I fixed this by changing the Copy Intensity from Auto to Manual
I had the same paper jam (caused by pressing Stop during a page going into the ADF), but I had pressed OK as instructed and the page was auto fed back out again. Then I couldnt copy from ADF after that.
I tried everything, and then started to retrace my steps of all the things I might have tinkered with to try and get the copying working in the first place, before the paper jam.
Then I remembered I had set the Copy Intensity from Manual to Auto (thinking Auto is always best). With hindsight, it now makes sense for it to be manual with the ADF as otherwise how would it load a page, use it to set auto density, and then reload it again for the actual copy to occur. This happens okay on the flatbed scanner as it can scan a little, work out the settings, and then scan for real.
Copy Intensity is reached on my Canon MX from the Menu button at the bottom left of the front panel. - Then press the right arrow twice to get to Color Intensity. - Hit OK. - Then right arrow from "Auto" to "Manual Adjust"- Then pick a setting or leave it as half-way between light and dark- Press OK
Now every time my ADF copying works a treat. Thats what I get for tinkering in things I didn't need to change in the first place. I was just trying to get a quick copy going from ADF to paper without saving a file up on the computer and then printing.

1 Load the document in the ADF.
2 Press [COPY].
3 Use the numeric buttons to enter the number of copies. (up to 99)
4 Adjust any necessary settings for your document.
5 Press [Start].
NOTE
To cancel copying, press [Stop/Reset].

You can load up to 30 sheets of plain paper in the Artisan 800 ADF. If the ADF doesn't feed the paper, check the following.

1. Make sure that you are loading plain paper only without a holes. 3-hole punched paper is not supported by this printer.

2. Load paper not exceed 30 sheets.

3. Open the ADF and check for any jammed paper or foreign object that is blocking the paper feeding path.

4. Check if the BIG GREEN ADF indicator is lit when you load paper in the ADF.

If the issue persists, your printer will require service. You can contact the Epson for warranty if your printer still under warranty. If your warranty expires, look for an a service center that can repair your printer.

YOur problem is likely worn feed rubber. It is an old machine. Has it ever been serviced?
Did this happen after a paper jam?
Try this: UNPLUG the copier Take out the paper tray. Prepare a dry cloth that is dampened with WD 40. Open the door on the right side of the coper. You should see 1 large, gray or black rubber roller. Gently wipe the roller with the WD 40 cloth, slowly turning the roller. It only turns 1 way, towards the exit direction of the paper from the copier.

Let the WD 40 soak in, about 10 minutes. Put the paper tray back in, plug the copier back in and try to make a copy. If it makes a copy, the feed roller needs replaced, If it doesn't make a copy, check the top sheet of paper in the tray. If you see skid marks, you definitely need a feed roller. No, they are not easy to change.

As long as the roller feeds, go for it. When it starts slipping then you'll have to do something about that feed roller.

Hi there,

When using ADF
Note:
* Set a document on the Platen Glass if you want to scan it at optimum quality,
* The area (range) within 0.08"/2mm from the top edge if document cannot be printed since the machine cannot scan it.
*Do not load the following types of documents in the ADF. They will jam.
-Wrinkled or creased paper
- Curled paper
- Torn paper
- Paper with holes
- Carbon paper or carbon-backed paper
- Surface treated paper
- Onion skin or thin paper
- Photogragh or thick paper.
1) Remove any documents from the PLaten Glass.
2) Open the Document Tray.
3) Load the document in the ADF.
Load the document with the side you want to copy, or scan face up in the ADF.
4) Adjust the Doument Guides to match the document width.
Note :
Ensure that the edge of the document stack is in line with the Paper Size Mark imprinted on the Document Tray.

Hope this helps.
Please rate my response.
Thanks
Have a good day.

Anita,

Put the pages in the "multiscan" all at once, not just one sheet at a time. The Automatic Document Feeder (ADF) will feed one sheet of your document at a time untill all of the pages are scanned...
Thanks for using FixYa!

not really familiar with this model, however, you should be able to open the cover (slightly) where the paper feeds in and you will see some rubber rollers (likely top and bottom), try cleaning these with a rag dampened with some alcohol (preferably), or water, and turning gently (do not force). If you use water, dry them afterward

the ADF is the automatic document feeder the part on top of the machine that you insert the paper to Automatically feed the paper in one at a time, there may already be a document on the glass lift the top and put it back down it should clear

has the feeder attempted to feed in the document ? Check to see if there is already a document on the copyboard platen
