My printer has been leaking black ink onto every sheet that it prints for the last month or 2. I've been very busy so left it. It also was a small area before approx 1/4" x 1/2" average each piece of paper that printed. But now it getting worse and is more like 2" x 1/2" leak on each page in the top left corner of each page that is printed.
I did the realignment, 1st cleaning & secondary cleaning that the printer can run. None of this helped.
What can I do to resolve this problem and what is the problem?
Let me take a moment to thank you for posting on the HP Support Forums.
I understand that you have an HP Photosmart 7520 e-All-in-One Printer. I read that the black ink leaks onto the paper while printing. I read that you have aligned the printer and have performed the cleaning. Fabulous analysis. Spectacular diagnosis of the issue before posting. Kudos to you for that.
To provide an accurate resolution, I need a few more details:
Are you using original HP cartridges or refilled ones?
Have you tried replacing the black cartridge and check?
Meanwhile, I suggest you to perform the following steps:
Disconnect the power cable from the printer while the printer is still ON.
Disconnect any other cables if connected the printer.
Press and hold the printer’s power button for 15 seconds.
The printer should be directly connected to the wall outlet and not to a surge protector. Reconnect the power cable to print and the printer should power ON by itself. If the printer doesn’t power ON then please manually power it ON.
Please try to clean the printhead manually.
Remove the cartridges out.
Remove the printhead out.
Do not touch the ink nozzles. Release the latch towards the right side to remove the printhead out.
User a damp, lint-free cloth or cotton swap to clear the area around the ink nozzles on of the printhead.
NOTE: DO not touch the ink nozzles and the electrical contacts of the printer. Do not place the printhead with the ink nozzles touching the surface.
Let the printhead dry. The insert it back into the printer and also insert the cartridges and try to print.
I hope this helps. Please feel free to keep me posted. Cheers!
