Hi. My Lexmark C510 always produces horizontal lines down the left margin of each page. Looking at the "drum" (not sure of exact name, but it's the part right behind the 4 toner cartridges) I can see the impressions of these lines all the way down the left side. So it looks to me like that part needs to be replaced. I don't know why this occurred, or exactly how to fix it. Any help would be appreciated. Thanks.

Re: Horizontal lines down left margin
Sounds like it's a transfer belt and not a drum you are refering too. Each toner cartridge mose likely has a drum built into it. If the lines are only in one color it may be that toner that is bad. But most likely it's the transfer belt, often called an ITU (Image Transfer Unit) or ETB (Electrostatic Transfer Belt). They sometimes get contaminated with dust, oils from fingers, etc... and can't be cleaned, would need to be replaced.

Many times horizontal lines -- esp if constant (e.g. 4 inches apart) appear-- on laser printers indicates a drum issue. NOT usually inexpensive. Sometimes one can dis-assemble part of printer and clean drum with soft cloth and therefore "buy some time"
You can clean the cartridge using the following steps:
Click on "Start," go to "All Programs," and down to the Lexmark. Click on the "Solution Center." Next, click on the "Maintenance" tab. Select "Clean to fix horizontal strips." 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 to fix horizontal strips" 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. Also, wipe the contacts inside the printer (on cartridge carrier). 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 to fix horizontal strips" one more time. If this fails to address the problem, the entire procedure may need repeating.
This sounds like a cartridge problem if you have changed the cartridge and the problem persists I would say it is the positive charge roller inside the printer. If you open the cartridge door and remove the cartridge with the cartridge out starting closing the door and you will see this roller moving down from the top inside of the printer. do not touch this without a glove or lint free cloth. not hard job to change if you can get one in your area if not we have them available. laserguy@nbnet,nb,ca
