I have a HP 8259 printer and it indicates the yellow print cartridge needs to be replaced even when i install a new cartridge. It will not let me print in color or black/grayscale. I have had the printer for a couple of years.

hp support>d 7360>software and drivers>diagnostic utility (2010-11-09). download (run). Test and print test page which is only one sentence. worked for me.

HP Business Inkjet 1100 stops everytime after the first line stars to print. The power is one, the ink drop light is lit, the "yellow" indicator light also on, and the paper light all on. None of them blinking. We replaced the yellow cartridge with a brand new HP 11 yellow cartridge. Turned the printer off and on to reset. Printer comes on everything looks good till you try to print anything, even a on line word doc? Then it happens again, so we replaced the yellow again...same thing. We ever cleaned print heads, Any assistance would be welcomed?

Make sure that printer ask for ink cartridges.It can ask for yellow and magenta print heads!!!Check this again and if need replace the print heads.

I had this same problem, replaced all ink cartridges and problem still remained. The fix for this is actually to replace the print heads not the cartridges. There is a black/yellow and Magenta/Cyan print head in the printer itself under the scanner on the right hand side. Rpelace as needed.

Are you using a factory new HP cartridge? If so, contact HP and request a warranty replacement of the toner cartridge.

The problem you are describing with the yellow cartridge sounds like ink starvation possibly due to a clogged print head or an air bubble in the print head. Since the machine is so new I would contact HP to get the print head replaced. As for the magenta cartridge, exchanging it for a new one at the store you bought it from should fix the problem. It sounds like the chip on the one you have is either damaged or wasn't set to read full ink levels.

I junked it!

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.

did you clean and re calibrate those print heads?

spounds like a defective print head bud. these do wear out and most of the time it will cost as much as a new unit.. Good Luck
