black vertical line when using the feeder on my HP 6500 E709n

Is there a trick to rotating the ADF mechanism? It only raises an inch and doesn't rotate the full 90 degress as shown in the instructions.

I might be able to squeeze a rag into the small opening in an attempt to clean the feeder glass but it would be much better to open the ADF all the way.

The mechanism does not retract back, as you say, but does give a small gap. I took some soft cloth (normally used to clean a lens), fixed it to a ruler, doused it with glass cleaner, and was able to polish the glass through the gap ...and it worked, after the second cleaning. Now, a few days later, the print outs are either blank or with faint and scratchy black type, but I do not think this was a consequence of my cleaning the glass

I managed to partially detach the ADF enough so I could get to the feeder glass.

To do this, locate the hinge hole (front side of printer) and pull the plastic holder away (towards you) so the hinge pops out of the hole. That releases the ADF and while it doesn't really rotate back, it lifts up enough to get access the feeder glass.

I had the same problem (single pixel-width black, vertical line using document feeder) and by spraying out the feeder with compressed air ("cleaning duster" bottles sold at Office Depot, etc.), I didn't even have to open it up.  Very useful to have compressed air to get dust off the feeder, glass, and photos.

Read the document attached and referenced earlier in this thread, in the 6500 the adf DOES lift- it however deliberatly a stiff hinge.

Also use an eyeglasses microfibre cloth wrapped around a chopstick to wipe the glass, if marks persistent - then try again, concetrate efforts on the section of glass where the streak lines up with.

Causes: Dist, gum from previously scanned documents or worse a scratch (non-fixable) this is why scanning with staples clips etc still attached to documents is a big NO NO

This thread and the attached documents helped me - the chopstick is my own invention 🙂

Good advice on here earlier.  The glass window that collects debris is not easily accessed - not sure why.  The key is a firm but gentle touch on the referenced plastic bracket.  Locating the bracket?  On my machine (assuming this is typical) there is a white sticker with a bar code on this plastic piece.  At the right-hand side of the bracket, you'll see a U-shaped notch feature that the ADF itself rests in.  On the left-hand side of the bracket, you'll see two holes in the bracket:  one hole serves as the seat for a hollow plastic post on the ADF that works as a hinge pin when you lift the ADF. (it only lifts around 3/4 inch before this bracket restricts rotation).  To gain access to the glass, pull/flex the plastic bracket carefully - finger pressure is adequate as a screwdriver may be too harsh - toward you (toward the front of the printer).  I believe a heavy hand here would snap that puppy clean off, so be careful.  While you flex it forward, rotate the ADF upward - eventually you'll gain clearance for the ADF to come up out of the bracket.  It will remain in the printer, so don't think that it comes all the way out of the machine.  I MacGyvered a little cleaning pad out of a piece cut off a Swiffer (floor cleaner) pad wrapped around a wooden stick - if I had  an eyeglasses cleaning cloth and chopstick as suggested earlier I would have used that instead.  The point is to use something that won't leave debris.  I blew it clean with canned air.  Replacing the ADF into the bracket is pretty easy as it snaps back in place.  I've cleaned mine twice in the past 3 months, both with immediate relief.  I'm hoping that I haven't fatigued the plastic to a point wher it weakens and breaks.

I don't know what you mean by "bb" -- the size of the line is narrow, not thick -- and only one.  HP's directions for getting into your model's ADF are good.  I've tried EVERYthing they suggest and nothing has work to eliminate the line while using the ADF.  So I scan on the flatbed only when it really matters.

Awesome!  Wish I'd checked sooner. This last test scan looks like it came from a brand new machine!

Hi all - I just cleaned the small feeder glass as recommended and found a tiny little bit of dirt on it, gave it a good clean and now completely fixed!

I really enjoy using my hp7250 however I get a black vertical line when I use the feeder instead of laying documents on the glass

please help
