My HP 7640 printer doesn't print the color cyan

[badmac000]

My HP 7640 printer has started printing paged with a reddish or pinkish color. I went to "printer maintenance and performed a "clean cartridges" option. The resulting printed page showed no Cyan color. Any ideas on how I might fix this?

Hi @badmac000,

Welcome to the HP Support Community.

Thank you for posting your query, I will be glad to assist you.

I see that you are facing an issue with one of the colors missing while printing on your Printer.

A) Please follow the steps below to perform a power drain.

1) Take out the cartridges

2) Unplug the power cord from the printer & wall.

3) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds.

4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector.

5) Insert the cartridges back into the printer.

Remove the cartridges > Unplug the power cord > Wait for 30 seconds > Plug the power cord back in > Insert the cartridges

B) Kindly refer to the steps on this link to update the printer firmware and let me know if that resolves the issue.

C) If the issue still persists, refer to the steps on this link to further troubleshoot.
