HP L7680 does not print yellow

[Gatehouse]

Hi ....

My printer does not appear to print yellow.  Steps I have taken are:

1) I created a document inserting 3 squares each one filled 100% with cyan magenta and yellow. The results of the print out showed that the yellow square was blank. The magenta square appeared ok as magenta. The cyan squate appeared sort of purple.

After searching online I was then directed to this web site and to a 'print quality diagnostics page'. This print out is generated from the 'set up' on the front panel of the printer. The print out included the print out of 3 different test patterns...according to the evaluatiuon of the results it suggested all was ok with printheads and alignment.

After this the rest of the analysis didnt really go into potential issues with colour.

Can anyone help please.

Thank you in advance

Hi @Gatehouse,

Welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you.

I understand that you are facing print quality issues with your HP Officejet Pro L7680 All-in-One Printer.

This issue could occur if the printhead is clogged or the electrical contacts on the cartridge or the printhead are not working or the printhead could be defective.

Let's go through a few steps that may help to fix this issue.

And here are a few steps for you in the link: Fixing Print Quality Problems

Let me know how this works.

You have a good day ahead.

I have received several responses.

Including responses from others I have also received responses from 'hp engineeers' telling me to select a 'link' for print relatred problems.

If the people responding had the courtesy to read the email ...all would realise that I have cleary tried all of those steps and am looking for help over and above.

What a complete waste of time
