Inconsistent color at times

[Dmf197220]

My color prints are coming out with inconsistent colors. I’ve tried cleaning the heads & aligning them. These are brand new cartridges & it did it with previous ones too. Any suggestions

Thank you for joining the HP Support Community.

To provide you with an accurate solution, I'll need a few more details:

Are you facing the same issue while making a copy?

Are you using genuine HP ink cartridge?

I suggest you do a Hard Reset

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

If the copy is working fine, Let's try to fix this issue by doing a clean install. 

Follow the steps mentioned below:

First, unplug the USB cable from the printer is present.

Go to Control panel - Programs and feature - Select your HP printer entries and uninstall them.

Now go to Control panel - Devices and printer - Select all the printer entries and remove the device.

Restart your computer.

Click the bottom-left Start button on the desktop, type device manager in the search box and tap Device Manager on the menu.

Once in device manager, click on the view tab in the top & choose "Show hidden devices".

Then from the device manager list, check the entries under "Printer" - If there are any entries, please right click and choose "uninstall" - In the confirm device un-install pop-up, make sure you select the box which says "Delete the driver software for this device".

Also, check the entries under "printer queue" and "imaging devices" and repeat the same exercise. 

Delete any printer entry or any entry which says "Unknown device".

Once done, close device-manger. 

Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.

Under print server properties, go to drivers - remove any entry there as well. Again, go to Run window, type - "c:/programdata" - Go to Hewlett Packard folder, remove any printer related folders & files.

Once done you can try cleaning out your temporary files and cached files. 

You can try using automated applications like some cleaner software's that you can download from the internet.

Now restart your computer again. Open the Run window again, type "services.msc" and press ok to get services window. Scroll down to "Remote Procedure Call (RPC)" - right-click and go to properties. 

Make sure the service is started and startup type is "Automatic".

Now scroll up and go to "Function Discovery Provider Host" - right-click and select properties - Change the startup type to "manual" and start the service.

Repeat the same exercise on "Function Discovery Resource Publication" as well.

Then, click on this link: https://support.hp.com/in-en/drivers/selfservice/swdetails/hp-officejet-pro-6830-e-all-in-one-printe... to download and install the printer driver.

Try to print.
