HP Laserjet M1522NF MFP Scanner adf

Hi Bridgette.

The red light on the startup-button indicates that the machine is not ready for a photocopy. Usally there is something stuck in automated document feeder (ADF). Take a close look and see if can see something in the paperpath. If no luck, try pushing a A4 sheet manually through the ADF and see if something comes out with the sheet. Usally there is a small piece of paper, a paper clip or a staple stuck in the ADF. If nothing found in the ADF, the Scanner Controller Board is probably broke, and needs to be replaced. Good luck.

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.

There are two possible fixes.

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.

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... Consider other printer-related topics such as toner cartridge, charge roll, photoconductor, transfer roll, or fuser. Contact Lexmark Technical Support. Vertical lines appear on ADF-fed printed copies, but they do not appear on scan-to-network [e-mail, FTP, folder (PC), solutions]... Consider other printer-related topics such as toner cartridge, charge roll, photoconductor, transfer roll, or fuser. Contact Lexmark Technical Support.

Hi,
I think that ADF of the printer is causing the issue and requires cleaning. Fortunately, HP Official support has provided the details along with pictures about maintenance/ cleaning of the ADF Unit.
Cleaning the ADF delivery system
Please visit the above link and follow the procedure to perform regular maintenance of the copier.


Hope it helps! Good Luck! Thanks for using Fixya!

Open adf cover, remove adf pick up unit, two sensor located in it 1. paper leading edge sensor, located upper portion of the unit.2. paper out sensor located back side of the adf pick up unit. Carefully open this unit your will easily find out the sensor location..

Do the calibration for the scanner.

1. Place letter- or A4-size paper in tray 1, and adjust the side guides.
2. On the control-panel Home screen, scroll to and touch Administration.
3. Touch Troubleshooting.
4. Touch Calibrate Scanner.
5. Touch Calibrate to print the first pass of the calibration target(Print out).
6. Place the first pass of the calibration target face-down in tray 1 so that the arrows are facing into the MFP.
7. Touch Start to print the second pass.
8. Place the calibration target face-up into the ADF, and adjust the side guides.
9. After the calibration target has passed through the ADF once, reposition it face down in the ADF and touch Start.
10. Place the calibration target face-down on the scanner glass, touch Start, and scan the page.
After this pass, the calibration is complete.
Calibration will fails if print quality is not good...ensure that print quality must be in order..
Once calibration successfully done, restart printer several times & verify start button light, if its green every time 'u' re success. if not cleaning required for CCD which is major work & not suggestable..

Most likely dirt on the glass for the ADF scanner, but try making a copy from the glass first by lifting the lid and placing the document directly on the scanner. If that is clear, then it is definitely dirt on ADF glass. The ADF glass is the smaller piece of glass you see when you lift the lid. Use window cleaner and a soft cloth to make sure that you have all traces of dirt, liquid paper, post it note glue. Look at the glass from very carefully because even the slightest bit of goop can cause scan defects.

Make a copy from the glass NOT using the feeder. Does the line go away? If so then you have something on your adf scanner glass. If the line is still there when copying from the glass it pretty much has to be coming from the toner cartridge. If so then try changing cartridges.

There are some small spots on the "seal" glass. It is the 3/4 inch wide strip under the scanner, not the main glass. Clean that strip well, I suggest taking some rubbing alcohol and just a regular piece of paper, crumpled up. Use that to clean that strip vigorously.
That will take care of it.

Dirt.
Open the ADF, the top of the scanner/copier.
The ADF glass is the thin strip of glass on the left. Damp cloth with windex or any glass cleaner. Scrub the strip of glass.
