Won't Print Black even after changing printhead

Last week the printer stopped printing black. The colors still print fine. I have gone through the print head cleaning like 10x, new cartridges. I even got a replacement printhead and it still won't print in black. HP phone Support was useless. He tried to sell me a service call then tried to sell me a new printer. If I need a new printed I'll buy it myself.
Are there any solutions or fixes? To repeat - I cleaned the printhead multiple times, installed new cartridges and installed a new printhead. I even removed and reinstalled the printer
I am really starting to hate HP products

Was the replacement printhead new from HP or a reman from a third party?
I would suggest checking the black cartridge vents as described in the document here. If that does not resolve the issue then soaking the printhead as discussed in the post here may help.

Office Jet 6500 E710n-z won't print black even just replace the ink cartridge with a new one.

It is the 3rd time to have problem on printing "black" even the ink is not empty (but the level is low, like a quarter left). In the previous cases, I replaced the cartridge and the problem solved.
The 2nd time was last week. After I changed the cartridge, it worked (for only 1 week) and the problem is back. Since the ink is full this time and it worked well when I just changed it, I suspect this is the problem of my printer instead of the cartridge.
I did clean printhead and align printhead but the problem persist. Please advice the solution. Thanks!

Hopefully the printhead does not need replacing. I would look at this document on defective output for your printer model. I know that some of the steps in here you have mentioned already performing. Please just read over/skip those and try the ones you have not yet performed. It shows different ways to clean the printhead; if you just did the cleaning from the toolbox I would defiantly do the manual one. It also has a walk through to make sure that the products firmware is up to date. Here is that link: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02455482&tmp_task=solveCategory&cc=us&dlc=en&la...
I hope this helps.

Why do Photosmart 6510 printers usually fail to print black (even after trying all ideas)?Help!

Photosmart 6510, new.
new cartridges. Prints colors great. Black -- a bit of spotty black then nothing. Replaced the new black with another new black cartridge (HP 564).
Result: Colors still work great. Black -- blank pages, nothing. Did all ideas in forums. All. Clean from the menu, you name it.
Judging from the many, many people having the same trouble. HP should recall this printer!
Or will we have to conclude (after owning a dozen) that HP no longer makes good stuff??

Same thing here... And they alway take you through time wasting twists and turns again and again Let's get to the point: This and apparently many other HP models have grave print head clotting/clogging/getting obstructed problems, for models with removable printer heads, you can remove it, soak the nozzles in hot water and they'll get un-clogged it seems, but what about 6510's un-removable printer head ?! Thumbs up if you think this is an under-par product which should be recalled. People have bought printers TO PRINT! not to do kitchen work with boiling waters...

Re: My Photosmart 6510 won't print black even with new black cartridge

The printer has been acting up over the past 3 months. Now it has stopped printing with a brand new black cartridge also new coloured ink cartridges.

@BigFraz
Have you tried the troubleshooting steps in the link below....

Is the printer in warranty?

Been through all steps. Cannot find levers.The printhead on the Photosmart 5510 is not removable. For the Photosmart 5510 the troubleshooting steps in the document here may help. Especially make sure the vents are cleared. If that does not resolve the issue then resetting the printer as described in the post here may help. If this does not resolve the issue then read the entire thread here and try requesting reset instructions. If your printer is under warranty I suggest you contact HP for warranty service. If you are in the US call 1-800-HPINVENt, elewhere see the contact information here.

I have vertical lines when printing even after changing cartridges.

I have vertical lines when printing even after changing cartridges. There are no lines when copying, faxing or scanning, only printing. I have cleaned the glass, scanner and even dusted where the toner cartride slides in. Any suggestions?

Sorry but I have worked on laser printers for over 20 years and never encountered your issue. That is of course if you are explaining it correctly. When you make a copy to be printed or print a reports page from the printer or send a print job to the printer, if in all these cases you get the line, then yes the issue is either the toner cartridge or the fuser. If you make a copy to be printed and it prints without the line (Put original in adf, press copy button and print should come out), then you have one weird unit since it does not make sense since the print formatter on the unit whether making a copy or printing from the computer or unit itself uses the same hardware. Now to test if the printed copy has a line then just put a sheet of paper on top of the feed tray and do a self test from the printer. When the back edge of the paper enters the printer, quickly open the toner door to stop the printing. Remove the toner cartridge and look at the image below. If the defect is present the toner cartridge is the issue and if the image below does not have the defect, then the fuser needs to be replaced. Best I can do. Good Luck.

HP Photosmart 6510 won't print black ink

I changed the ink cartridge in my printer and it won't print black ink now.
I have used almost an entire cartridge of my color inks running alignments and cleaning the printhead. I have also cleaned the print head with a cotton swab and some warm water.
I have delted the software and reinstalled it.
I have always used HP cartridges.
The printer is out of warranty. I'm in the US.
I have also ran every reset I can find online, nothing is working.
I appreciate your help as I am a broke college student and can't really afford a new printer at the moment.
Thanks!

Hello @valster101 and welcome to the HP Forums!
One thing I see that hasn't been tried is checking the vents on the cartridges. Please have a look through this Printer Prints a Blank Page or Does Not Print Black or Color Ink for the HP Photosmart 6510 e-All-in...s document to make sure you have tried all of these steps at one point or another.
If it still won't print black after that, just let me know and I'll do my best to get you a resolution

C4680 All in one won't print black

C4680 printer shows low black ink level, and won't print black. Prints color fine.
Already have tried the following:
Printer stopped printing a letter, showed low black ink level.
Purchased and installed new black ink cartridge, still won't print black, still low black ink indicator
Did printer cleaning three times. No help
Switch off, remove cables etc as recommended on HP site. No help.
Completely deleted printer from devices and reinstalled. No help.
Called HP help, after 30 minutes of BS told me cartridge was low after I told him three time I had just bought and installed a new one.
It will not copy black either
Any new ideas?
Thanks.
Bill

Clara- I did call phone support as I stated in my post; and their response was extremely irritating, just like your last post. Told Surha the phone guy all that I had already done and he kept telling me to do the same things. Didn't even say, I know you did this but let's try it again.
I clearly stated in my post that I purchased and installed a new ink cartridge, didn't help. I appreciate your trying to help on your own time possibly, but READ THE POST. I am aggravated because I have a problem and you are telling me to do things that I have already done that didn't help.
If you have something new to suggest, great, that's why I am contacting HP. If not just say, "yeah you have tried everything that they tell us to go through. You may need to take in to a service depot or just buy a new printer. Sorry."
By the way, there are several reports on other internet sites of the same problem with no solution. HP obviously has no clue. Hope someone in engineering or wherever is looking into this.

Photosmart 5200 won't print black ink

Hi there, I purchased the printer just over a year ago. It hasn't been used much at all. For the last few months I have continuously changed the black ink cartridge as it is saying it is empty or low and it still won't print black. The colour functions fine. I have tried all the settings options of cleaning and aligning and it doesn't make any difference. I only print via air print from iPhone and iPad, and the documents sent are extremely basic word docs. The printer is in perfect condition and I am out of warranty. Please can you advise how to fix as I rely on the printer for my invoices! Thanks

Hello,
Since you have replaced Black ink cartridges and tried performing Clean Printhead and issue still exists, i'd suggest you to call HP Tech Support for further assistance.
If you are in US , the toll free # is 1-800-474-6836 .
If you are not in US , then log on to www.hp.com , at bottom-left corner there is a world map icon, click on it and then select the region you belong to, which would then provide support options for you for that region.

Photosmart 7520 won't print black, says I have half a cartridge

My printer won't print black (regular, not photo black). The ink level says I have half a cartridge. I have tried cleaning the heads so many times but no change. I tried to find an answer in the help section of HP and had no luck. I tried to contact HP but was told because my printer was out of warranty in January I would have to pay to talk to someone. Can anyone help? I'm disappointed in HP, charging people to talk to customer service is ridiculous.

The steps in the document here may help resolve black not printing on your Photosmart 7520 printer. Be sure to check the vents as shown in Solution Six.
If the above does not resolve the issue then soaking the printhead as described in the post here may help.

6150 All-in-One won't print black

My HP Photosmart 6150 All-In-One won't print black. There is a new black cartridge and all the other inks are fine as well. I've cleaned the printhead 3 times and all that printed was yellow. I then ran an alignment. The alignment failed, but it wasn't because of a paper issue. The manual says it could be that the printhead assembly or the sensor is defective. Is it worth getting that fixed, or should I just get a new printer? I've had this one for 8 years and it's worked great until now.

Hi , Welcome to the HP Forums! I noticed that your HP Photosmart c6150 will not print black. I am happy to look into this issue for you! According to this guide, Color Mix or Missing Colors on the Diagnostic Page, it states: Missing colors occur when the printhead nozzles dry out. Since you have tried cleanign the printhead multiple times, and the issue is still occuring, I would consider having the printer serviced/or replaced. Please contact HP, phone support for further assistance. (After you fill out the information, you will be given a phone number.)

HT1491 My password in iTunes will not work, even after changing it. It keeps showing a window to add PW. I do and it pops up again.

My PW in iTues will not work. Even after changing it. Window pops up and ask for PW. Over and over.

I would be worried about that - but it may turn out to be nothing.
Since you already changed your password, you're probably OK - but I recommend looking at your purchase history to see if there's any unauthorized purchases (use iTunes on your Mac or PC to go to the itunes store, then click your account in the upper-left or upper-right corner). If there are any new purchases that you didn't make, click the button to report problem (and if they happened after you reset your password, you should immediately change your password again).
I think sometimes when you change your password and verifiy your credit card info, it can "reset" the warnings - so it may actually have been you logging in to your own account that caused you to get the warning. But I'm not absolutely sure of that, so it's best to check your purchase history (and reset your password if necessary - but you already did that).
I also recommend turning on "two-step verification" (but Apple makes you wait a few days after changing your password to turn that on). With "two-step verification", Apple will send you a text message with a 4-digit code the 1st time you try to buy something from a new computer - since a hacker won't have your phone, they won't be able to continue (theoretically). After the 1st time, it goes back to mostly working normally (until the 1st time you try to purchase from another new computer, then you get another text message - so this alerts you to someone, somewhere else, trying to get into your account).

Issue with printing production order after changes through CO02

Hi,
Currently I have one issue with printing production order changes through CO02. If I go for print, all the operations are captured in printout. But after the print, if I add any new operations to this production order, and then go for print, its not capturing the newly added operations. Also, there is information popup coming "Copies will be printed for order. Original list already printed". This message effectively means, even after changes, when I go for print functionality, its just going for printing copies of original printed list.
Can anyone help me out to get the newly added operations reflected in the print through CO02 ?
Regards,
Shiva

My remote wont turn the appletv on even after changing battery and unplugging everything and plugging it back in

my remote wont turn my appletv on even after changing the battery

Nothing, the light didn't flash at all? If so you either have a dead remote or a dead Apple TV.
If you have a Mac you can try pairing the remote with it to test. Go to System Preferences->Security & Privacy and unlock the panel. Click the Advanced button and look for the Disable Remote Control Infrared Receiver checkbox. Clear it and click the Pair button. If the remote is ok you should be able to pair it to the Mac.
If you can't pair the remote it most likely pints to a bad remote. If the Apple TV still won;t respond then you need to get the Apple TV looked at.
Good luck
