SOURCE: Brother DCP8020D Document Feeder

Clean rubber rollers with metho, run a page by hand of laminate or stiff card threw the doc feeder. Stick it where the paper comes out of DF and ensure path is clear.

Push down on left side or tape down little black switch (rear left corner near glass)while trying to use df to confirm hinge aint the issue

If it is the rollers it should feed when paper is "helped a little" with hand at feed time

Ensure prints ok when using glass instead of df to know it is df problem

Cheers

SOURCE: Document Feeder jams

I got adventurous and removed the screws holding the document feeder. I then used a can of air and blew into the gears and then reassembled the feeder. It works perfectly.

SOURCE: automatic document feeder not working

Open the adf and rotate the pick assembly till you hear a click and then take a coin and run it up and down against the separator pad and then see if the adf picks the paper or not.If this does not work try this *# 329 and scroll thru and select adf pick test if that fails its time for you to get the printer replaced or get an upgraded printer

SOURCE: Need to replace pickup roller on MFC-7820n.

Well, how to do that I don't know how to explain you, but first of all try to clean it, do it with thinner, this may solve your problem for while, at least until you find a way to remove and change.

Need replacement process for paper feed roller in scanner compartment.


On the doc feeder there are 2 arms that go down into the machine. UNPLUG machine first. You squeeze them carefully and rock the doc feeder backward. It may take some manuevering,

Once you have separated the top half of doc feeder, you will see a wire harness going into the upper half, CAREFULLY unplug it. There are several screws holding down the cover over the bottom half, remove them and again carefully separate this cover from the main body.

Once this is done you should be able to replace the feed roller. One note, while you have it this far apart you ought to change the separaetor pad in the top half.

My fax is having a problem feeding pages through the document feeder, it doesn't always grad the page, and if it doesn't get it, it acts like it has a paper jam, what is causing this?


Open the document feeder. Inside you will find a grey feed roller. Cleaning this roller with a cloth dampened with water will help with these paper jams in the document feeder.

Doc Feed Problem


I would replace the Pick-up roller, Feed Belt, Sepearation roller, and torx Limiter for starters IF you cannot replace them, Clean them with warm water and soap, let them dry, and try the doc feeder, Most Multi feed problems are Torx limiter or clutch problems.

Need more info. Do you need help in replacing the roller? If so, it is a big job. You have to completely remove the doc feed asm and all covers to get to the roller shaft asm. Best to let a tech do it for you.
Have you tried cleaning it with some roller cleaner. Try a little bit of Goof-Off cleaner on a cotton rag.

Xerox WorkCentre XD105f auto doc feed fails. The roller does not descend far enough to contact the page being fed


There is a spring wound clutch that is slipping in the doc feeder.
You can try cleaning it or google a place called The Parts Drop.
Call and ask for Britt he can help you with ordering the right part at a fair price.
