One color fades inside solid regions in 10mm bands

[PETERK9]

When there is a dark blue region, the blue fades to 0% in a patch centered in the blue region, but only in regular 10mm high bands. Light blue solid regions do not have the problem. The fading is not specific to any horizontal offset within the page,

Faded bands within solid region

All possible print cleaning and alignment has been performed many times and the blue ink cartridge has been replaced, all without success. The problem persists when printing for 2 different computers using different document software. The printer has been working fine for years and developed this problem in October 2020. The firmware is up to date and the driver software on both computers.

Welcome to the HP Support Community.

Does this only happen with these bands? Are you otherwise able to copy and print well?

Let us know 🙂

Thanks!

[PETERK9]

Yes - it only seems to happen with this specific color or near that color in more or less solid areas. I have not had any problems printing otherwise.

[Betty0610]

Where you able to ever print on these bands before?

[PETERK9]

Yes

Let's try to do a root uninstall and reinstall of the software:

Unplug any USB cable, if any, before doing this.

1.) In Windows, search for and open Programs and features

2.) Select your HP Printer

3.) Select Uninstall

4.) In Windows, search for and open Devices and printers

5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose 'Delete' or 'Remove Device'

6.) Open up the run command with the "Windows key + R" key combo.

7.) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”)

8.) Click on the "Drivers" tab

9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom

10.) Select Ok

11.) Select Apply and Ok on the Print Server Properties windows

12.) Close Devices and Printers

13.) Open up the run command with the "Windows key + R" key combo

14.) Type c:/programdata and click Ok. Go to Hewlett Packard folder, remove any printer related folders & files.

15.) Restart the computer.

Once done, please download and install the software from here:

I followed the directions below and completely removed HP driver and other software from my computer. After rebooting, I installed the latest driver. I noticed that there was a firmware update available and tried to install it, but the program said that my firmware was already up to date. The image below shows the original graphic and what i get when I print.

I would request you to change the ink and try printing.

Replacing the ink did not solve the problem
