Adf scan problem

Try checking for debris or other on the ADF itself and below on the prism. The ADF cover glass could be spotless, but if there is a speck on the prism itself, this could cause the actual prism to send a line while scanning.

HP ScanJet 4p Scanners - How to Use the Automatic Document Feeder (ADF)
Tips for Using Step 1 - Load the Paper Step 2 - Scan the Document To Scan a Single Page Tips for Using

• Remove any paper from the copyboard glass before using the ADF.
• Straighten any curls or wrinkles from documents before putting them on the document tray. If this is not possible, do not scan these documents using the ADF. Instead, use the copyboard glass or make a photocopy of the documents and scan the photocopies.
• Remove staples, paper clips, and any other materials from documents.
• Avoid documents with tears, perforations, or punch holes.
• Do not use the ADF to scan sheets of uncommon paper or other media, such as the following: - transparencies - gummed-backed paper - magazine pages - lightweight ("onionskin") carbons
• For paper smaller than 5 inches (127 mm) by 7 inches (178 mm) or larger than 14 inches (356 mm) by 8.5 inches (216 mm), use the scanner glass instead of the ADF. Paper smaller than the minimum size may cause a paper jam.
• For paper lighter than 16 lb bond (60 g/m sq) or heavier than 32 lb bond (120 g/m sq), use the scanner glass instead of the ADF.
• Before scanning, always push the front of the ADF downward to the scanner to ensure that the magnetic latches are engaged.

Step 1 - Load the Paper Besides the instructions below, quick reference decals on the input tray and access hatch show the order of steps for paper loading.

1. Turn on the scanner.
2. Ensure the scanner's scanner glass is free of paper.
3. Turn the green paper load lever into an upright and open position. Refer to decal number 1 located on the ADF access hatch.
4. Put the top end of the paper stack face up on the input tray. Refer to decal number 2 and pointer arrows on the ADF input tray.
5. Push the paper stack up against the green document guide and slide it right against the green registration stop, which is in the middle of the paper load window.
6. Turn the green paper load lever 45 degrees into the closed position. This will secure the paper stack. Refer to decal number 3 on the ADF access hatch. The ADF is now loaded and ready for scanning.

Step 2 - Scan the Document The ADF works with many software packages that are compatible with the HP ScanJet color scanners. To scan a document, refer to the user's manual of the software package being used. To Scan a Single Page To scan a single page while the ADF is installed on the scanner, do the following.

1. Remove any pages from the ADF input tray.
2. Raise the ADF.
3. Place the page on the scanner's copyboard glass.
4. Lower the ADF all the way and do the scan.

The problem is either dirty glass for the ADF which you can clean, or the ADF cannot feed the paper you are trying to scan through accurately. Most smaller all in one printers use the same scanner element for both the ADF and flat glass scanning so the fact that glass scanning is fine points to the two problems listed above.

Hi there,
To scan more than one page at a time you can use ADF.
The Automatic Document Feeder (ADF) can scan multiple pages, including duplex pages. When using the ADF:
* Load the document into the ADF faceup, short edge first.
* Load up to 50 sheets of plain paper into the ADF input tray.
*Scan sizes from 148 x 210 mm (5.8 x 8.3 in.) to 215.9 to 355.6mm (8.5 x 14 in.).
* Scan documents with mixed page sizes (letter and legal).
*Scan media weights from 52 to 120 g/m2 (14 to 32 lb ).
* Do not load post cards, photos, small items, transparency, photo paper or the thin media (such as magazine clippings) into the ADF. Place these items on the scanner glass.

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

when you try to scan through the adf part a message is displayed on the screen. Something like "Document loaded". Otherwise it's scanning the glass part. Maybe the sensor in adf part is bad, not responding

See the item is placed correctly on the scanner glass or in the ADF.Make sure that the item you are trying to scan is placed face down onthe glass, or face up in the ADF. Ifyou are using the ADF, there might be a page on the scanner glass.Raise the ADF unit and remove any pages on the scanner glass. If you are using the ADF, the ADF window might need to be replaced.

If that is okay, Please check this link.

Have you tried lowering the resolution of the scanned document?

Put the paper in the automatic feeder. In the software options, click on ADF (automatic document feeder) and it will scan multiple pages.

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.

I need a little more description. Does the ADF handles the first page, or no page at all? Keep in mind that Samsung designs its own scanning application (SmartThru). Also check that the connection (parallel or USB) is correctly configured on your app.
