ENVY Photo 7855 printing is streaked and unreadable

[Gilbert88]

I bought the printer about a year ago and the black ink was changed around 6 months ago with about 3 quarters full currently.  I use it infrequently but when I tried to print my document today, the printout is streaked and unreadable. I cleaned and aligned the ink jets but it didn't help. It seems to me the problem is from the black ink cartridge.  Is there any thing I can do to fix the issue?

Thanks.

I understand the print quality is not good. Make sure you have tried the steps mentioned in this document - Black or Color Ink Not Printing, Other Print Quality Issues

Clean the black ink cartridge 2 times and print a test page to check the result.

Try making a standalone copy from the flatbed glass and check if that prints fine. By this, we can conclude if this is a hardware or a driver issue.

if you have an alternate black ink cartridge, check if that works fine.

Hope this helps! Keep me posted.
