A technique to improve print quality is to try and clean the cartridge nozzles. You may clean the cartridge by following the steps given below:
1. Go to the "Lexmark solution center." This can be done by clicking on "Start," go to "Programs" and Lexmark printer group. Click on the "Lexmark Solution center." Next click on the "Maintenance" Tab.
2. Select "Clean and Fix Horizontal streaks." Click on "Print". This will produce a printed page.
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.
If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzle" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:
1. Please open the "Solution center" again and go to the "Maintenance" Tab.
2. Select "Install color/black cartridge" and remove the cartridge or cartridges from the printer.
3. Get a damp paper towel.
4. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
5. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
6. Next dab the cartridge on the towel to make sure that the ink is flowing.
7. Snap the cartridges back into the printer.
8. On your computer, select "Old Cartridge install."
9. Repeat the "Clean Nozzle Page" one more time. If this fails to address the problem the entire procedure may need repeating.

Good Luck!!!!

This is coming from the toner cartridge. Replacing the cartridge will fix this issue at leat 95% of the time. This problem is caused by a defect or damage to the drum in the toner cartridge. If you have a new spare then just swap them out. If you do not have a spare even an old empty cartridge can be installed to verify that the cartridge swap will resolve the problem.
Good Luck and Thank You for using Fixya.

Ink tends to overflow at the bottom guide rollers and the roller gets coverd in ink and causes the black line!The best will be to take it to a dealer and have it cleaned!Good Luck!

Do you refill ink tank? Print blank pages. Is there horizontal lines appear? It might be caused bay ink leakage. Check respiratory hole at ink tank and rubber seal at bottom of ink tank. Print blank pages until no horizontal lines and try to use new ink tank.

This is probably due to a defective cartridge, Charge Roller or Transfer roller.

Check the cartridge for a band of toner still on the drum.

Check the Charge roller for oil or smudges, this roller should be a lighter color and should be relatively free of toner or marks.

Same as the Transfer Roll, which will be dark, though excess toner should be evident.

A relatively smooth straight line is generally the cartridge.

A rather wavey or broken line is most likely the rollers.

You can however attempt to print a large amount of pages (25-50) in an attempt to clean the parts, however if either part is defective they will need to be replaced and no manner of printing will clean them.

Hi,

You can easily fix this yourself, one of the quickest ways to fix it is to print 10 doublesided blank pages and it will clean the inside of the machine for you and the line will vanish.

For further print quality problems on this machine follow these instructions to troubleshoot.

When troubleshooting image quality problems, it is important to understand the situations in which the problem occurs.

Print a copy of the color test pages to determine whether the problem is in one color or more than one color.

1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
3. Press the [Up] or [Down] arrow button to select [Color Test Pages], and then press the [OK] button to print the test pages. If the problem occurs with one color on the test pages, perform the solutions for this problem. If the problem occurs in more than one color on the test pages, restart your search and select a case for the image quality problem occurring through all colors.

Resolving white, light lines or streaks (eliminate light stripes)

From the printer, print the Troubleshooting Print Quality Pages.
With Troubleshooting highlighted, press the OK button.
Scroll to Print Quality Problems by pressing the Up or Down Arrow button. Press OK.

Scroll to Troubleshooting Print Quality Page. Press OK.
Evaluate the Light Stripes Test page for missing printhead jets (missing cyan, magenta, yellow or black color bars).

Clean the maintenance unit's wiper blade and empty the waste tray. A dirty maintenance drawer wiper blade can cause white lines and weak or missing printhead jets. Using a clean lint-free cloth or a paper coffee filter, gently clean the blade with a wiping motion across the entire length of the wiper blade.

This can be caused by one of two things.

1. faulty wiper blade on your toner so that the previous image in not being wiped off the drum.
2. worn fuser sleve.

To work out which it is you will need to do a half stop test: print off a normal document then when it is about half way through the printer ( unfortunatly you may have to repeat this to get the timing right) open the front cover. remove the toner cartridge. if you can see the ghosting on the page the it is the toner. if its not there then its a new fuser. to save on money and if your confident enouh you may be able to just chane the fuser sleve depending on the state of the fuser on a whole.

hope this helps

I ran the hp toolbox "cleaning" mode too and it did not help the problem at all. I still have a dark smear concentrated in the middle of the page, and ghost images repeated lighter all the way down the page.
