Question about HP Officejet Pro L7590 All-in-One InkJet Printer

1 Answer

Black does not print out correctly

The page comes out smeary looking and very sparse. It looks like someone dragged the ink across the page lightly. I have checked all the heads and run the tests in the manual but I can not seem to fix the problem. On the test page the yellow and fushia seem fine. There is no cobalt color and the black is very streaky...like the print jobs I have tried.

Photos are light with fine grainy appearance. Have tried the corrections in the manual without correction.


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!!!!

White lines across print


If you lay the print on the exit tray face up and open the cover. Look on the encoder strip, the clear plastic strip behind the carriage, you should see an ink or grease spot right above where the bad spot on the page is. Wipe the encoder strip with Q-tip or wiper with alcohol. Prints should look better.

If your color improved slightly when running the printhead option then doing more should help get better results. Sometime the printheads get really dirty/clogged and running the cleaning option more then once is needed.

If you get a slight line running across the page (from left to right) usually the indicates dust build up on the printhead or ink carriage. The dust acts as a paint brush being dragged across your paper as the carriage moves across the page during printing. You can clean the bottom of the carriage with a Q-tip or purchase some cleaning paper for your printer.

Print faded after replacing black cartridge Brother 240C


The print heads don't appreciate being out of ink so the Brother printer has sensors to prevent that but the tape defeated that prevention. Maybe more cleanings or maybe a cartridge with printhead cleaning solution will help. Otherwise, I fear a new printer.
