I changed the cartridge but now it only prints with yellow color

Hi,

This is not a cartridge issue. IT is Printhead issue. Since you have done the manual cleaning, it is now time to replace the Printhead.

Hi,
The inkjet printers print colors as they combine the major 4 colors contained in the cartridges CMYK (or said in words cyan, magenta, yellow and black) in some proportion.
If you print black the printer gets ink from the black cartridge only. If the black cartridge is empty some devices start to print black as a combination of the colors in the color cartridge - for example gets some of the cyan, gets some of the magenta, gets some of the yellow.
In your case maybe some of the other colors are empty too (or the nozzles are clogged) and the printer cannot prepare the correct mixture of colors to start printing black.
I suggest you to change both black and color cartridges.
Hope this helps.

Either the ink you are using is not going to give the color you want, or you have print heads that are blocked.

This just started happening to me also, I have been using the printer without issue for a few years. Replaced the yellow cartride, still no yellow. Anybody else seeing this?

slowly off and on the printer for five times without cartridge, printer saves data of cart of last 5 only so next time it reads full ink..

Your yellow cartridge is probably not working as your photos suggest. Remove and reinsert the yellow cartridge. Try printing only yellow color.
Your printer has a separate head for printing; the nozzle for yellow ink might be clogged. Try running a head cleaning routine from your printer software.

try another yellow cartridge,because if u are using generic cartridges from the same vendor,they might be defective.

HP Color LaserJet 2600n Printer - Installing Print Cartridges When a print cartridge approaches the end of useful life, the control panel displays a message recommending that to order a replacement. The printer can continue to print using the current print cartridge until the control panel displays a message instructing to replace the cartridge. The printer uses four colors and has a different print cartridge for each color: black (K), cyan (C), magenta (M), and yellow (Y). Replace a print cartridge when the printer control panel displays one of the following messages: Replace yellow cartridge, Replace magenta cartridge, Replace cyan cartridge, Replace black cartridge. The control panel display also indicates the color that should be replaced (unless a genuine HP cartridge is not currently installed). Change the print cartridge

1. Turn off the printer.
2. Open the front door. CAUTION: Do not place anything on the transfer belt (ETB), which is located on the inside of the front door.
3. Remove the used print cartridge from the printer.
4. Remove the new print cartridge from the bag. Place the used print cartridge in the bag for recycling.
5. Grasp both sides of the print cartridge by the blue handles and distribute the toner by gently rocking the print cartridge from front to back. CAUTION: Do not touch the shutter or the surface of the roller.
6. Remove the orange shipping locks and the orange shipping tape from the new print cartridge. Discard the shipping tape and shipping locks according to local regulations.
7. Align the print cartridge with the tracks inside the printer, and using the handles, insert the print cartridge until it is firmly seated.
8. Firmly close the front door.
9. Turn on the printer. After a short time, the control panel should display Ready.
   NOTE: If a cartridge is in the wrong slot or is the wrong type for the printer, the control panel will display one of the following messages: Incorrect yellow, Incorrect magenta, Incorrect cyan, Incorrect black.
10. Installation is complete. Place the used print cartridge in the box in which the new cartridge arrived. See the enclosed recycling guide for recycling instructions.
11. If a non-HP print cartridge is in the printer, check the printer control panel for further instructions.
    NOTE: When replacing or changing a black print cartridge, a cleaning page will automatically print. This helps prevent speckles on the front or back of printed documents. A cleaning page can also be generated using the control panel or the HP Toolbox.

I came up with a work around for printing black.

I changed the black cartridge with the color cartridge.
Then when I have a letter to print, I change change (or write) the letter text to yellow, red or blue.
Then I can print out a letter.

By printing the text as yellow, red or blue the cartridge will try to print with only 1 color, but will print out black.

If you do not use one of these primary printing colors the out put will be unusable.

I can not of course print out pictures.

You are using HP's cartridge with the smallest output . So if you are printing 80 pages of text, you will have a problem by the time you reach 95 or 100 pages. If you are printing in color, you only have 1ml/color. Meaning 3 colors. But in order to print a red, it will combine a magenta and yellow to product 1 color. So 3 colors doesn't mean 3 ml worth of colors. Effectively you may only be able to print 10-20 pages of color then your cartridge is empty. The black cartridge has about 4-5ml of ink. So if you print a lot I suggest you get another printer.
