Question about HP Officejet Pro 8500 Wireless All-In-One InkJet Printer
HP 8500a-910a just replaced both printheads and new hp ink and everything was good for about a week then suddenly the cyan stopped printing.
Hi I have two split pipes in my Hp 8500A printer where can I get replacement parts as it is not printing correctly.

Good advice, but HP refused to replace the printhead despite the fact that it is still under warranty (expires 4-7-10). Tech support (very hard to understand) said I would need to buy a new printhead to confirm that the problem was not the printer itself. When I asked about this, they cut me off.

Hi Paula, first of all, take out the Continuous Ink System. Second, make sure that the new printhead are good and work propretl, try to get them in another HP 110, if their work good and at your HP not working good whitout your Continuous Ink System replace the carriage assesmbly, but before that verify tge tubes of ink. Good look

Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

SOURCE: k550 air in ink feedlines
I have had this happen a couple of times and have cured it easily. It has only happened with the black with me. It seems to be caused by air in the ink feed line. With the printer switched on open the top cover and hold the resume button for 5 seconds. The printheads should move to the left and you may be able to see air in the pipe(s). Remove the printhead of the offending colour(s) then insert a syringe with the plunger fully down into the rubber that the printhead connects to. Draw up the syringe plunger to draw ink/air through until you can see no more air in the pipe. Replace the printhead and close the cover. The printer should now do a calibration with the offending colour hopefully now working.

SOURCE: printing yellow for black
Can you confirm that you are using a CIS or non-HP cartridges with this printer?
It sounds a lot like the printhead has reached a clogging point where sediment has built up in the black portion and loosens enough to printer a few lines before it re-asserts itself again.
Based on my experience of this printer, if you're using a non-HP delivery system for ink then you should consider replacing the black ink with a dyebase alternative instead of pigment.. Replacing the Black/Yellow printhead and running a number of test prints to purge the pigment ink in the printhead should then result in a clean and more reliable printout in future.
One other vector for problems is the cleaning area and I've found that this can become soiled with excess ink causing cross contamination within the inks of one printhead. As yet I've not found a reliable solution to counter this sort of issue.
Hope this gives some clues and hopefully some ideas of a fix.
