I have been having ink problems with my printer recently where it does not print yellow (despite printing the other two colours in the cartridge fine) and black.
I have replaced the black ink and it seemed to fixed the problem until yesterday when I went to print a powerpoint document and it printed one page and would not print anymore. The only page that came out was covered in black squares randomly (about 1cm x 1cm) that appear to be ink marks.
This is now happening on any document i print even the test pages
Please can you suggest what may be causing this/how i can fix it. Thank-you.
