Officejet Pro 6978 has stopped printing blue

6978
Microsoft Windows 10 (64-bit)

Hello, my inkjet printer has decided that it does not want to print blue.  I was attempting to print 3 photos.  The first photo top half printed ok.  The bottom got streaky (red, thicker on the left).  The second photo continued the streaky and the bottom quarter was a washed out red.  The 3rd photo was completely a decent print, but it looked like it was printed with a red filter.

 

My printer reports that all three colors are approximately half full.  I am enrolled in Instant Ink.  I removed the blue cartridge and when I touched the reservoir output with a tissue there was definitely ink there.  While it was out I trimmed the orange tabs around it.

 

Once I put the cartridge back in - still no blue.  This unit is 4 days out of warranty, has about 50 pages total printed over the past year. 

 

Any advise?

Hi @Andas

Welcome to the HP Support Community. I'd be happy to assist you. Let us try these steps to resolve this issue:

  1. From the printer control panel, open the Setup  menu.

  2. Open the Printer Maintenance menu.

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

  4. 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.

Also, perform step 9 from this document.

 

Now, Print a Print Quality Diagnostic Page

  1. From the printer control panel, open the Setup  menu.

  2. Open the Reports or Tools menu.

  3. Touch Print Quality Report. Check for blue.

 

As the issue is related to Instant ink cartridges, I need more information to help you out.

Thank you.  The 3 cleaning cycles resolved the issue.  It did take all three, but now it is printing very well.  I appreciate your quick response especially during the US Christmas holiday.
