Two black vertical lines appear on copy, pdf, and scan results

Today - the first time - when I copy or scan, two equidistant vertical lines appear on the resulting paper. The printer prints just fine - no vertical lines. Just copy and scan.

Black line on copies


Check the drum history? If the yield is not yet reached, you should clean the charge roller, cleaning blade brush and cleaning blade. Remember to vacuum beneath the cleaning blade! See if that works, otherwise you should call a techie to replace the drum. If yield is not reached they will charge you for a new drum.

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

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.

4215 all in one office yet. When making a copy


Sounds like you're having a problem with the automatic document feeder. The scanner is continuing to scan but the paper is not advancing as it should during the first part of the infeed. Check to see if something is inside retarding the path of the scanned document. Or it could be worn rollers in the ADF.

Black vertical lines on copies and scans from auto


This means the read area is dirty. Clean the glass with glass or lens cleaner at the area where you place the head of the paper if you wanted to lift the cover and scan a page without the autofeeder. There may be white out or toner stuck to the glass. This can be removed with a glass blade.
This answer assumes that prints from the computer are fine...

New cartridges - printer not printing


Align your cartridges to solve print quality problems such as: • Characters are not properly formed or are not aligned at the left margin. • Vertical, straight lines are wavy. 1 Load paper in the paper support. 2 On the control panel, press Copy. 3 Press Options until Maintenance appears. 4 Press the right arrow until Align Cartridges appears, and then press Select. An alignment page prints. Once this page prints, your automatic alignment is complete.
Please rate this solution.thanks and good luck.

Scanner leaves three vertical lines on scanned page


Hello,

A dirty glass base can cause ‘spots’ or blemishes to appear on your final printout. Additionally, if you had some sort of opaque liquid that may have transferred on to the glass base from a previous operation. But the majority of the unwanted vertical lines are generally caused by either a dirty or damaged print roller or faulty LEDs in the Scanner Module.

To separate one from the other you have to check the following:

Do you only see the lines with a Scan operation?
Do your print jobs print fine without any unwanted lines?

If you only see the unwanted lines during a Scan operation, then most likely you have a fault/dirty/obstructed LED module.

If you see the unwanted lines with all print operations (Scan, Print and Copy), then you most likely have a worn out, damaged or dirty Print Roller.

Hope this helps…

Print Problem - vertical lines


If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
