One or both of the ADF hinges are bad. The ADF cover doesn't close all of the way causing feed failure of the original and shading on the side of the copy because the scanned original is not fully contacting the **** exposure glass on the front operators side.

Re: top feeder not working MF6550
OK first Les Welder is a nut, thats crazy NO HAMMERED REQUIRED. First you'll need to call an independent Canon Copier Dealer. Tell him that he should to replace the paper feed tires in the ADF assembly- Your tires are worn and should be replaced, I am taking it that it works but won't feed ? Correct ?
Second the black lines - this could be coming from : A.) The Toner Ctg B: The Class- like white out-A Copier worst enemy C.) The Charge Roller- especailly if the images are dirty D.) Dirty Laser Unit- internal mirrors.

I am going to assume you are using the Auto Document Feeder for when you are copying and faxing.
When you lift the scanner top (As if you are placing a single document on the scanner glass) there is a small strip of glass to the left (normally) of the main scanner glass. This is the ADF scanner location. You will find that there will be two marks on this glass at the points you get lines on copied and faxed documents. Normally this is ballpoint ink that was not completely dried when fed through the ADF or Twink (Whiteout) that was not completely dry when fed through the ADF. Using rubbing alcohol or other cleaning products of similar gender clean this mess off the glass. If it does not come off it could be actual scratches on the glass which can only be fixed by replacing the glass.
The rollers on the feeder can go bad and the best way to solve it is to get a new complete assembly. Check the website under your make and model for the assembly. YOu might also want to check for paper jam
This black line sounds like it is definately coming from the ADF scanner glass. This is the thinner strip of glass that is located just to the left of the large original glass. You can verify this by making a copy from the large glass instead of using the feeder on top. If the copy comes out clean then it is definately the scanner glass. Just clean the glass well with glass cleaner and a soft cloth. This glass is only used when copying/scanning using the top automatic feeder
Good Luck and Thank You for using Fixya.
A dark line on printed pages that are printed directly from the computer are most likely coming from the Drum Unit.
A dark line seen after making a COPY of a document using the feeder on top, is caused by a dirty scanner glass.
In the first example the fix is to replace the drum unit.
In the 2nd example you need to clean the scanner glass. The glass can be seen by lifting up the automatic feeder on top of the machine and exposing the large original glass. The document feeder glass is the smaller thin strip of glass that is located just to the left of the large glass. Clean this strip well with a cloth/paper towel and a bit of glass cleaner.
Good Luck and Thbak You for using Fixya.
Yes - surprisingly - we had the same problem, the gray stripe along the side of the page only showed up when the original was fed through the document feeder on top. Cleaned the small area of glass under the feeder repeatedly with no change to the resulting stripe, but then while cleaning the upper roller, above the area of glass where the scan lamp illuminates during the copying from the ADF, we found a small piece of paper adhering to the top roller in the paper path, cleaned it off, and no more band. We didn't see the bit of paper on the upper roller until we rolled it while cleaning. Still can't figure how that made a stripe....but hope this helps you.
You may have selected to fax from glass or you may have a piece of paper on the glass.
If your placing the paper in the document feeder and it is still not rolling in. Check to see that there isn't anything jamming the feeder. The thing that activates the feeder and tells the printer to fax or scan from feeder is a small spring latch that sits internally at the top part of the cover and when ever paper is fed through it, it will engage the feeder. This small spring latch can easily come off or disengage from the unit especially if you have recently moved the printer. Check to see if it's a spring problem. If it is all you have to do is place it in place and all should work as normal. Be very careful not to force anything and gentle with any other component that you may encounter while looking, they can easily brake off.
Hope this works for you!
