Diagnos av utskriftskvalitetbvisar CYAN utan färg och print blir rödtonade

[Tilpa]

I have an HP ENVY 7640 printer that does not use the blue color when printing in spite of new printing cartridge. Diagnosing print quality I get a page where the CYAN square is without color. How can this be corrected?

Hi @Tilpa,

Welcome to HP Support Community. 
Thank you for posting your query, I will be glad to help you.

Please follow the steps listed below to reset printing systems and then add the printer.
1. Click the Apple menu, and then click System Preferences.
2. Click Printers & Scanners, Print & Scan, or Print & Fax.
3. Right-click (or Control + click) anywhere inside the Printers window, and then click Reset printing system.
4. Click Reset or OK.
Note: Once you click on reset any other printer added to this computer will also get deleted and needs to be added again.
5. If prompted, type your username and password, and then click OK. The printing system resets.
6. Turn off the printer, wait 5 seconds, and then turn on the printer.
7. Wait until the printer is idle and silent.
8. In the Printers window on the Mac, click the Add button.
9. Select your printer from the list, and then click Add.
It might take a few seconds before your printer displays in the Printers list.

Note: Resetting Printing System will delete the drivers of the other printers added to the Mac computer and you may need to re-add those printers.

I hope this helps.
Take care and have a good day.

Unfortunately the information did not help. At the first attempt there was partial improvement to Cyan. Hoping that repeating the steps would improve it further I did this. The result then got me back to scratch again and further tries have not led to any improvement. Thanks for the info all the same.
