HP LaserJet 2840 Scanner problem

I have no idea what "paperport 11" is.
That being said, normally a line down the page when copying or scanning is caused by dirt on the Automatic Document Feeder glass, Not the flatbed glass. It is a thin strip of glass to the left of the flatbed scanner glass. Clean it.

hi
Place the document or image into the scanner for scanning. A scanner with a paper feeder will only receive flat papers and photographs, but a flatbed scanner opens to accommodate books, fabrics and leaves along with flat papers. There is even a attachment for feeding photo slides into flatbed scanners.

Step 2 Start the scanning software. If the scanner does not engage the software automatically, press the "start" or "scan" button, or click the scanner icon on the computer screen to initialize the software.

Step 3 Activate the scan. Click the "file" menu and select "acquire," "import," or another practical choice that applies.

Step 4 Preview the item to be scanned. Most scanners have a preview option. This will show the scan area inside dotted lines. The lines can be moved with the mouse to relocate, enlarge or crop the scanning area.

Step 5 Set the resolution for images by number of dots per inch (dpi). For computer screen viewing, 100 dpi should suffice. Use 200 to 300 dpi for items to be printed.

Step 6 Use the appropriate setting for scanning black and white text. If the scanner does not show a preset for text, use "line art" or "black and white" at 300 dpi. Then use the optical character recognition (OCR) program to convert the image of the text into a file for word processi

On the scanner glass it will scan only one page. If you want to do multiple pages. you need to use the ADF
Automatic document feeder.

Check the feeder, it is either loose or broken making the printer to think that you have in a different size or type of document.

Based on the assumption it's mechanically ok, check the cable connection between the document feeder and the base, if damaged or worked look it can cause errors. If it is a sensor error, check for a small bit of paper or even a staple from a prior jam.

If you are receiving an Error Code 103 or a Paper Jam error, but there are no pages in the ADF (Automatic Document Feeder), follow the steps below:

1. Close the scanning application (such as PaperPort)
2. Turn off the scanner and the computer
3. If you have a combination ADF with a Flatbed scanner, unplug the ADF cable from the base of the scanner
4. Plug the ADF cable back in
5. Turn on the scanner power
6. Turn on the computer
7. Try scanning again

For a Paper Jam or Error Code 103, make sure that the ADF cable in the rear is connected to the scanner base. Check the flatbed to make sure that it is clear. A page incorrectly placed on the flatbed may interfere with a page feeding through the ADF.

If your scanner stops scanning due to a paper jam in the Automatic Document Feeder (ADF), a warning dialog box appears after a few moments.

To clear a paper jam:

1. Open the Automatic Document Feeder cover.
2. Remove the jammed paper and close the cover.

If you are receiving a paper jam error, or if the scanner is running continuously, check to make sure the paper sensor arm is not stuck down.

1. Open the Automatic Document Feeder cover.
2. Look for the small black plastic arm
3. When you press on this arm, it should move freely up and down
4. If the arm is stuck down, please contact Technical Support for troubleshooting options
5. Close the ADF cover.

have you downloaded the scanfix that is own the HP support site?

You would face the taxt or images face up then you would scan it by using the program it came with if it did or any othere program the can scan documents and imagees on you computer. Make shure all conecsions are conect property and the software is installed.

Document feeder error means that the printer is expecting you to have a document in the ADF "automatic Document Feeder" on top. If you are having this on the laptop, go into the scanner set up on your laptop, and change the device from document feeder to flatbed. It should work fine. You can also mimic the settings from your desktop to your laptop.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Loading originals to scan
Use these instructions to load originals into your device for scanning. For the best quality
scans, use the flatbed scanner. See Selecting media for the automatic document feeder
(ADF) for guidelines on choosing original documents for scanning.
Loading originals onto the flatbed scanner
1. Make sure that the automatic document feeder (ADF) input tray is free of media.
2. Lift the flatbed scanner lid.
3. Place the original document face-down on the flatbed scanner with the top, left corner of
the document at the lower-right corner of the glass.
4. Gently close the lid.
5. The document is ready to be scanned.
CAUTION To prevent damaging the device, do not allow the scanner lid to fall onto the flatbed scanner
surface. Always close the scanner lid when the device is not in use.
Loading originals into the automatic document feeder (ADF)
input tray
Note The ADF capacity is up to 50 sheets of 75 g/m2 (20 lb) media (depending on the thickness of
the media), or fewer sheets if the stack fills the ADF.
The minimum size for media in the ADF is 127 by 127 mm (5 by 5 inches). For smaller sizes
use the flatbed scanner. The maximum size for media in the ADF is 215.9 by 381 mm (8.5 by
15 inches).
1. Make sure that the flatbed scanner contains no media.
2. Close the flatbed scanner cover and put the top end of the stack of originals into the ADF
input tray, with the media stack face-up and the first page to be scanned on top of the
stack.
3. Slide the stack into the ADF input tray until it does not move any farther.
