Color print qualities issues

I have a CLJ2840. I have an intermitent print quality issue when I print color documents. I printed the self test/config page and some itmes it is almost ok but others the color is off. I am using HP supplies. I have replaced all 4 colors and the assembly with the drum in it. On the pages with an issue(using the config page) sometimes it seems to pink. the light blue square is pinkish as are all the purples. On others the entire page has a yellow tint(even where there should be no image). I have also run a calibration all this to no avail. Any help would be appreciated.

Perhaps you've tried, but check to see if your printer is printing color using the PS driver or the PCL driver. If you are using the PS driver the colors will not print correctly, but this is the best mode to print black and white since it will save your drum life and print faster.

My brother MFC 665CW printer shows a 4F error and unable to clean. How do I get to the head to clean it?


Do the following to clean the print head:


1. Press INK key on the control panel.


2. Press the DOWN arrow key until CLEANING appears on the LCD.


3. Press OK.


4. Press the DOWN arrow key to select BLACK, COLOR or ALL depending on what you want to clean.


5. Press OK.


The machine will clean the print head. When cleaning is finished, the machine will go back to Ready automatically. If you are experiencing a print quality issue, we recommend you repeat the print head cleaning for each color showing an issue at least five (4) times.


If you are experiencing a print quality issue and want to see if the cleanings are improving the print quality, print a Print Quality Check Sheet (PQCS) after the first cleaning and then print another PQCS after repeating the print head cleaning steps at least three (3) more times (4 total cleanings). You can then compare the two Print Quality Check Sheets.


Do the following to print a Print Quality Check Sheet:


1. Press INK key on the control panel. TEST PRINT will appear on the LCD.


2. Press OK. PRINT QUALITY will appear on the LCD.


3. Press OK.


4. Press COLOR START.


NOTE: The machine will generate the Print Quality Check Sheet (PQCS). On the PQCS each of the four colors is represented by a slanted square pattern made up of 96 individual blocks. The colors should appear (from left to right): Black - Yellow - Cyan - Magenta. Cyan is the light blue color and Magenta is the pinkish color.

Photos come out totally blurred with colors mixed. Happens on all sizes of paper (photo quality).


  1. Make sure that there is letter, A4, or legal unused plain white paper in the input tray.
  2. Touch Setup on the display.
  3. Touch Tools .
  4. Touch Self-Test Report . A self-test report prints. Figure 1: Self Test Diagnostic Pagec01154260.png
  5. In the Print Quality Pattern section on the test page, look at the color blocks for any lines. Figure 2: Print Quality Patternc01154261.png
  6. If there is no color bleeding in the Print Quality Pattern color blocks, print a document to determine if the issue has been resolved.
If you have completed all of these steps and are still experiencing a problem, continue to Step three. Step three: Check the paper
  • Many papers have printing and non-printing sides. Load the paper with the printing side down.
  • Use the correct paper type for the project. For everyday documents, plain paper works well. For documents with dense printing, such as high-contrast graphics or photographs, use HP Advanced paper for the best results.
  • If these steps do not help, try a different paper. Ink might not bleed as easily on heavier paper. Paper that does not accept ink well is also prone to bleeding and smearing. HP designs its inks and papers to work together.
If you have completed all of these steps and are still experiencing a problem, continue to Step four. Step four: Check the printer settings
  1. In the software program you are trying to print from, click File and then click Print . The Print window opens.
  2. Make sure that your printer is selected and then click Preferences . The printer Preferences window opens.
  3. Click the Printing Shortcuts tab.
  4. The Printing Shortcuts tab lists most printing needs, but you might need to modify some of the options. Options on the Printing Shortcuts tab:
    • General Everyday Printing
    • Photo Printing-Borderless
    • Photo Printing-With White Borders
    • Fast/Economical printing
    • Presentation printing
    • Two-sided (Duplex) Printing

    NOTE: These general printing shortcuts have pre-selected settings.
  5. To change the settings from the ones that are available on the Printing Shortcuts tab, click the Features or Color tab. Options on the Features or Color tab include:
    • Print quality : If you are unhappy with the quality of your printouts, try increasing the print quality. To print more quickly, try decreasing the print quality.
    • Paper type : If one of the options matches your paper type exactly, select it rather than Automatic.
    • Paper size : Make sure this matches your paper.
    • Print in Grayscale : Print a document in shades of gray.
    • Orientation : Specify how the document is positioned on the page.
    • Paper Source : Select the tray that you want to use for printing.
    • Two sided printing : Print on both sides of the paper.
    • Color Management : Specify the color space that the printer will use to interpret image data.
    • Pages per Sheet : Specify the number of pages of the document to print on each sheet.
If you have completed all of these steps and are still experiencing a problem, continue to Step five. Step five: Clean the printhead
NOTE: Do not clean the printhead unnecessarily because this wastes ink and shortens the life of the ink nozzles on the printhead.
  1. Make sure that there is plain white paper in the input tray.
  2. Touch Setup on the display.
  3. Touch Tools .
  4. Touch Clean Printhead . The HP All-in-One cleans the printhead and prints a test page.
Step six: Service your productIf you have completed all the steps listed above and are still experiencing a problem, service the product

My lexmark x1290 isn't printing tho i have new ink cartridges


It seems there is a possibility of a problem with the printer itself, or perhaps the cartridges. You should first self-test the printer. Since we are unsure where the problem exists, we must do eliminative troubleshooting to rule out parts of the printing system. The self-test allows us to rule out software and the cable by testing the hardware by itself. Please note that this is not a "fix," but rather a diagnostic test to determine if your hardware is at fault.
Please begin by disconnecting the power supply from the wall (not the back of the printer) for at least "30 seconds." Then plug the printer back in.
Next, try this printer self-test by following the steps given below:
1. Power the printer off.
2. Press and hold the "Paper Feed" button.
3. While still holding the "Paper Feed" button, press and release the "Power" button. Continue holding the "Paper Feed" button.
4. When the printer starts pulling paper, release the "Paper Feed" button. It should print a test page at this point.
5. Power the printer off, as this test is continuous.
The self-test should at least print out a set of either a solid black or solid color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, please try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with only a color cartridge installed (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed). If you find that either cartridge causes the self-test to fail, please let us know.
If the self-test prints, but has lines or smudges or other print quality issues, please let us know. This includes any print quality issues - we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.
If the self-test prints your test bar(s) clearly, the printer hardware is not at fault. The issue may be a communication problem, or perhaps a software conflict.

Print cartridge missing


Please remove the cartridges from the printer. Take a dry lint free paper towel and gently wipe the contacts on the back of the cartridge (not the bottom from where ink is present). Wipe the contacts inside the printer (on cartridge carrier). Please snap the cartridges back into the cartridge carrier.

1. Please turn OFF the printer.
2. Press and hold the "Color copy" button.
3. Now, turn ON the printer.
4. Once you see "0" on the display, release the "Color copy" button.
5. Press the Up arrow button until "2"appears on the display.
