Introdução
If your HP B210a has a clogged printhead, this guide can be used to try and clear the clog.
IMPORTANT: This does not fix every printer. If your printer has predisposed hardware problems, this will not work. If the problem persists, your printer has a different problem or a bad printhead. It is typically more cost efficient to replace the printer as an entire unit if this happens.
Guide Notes
- WARNING: THIS PROCEDURE MAY DAMAGE PRINTHEADS WITH OTHER DEFECTS!
- If the printhead has failed, it likely had predisposed damage.
- This guide is primarily made for the HP Photosmart Plus B210a, it is universal among all HP 564 printers, as the same method can be used on other models.
- Non-removable printhead models (Ex: Photosmart 6520) require special attention to preserve the calibration. These may not work again if SETUP cartridges are expected.
- If I have not tested your specific printer with the bypass, I cannot guarantee calibration preservation. It generally doesn't hurt to try (removable only), but I cannot guarantee it will work.

When the printer is unplugged, remove the printhead. Lift the lever up and the printhead will be loose.
-
Remove the printhead as shown. IMPORTANT: Leave the scanner lid open to indicate the printhead was removed.

Using a alcohol wipe, clean the printhead interface. This will stop any Ink System Failure warnings from appearing.

-
Pour hot water into a bowl and let the printhead sit. Change the water until the printhead is reasonably clean.
-
Dry the printhead contacts and nozzles by hand to ensure these areas are dry.
-
Before reinstalling the printhead, let it air dry for ~3-4 hours. Use a fan to reduce the dry time.
-
-
-
Once the printhead is satisfactorily dry, reinstall the printhed and ink in the reverse order they were removed. Plug the printer in when installed.
-
-
-
After replacing the printhead, test the printer. Match the settings used before and check for improvement.

If your printer is working correctly, it was just a clog. Persistent issues usually total out the printer as a unit.

While/when soaking the printhead, I used a small intact artist's paint brush (no hairs falling out of it) to help loosen the globs of ink. I changed the water several times as there was a lot of ink.
Also, the first time I tried printing after soaking/cleaning the printhead (my issue was that the regular black cartridge showed it was NOT empty, but printing black documents wasn't working), I still had a blank page. Next I tried aligning the printhead but got a "failed," or similar, result. Next, I printed a "print quality report" from the printer's Tools menu and that seemed to be fine, so I tried printing the invoice I originally was having issues with, and voila, it worked!
Thanks.
Thanks this worked and all is well again
The one things that I had to do: I put the machine back together when it looked dry and the machine would not work. It refused the print head and complained that the ink packets were used. I tired it about 4 times with the same results. So I set it all aside and let it dry out over night. Wha La it worked. I put it all back together, the machine did it's thing and suddenly everything worked perfect.
Thanks again for saving me from having to buy a new machine.
HI, I am glad to find your explanation. I have followed HP's instructions, which didn't include soaking the print head, but will try that, too. What I am having trouble with now is that the printer screen says that "the print head appears to be missing, not detected, or incorrectly installed". I've redone it 3 times with no change. Also, the HP instructions did not say to unplug it and leave the cover open, so I left it plugged in and put the cover down. Since the printer is not recognizing the head, I have no way of telling if the alignment settings are messed up or not. Do you have suggestions for getting the printhead to be recognized? Thanks a lot.
Thanks so much!! It worked! Never would have guessed!!
I am using refilled cartridges for the Photo-smart 6520 all in one wireless (mainly) . I am trying to get the printer to not give me problems due to the chips being read by the system and knowing that they are previously used. I took the cartridges out last night and also the print head as described. There was a WHOLE LOT OF INK (mainly black) in several places inside the printer that I did not like. Even with the print head out, I had to continue to move the carriage and clean "leaked" drops of mainly black ink from the path on the metal part. I also had to carefully clean it from the white rollers. I cleaned so much ink from the print heat and it seems that the colors side it pretty much clean. It is the black side that concerns me. From underneath the print head, that nozzle seems to still have some dried ink there. I let it dry overnight, am in the process of a hard reset, and will be plugging it in again and inserting the cartridges during that process. I will try and check back for comments.
