Pink lines appearing on the colour blue on my printouts all ink cartridges full

[Trevor14]

Whenever there is a colour blue in my printouts there appears a pink set of lines through the blue. It's driving me nuts. Can anyone help, please? All the ink cartridges are full.

Hi @Trevor14

Welcome to the HP Support Community. 

I understand that you are facing print quality issues. I'd like to help!

Please follow the steps below. 

The quality of a printed document or photo is not as expected. The procedures in this document should help with streaked or faded printouts, color or black ink not printing, documents with blurred or fuzzy text, ink streaks or smears, and other print quality problems.

NOTE:

If you see an Incompatible, Incompatible Cartridge or Defective Cartridge message for the Cyan cartridge and have an HP Officejet 6810, 6820, 6950, 6960, 8010, 8010e, or HP OfficeJet Pro 6230, 6830, 6960, 6970, 8020, 8020e, 8030, or 8030e series printer, see HP OfficeJet Printers - 'Incompatible Cartridge' message for more help.

NOTE:

If you see an “0x6100004a” error, your printer must be serviced. See the step at the end of this document to contact HP for service.

NOTE:

Rough handling at the store or during installation can cause print quality problems with newly installed ink cartridges. If you see print problems with newly installed ink cartridges, wait for a few hours for the automatic servicing routine to complete, and then try to print again.

Step 1: Reinstall the print driver (Windows only)

If you cannot print color from a Windows computer, uninstall and reinstall the printer software. Skip this step if your printer is able to print in color.

Remove the printer from the devices list.

For steps on removing the printer from the devices list, go to Uninstall HP printer software and drivers.

Go to HP Customer Support - Software and Driver Downloads, and then install the latest software for your printer.

Try to print. If these steps resolved the issue, you do not need to continue troubleshooting.

Step 2: Clean the printhead

The printhead could be clogged, and you might need to clean the printhead several times to restore print quality. Use an automated tool from the printer control panel to clean the printhead.

  CAUTION:

Never turn off the printer when ink cartridges are not installed. To avoid issues that require cleaning the printhead or that can damage the ink system, always replace ink cartridges as soon as possible, and always turn off the printer using the Power button.

From the printer control panel, open the Setup menu.

Open the Printer Maintenance menu.

If necessary, open the Tools menu, and then touch Clean Printhead.

A test page prints.

Examine the test page.

If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. If necessary, repeat these steps for the third cleaning cycle.

NOTE:

If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes before you perform all three levels of cleaning again.

If the print quality is acceptable, touch Done.

Try to print. If these steps resolved the issue, you do not need to continue troubleshooting.

Follow the remaining steps from the document. 

Hope this helps! Keep me posted for further assistance.
