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

Scanner leaving black streaks


There are two possible fixes.

Download the latest firmware update by CLICKING HERE

The following is provided by courtesy of Lexmark:
Problem Vertical lines; Auto document feeder scan anomaly; ADF scanning problem; Scan issue; Scanner issue; Visible line; Streaks show on page; solid line down the page; Top to bottom line; Smudge runs down the page; Opaque line; Broken line; Bar all the way down the page Solution Overview

This article provides the self-diagnostic steps necessary to evaluate top-to-bottom streaks that appear when copying or scanning.

Important! This is seldom a scanner hardware failure.

The main reason for this anomaly is debris or marks on the scanner glass that is used for Auto document feeder (ADF) page scans.

Printed or Scanned Page Illustration

copyvertstreaks.jpg

Who should consider this article?

Any user of an MFP or All-In-One printer experiencing the following symptoms:

  • -Vertical lines only when using the Autodocument Feeder (ADF).
  • -Observed with any type of scan job (e-mail, ftp, solutions, fax).
  • -However, normal expected output when the page is scanned from the scanner flatbed.



ADF scan behavior

Think of it this way:

  • -The page is pulled from the ADF.
  • -The moving page slides across an ADF-designated portion of glass.
  • -The image sensor, which is located under the glass, reads and interprets the moving page's contents.
  • -Contamination on this ADF glass is seen by the image sensor for the entire length of the page.
  • -The image processor interprets the image sensor's repeated capture of this contamination as a vertical solid line.
  • -Any ADF scan function now exhibits a vertical line.

Suggested Diagnosis and Fix




Step Action 1 Locate the portion of the glass designated for ADF scans.
HINT: The glass location differs by model. This area is often separate from the scanner flatbed. Please reference User's Guide for more information if you are having a difficult time locating this designated area.
2 Perform a visual inspection for any of the following recurring culprits:

  • -Clear adhesive tape
  • -Glue
  • -Ink pen
  • -Paper
  • -Marker
  • -White out
  • -Staples
  • -Environmental dust or dirt
HINT: Ink marks can be especially hard to see and almost translucent at first sight. However, the image sensor (CCD) registers them as a mark. 3 Use a clean, soft, moistened cloth to thoroughly clean and remove any marks or debris. 4 Inspect the underbelly or underside of the ADF for any marks or debris. 5 Perform another scan to see if cleaning the glass alleviated the issue. 6 Repeat the procedure if a vertical line still appears.
Remember! Printing and scanning from the scanner flatbed work fine.
7 This time, place an intentional mark on a blank sheet of paper and take note of its location. Now place that sheet of paper in the ADF and make a copy.
8 Evaluate the distance of the vertical line to the your mark. 9 Inspect that area of the glass for further debris or marks and clean as necessary.

Open the scanner cover and you will see two glasses. One long and thin and the other larger than an A4 sheet of paper. The long thin glass is used to scan thru the adf and the larger glass is for flatbed scanning.
As your lines are from the adf scanning, you will see tippex on the long thin glass. just clean it off and all will be well. Clean the flatbed glass as well while you are doing the job on the adf glass.

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

Copy off glass copy is good. copy from ADF copy is blurry


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.

Black line in paper


On what operation are you receiving the black line in your paper?

This problem usually appears when you try to scan or copy using your ADF (automatic document feeder).
To remove this black line in your paper, clean the ADF platen glass in your printer and do as well in the flatbed scanner glass. This ADF platen glass can be found right below where the documents in the ADF goes through. Its a glass about 1 inch in with and beside the flatbed scanner glass (the one where your documents is lay down for copying and scanning. Dried ink or paper residue sticked in the glass can cause this line in the paper. Clean it with a a clothe and spray some windex on it.

Good luck!

When using the ADF to scan multiple document the scanner assembly stay stationary and the paper is fed across it. Where the scanner parks for this there is something between the scanner and the document, likely on the glass. Often there is a small strip of glass on one end of the scanner bed. Clean here if there is one, otherwise look around and I'm sure you'll find it. Remember, never spray cleaning solutions directly onto the glass, always onto a cloth or towel first. The scanner has a calibration strip that can be damaged otherwise.

How do I scan more than one page at a time


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.

Paper jams when using the ADF. Canon IC D780


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.

When making copies using the ADF, vertical lines print out on the paper. Doesn't happen when paper put directly on the glass.


The ADF works by moving the paper past the scanhead, on glass works by moving scanhead past the paper.

When you are scanning with ADF, the scanhead is parked in a particular position, under the glass. Just at one extreme end. Open the unit to te point that you are able to clean the lint, debris, lollipop sticks from this area. That should be it, since works otherwise indicates a good scan head.

Will not copy


If the paper isn't feeding in the ADF (automatic document feeder - upper paper feeder) then the ADF roller assembly will need to be replaced. Try a copy on the flat glass area. If it work, then it's the ADF, If not then the upper scanner assembly with have to be replaced.
