks on the scanning strip or a fault with the scanner. If there are no marks on the scanning strip then there's nothing that can be done without sending it for repair. Details of the cleaning procedure are shown in the instruction manual.

Sounds like the shading compensation strips may be dirty and/or sticking. Otherwise the scan sensor is going out.
To check and clean the the shading compensation strips:

Open the feeder up all the way and hold down the red stop button. about 5 seconds the upper and lower shading compensation strips will pop up.

They may be getting stuck and not popping out all the way (about 1/2")
Clean them up with a small brush and a lint free rag with alcohol.

If the shading sensor strips aren't popping out all the way, this will cause the problem you described, so clean them up and repeat this several times.
(They pop up during the document scanning process)
If they still aren't popping out after cleaning them up, then there may be a mechanical problem with the mechanism.

Hope this helps! You may need a tech.

You need to change the mylar strip on the ADF and also you need to clean the narrow strip of glass that the scanner uses for ADF scans. The Mylar strip is found by opening the lid, as you do when you put a document on the glass. On the left side you will see a Mylar sheet that covers a white backing section. There is a latch on the front and back of the Mylar mount that allows it to drop down. There should be spare Mylars in an envelope tucked under right edge of the white backing strip for documents placed on the glass. Just be sure to orient the new strip the same as the old one. The mylar strips can sometimes be cleaned but usually it is better to replace it if you have spares.

Allow 3/8 inches (1 cm) or more space between the edges of the platen glass and the document.
Align a corner of the document with the corner at the arrow of the platen.

Black line through the middle of the document

The thick line is either because of dust sticking to the glass or a module problem. Try different brightness settings and scan white paper. If the thickness varies and also the sides of the black strip are jaggered (step like) then it is dust on Glass. use isopropyl alcohol to clean, dont use solvents. If the teickness is same for all levels of brightness and has a sharp edge always, it could be scan module problem.

check on the flat bed part along the top. there are two white strips that go side to side. the top white strip is wider than the bottom strip right underneath it. On the thinner of the two strips, check for small black marks, can be very small. This creates a black line in the document. You can clean it with a fingernail & a tissue

Dark strip down center of page when coping from tray

There is a small strip of glass on the left side directly under the edge of the scanner, About a half an inch wide. It has something on it.
May be very hard to see, use a strong glass cleaner or some alcohol and a regular piece of paper to clean it with.

Black Line

Take glass cleaner and clean the small strip of glass to the far right. If there is a speck on that strip of glass it will cause a line when it scans.
