Printer Trouble My printer has gaps going through sentences in my documents. The lines are horizontal through the whole sentences. Please advise

soak cartridges in isopropanol

This is the same problem. You need to run the cleaning cycle on the printer. Go to Control Panel > Printers > Select your Printer > Printer Properties > Maintenance > Clean Print Nozzles.

Sounds like you need to do a head clean, and run the align tool

horizontal lines mean that there are inks overflowing on the print head and has some ink on a part of the printer where the paper is coming out while gaps are clogged heads. You may need to clean the print heads. I suggest to go to your local store and get kleenex with some distilled water and wipe the head area to take the lines out. for the gaps, just do a standard cleaning of printer heads using the software provided with your printer.

hi..

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.

try out..

Uninstall the printer driver completely, then reinstall the driver again.

DId you use a refilled or 3rd party cartridge?
