JP J5780 Streaks in the rollers and ink

I purchased this printer six months ago. I am having two issues with this all in one.

1. The scan feeder scans two streaks from the top to the bottom of the page. I have asked and looked around for something to clean the rollers but have had no luck.

2. When I print documents, the letters do not come out. The printer settings are set to normal. It will print only the top of half of the words in all sentences.

Please help me. I really dont want to waste a printer.

Why are pages scanning with lines running through them, but printing perfectly fine?


Try cleaning the rollers. Usually you have to remove the cartridge to get to the rollers that moves the paper.

Scanner leaving black streaks


There are two possible fixes.

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

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.

HP OfficeJet J5780 Vertical Black Line Prints when copying or scaning only. Cleaned rollers and changed black ink cartrigde. Still problem.


Have you tried cleaning the document feeders Scan Glass? (small glass under doc feeder ~ 1" by 9") Most times there is dirt spot on this glass, causing a shadow on scans and copies.
Try copying from the large glass by lifting doc feeder / platen cover and manually placing original. If no line copying or scanning manually from large glass, then small scan glass is deffenitely the culprit. Hope this helps.

Red/yellow line down left side of document when using feeder


the solution to this issue is cleaning the scanner glass below the automatic document feeder(mind you its not the scan bed that you normally use while copying) .you will get the ADF scnner glass once you lift the ADF door,you will see a 1 inch wide scanner glass.that is what you need to clean.

HP Officejet J5780 All-in-one Injet prints a grey line down the right side of the page when copying using the automatic document feeder. It does not show up when printing; and it does not show up when...


lift the feed area and look at the small glass plate where the auto feed paper is actually scanned. That needs a good cleaning. Since the paper runs across it even a tiny little obstruction such as paper left from a paper jam or a dot of ink from that pen you used to unstick that last paper jam (maybe its just me??). That one dot turns into a line when the paper rolls across it. Clean well and the line will dissappear.

Black lines when scan and copy documents


It is because coping is not the best way to get a perfect copy on the printer, Try scanning with computer using black and white photo it will come out much better if you are doing a pic. then use color picture.
