Vertical line down the scanned image

T'Con board fault. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.

If that is the last page that has the streak use a blank page in the original scan as the last page and then the dark line wont cover the image.

Probably there is nothing wrong with that scanner, just open and clean document feder with alcohol or glass cleaner.

There are two possible fixes.

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

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.

Other Possibilities


If... Then... Vertical lines appear only when printing... Consider other printer-related topics such as toner cartridge, charge roll, photoconductor, transfer roll, or fuser. Contact Lexmark Technical Support. Vertical lines appear when you lay the page on the flatbed...

Make sure all the scanning settings are correct first then set everything first before you preview image then hit scan.
make sure the size is correct drag the image on the prview screen make ths dotted lines frame your image then scan
remember you tell the machine what to do by setting it, if you dont the machine trys to do thevscan its self. Good luck, have fun

This is because of dust sticking to the glass. Clean with isopropyl alcohol (rubbing alcohol) and dont use solvents. For emergency you can use your after shave but take care only to clean the glass portion!

There is something on your scanner glass. Clean the glass with glass cleaner. If this happens when using the automatic document feeder, open the top side cover where the paper feeds into. There is a narrow glass strip there. Clean that as well.

If this fails, the scanner head has a bad sector on the CCD and will need to be replaced. You will probably find that it will be cheaper to replace the printer entirely if that is the case.

I just need to understand the exact issue. It sounds like you are able to successfully scan, see the preview of the scanned image, and you initially save it. Then, when you go to open the saved image, you don't see the image you scanned but rather a "line". You've saved the image in a number of different image formats, but there's no difference in the result. It saves the scanned image to the location you want to save it on your computer's hard drive (probably My Pictures if you're using a Windows operating system).

Not sure what you mean by a "line". Do you mean a vertical line, a horizontal line, a diagonal line or what? Also, is it just a solid black line on a white background? Is it the image you scanned compressed into a smaller vertical or horizontal space?

Have to tried scanning both text pages and graphic pages? There have been issues where a document with both text and pictures has been scanned but when the scanned image is viewed, only the text appears. The pictures don't make it. The description of this specific problem is at HP.com.

I take it you don't get any sort of error message associated with this problem. Unfortunately, I can't find your specific problem at HP.com beyond the link I posted in the above paragraph. If you can answer some of the questions I asked, it might help me provide a better solution.

Thanks.

Did you try cleaning the little glass strip where the documents go in? Lift the button panel and wipe the glass with rubbing alcohol and cotton swabs or lens paper if you have it. Mine does this sometimes when dust or white out or little bits of paper get stuck on the glass.
Good luck!

You should clean the small glass under the top lid. Chances are there is some white out or ink or mark on the glass. Look carefully because usually it is just a small dot>
