Replace the toner.
It sounds like it has a defect in the imaging drum that is in the toner cartridge.

How do I fix my Samsung Multi-function laser printer which has started to print smudged pages.


try to stop the sheet just before it enters the fuser and see if the marks are on the paper already. if not then it has to be the fuser if they are them you have another issue.

There are streaks on the side of the printed page


Hi,

Are the Streak lines vertical or horizontal ? Most likely it could be due to Toner issue, Try to remove the toner and clean it and re-install it

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.

Printed document has white streaks. I've replaced all toner cartridges AND replaced the toner waste unit. The streaking occurs when I print or copy but is much worse when I make a copy. Is there a printing...


If you are getting vertical white streaks or faded streaks from the top of the page to the bottom. It sounds like the developer blades in the imaging unit needs to be replaced. It cost around $120 to replace, but after a while it will happen again. This is a common problem with this printer. It can be cleaned by taking the unit apart and cleaning the developer blades, if you are handy. I have posted detail instructions in my tips section. or you can click on this link:

Hope this helps.

Vertical streaks when printing pictures


vertical lines on prints usually means either the drum's cleaning blade is not cleaning the drum (or the drum is damaged) or the fuser is scored. scored means that the protective coating on the fuser rollers is damaged. I would check the rollers on the fuser (the hot part of the printer right near the paper exit) for any lines on it, if you look at your prints, you should see them in the same location on the fuser. if you do not see any lines on the fuser rollers, then replace the drum.

Faded-out streak


check your ink levels. if its the ink that came with the printer it is probable running out of ink. they do not give a full cartridge with printers, only about 3rd full. also try cleaning the heads. and try changing your printer settings/prefrences to less ink, more drytime see if that helps.

When I print photos, they have uniform vertical streaks.


Issue: Banded or streaked prints
Solution: Change the Print Quality Settings (Windows)

Change the Print Quality Settings (Windows) The Quality setting controls how finely ink droplets are placed on the printed page. Depending on the type of paper being used a higher Print Quality setting does not always insure a better print. Print speed will decrease as the Print Quality setting is increased. Follow the instructions below to change the print quality settings in the Canon printer driver for the Windows operating system through a printing application.
  1. Click 'Properties' in the Print dialog box.

    Note: Depending on the Application software, 'Properties' may be displayed as 'Preferences'.

  2. Set the desired print quality in the 'Print Quality' section.

  3. Select 'High', 'Standard', or 'Draft / Fast'.
To set more detailed print quality settings, follow this procedure:
  1. Select 'Custom' and click 'Set'.

  2. In the Set Print Quality dialog drag the slide bar from 'Fast' to 'Fine' to select the print quality.

    Note: There are five options in 'Quality'. However, selectable options are limited depending on the media type.

  3. Select 'Auto', 'Dither', or 'Diffusion' from the 'Halftoning' section.

CLP-500 vertical streaks & a horizontal line with blotches appearing randomly


I've refilled the toner cartridges a few times now and never had a problem with vertical streaks until recently. I refilled both the cyan and magenta and when I ran the test page I had dark vertical streaks on both sides. I fiddled around cleaning things, running cleaning paper through, changing reset resistors but to no avail so eventually decided to buy a replacement refurbished cyan cartridge since the streaks looked mainly blue and bingo... well almost now I just have very light magenta streaks. The issue is obvious when I compared the old and new cartridge, the replacement toner is a much duller cyan and is of the wrong consistency since once it's been in the printer everything gets covered in it which is why I think it causes the banding to occur. I'm just trying to work out now whether to try refilling the magenta again (v. messy) or just go for another refurbished cartridge (£34).
