Strange behavior of the printer + no colors

[ngatet]

Hello, I have bought the printer 6 months ago. Recently, the printer stopped printing in colors. I checked the settings - no grayscale. The printer prints out only in black color. When I want to print the test page, there is only the black colon - not magenta, cyan nor yellow (not a bit of it). I bought another cartridges (genuine) last week, but it didn't help. Still having the same problem and moreover the printer began reporting low level of ink despite the fact that I have bought the cartridges recently and printed about 10 test pages.
Sorry for any mistakes in the text, I am not a native speaker. 🙂

Hey there! @ngatet, Thanks for stopping by HP forums!

I understand you have issues printing in color from your printer.

Don't worry I'd like to help you out.

Did you make any changes to your printer?

Are you able to make a color copy from your printer?

Please try the steps recommended below.

Try cleaning the print heads on your printer and check if it helps.

If you found defects on the Print Quality Diagnostic report, run an automated tool to clean the printhead.
Make sure that plain white U.S. letter or A4 size paper is loaded in the tray.
From the control panel home screen, touch the Settings icon (), and then touch Tools.
Touch the Down Arrow (), and then touch Clean Printhead. The product cleans the printheads and then prints a test page.
Review the print quality on the test page.
If the print quality on the test page is satisfactory, return to the current print job.
If the print quality on the test page is unsatisfactory, perform a secondary cleaning of the printhead.
If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes after the last cleaning stage to start the first stage of the cleaning process over again.
If these steps resolved the issue, there is no need to continue troubleshooting. The following precautions might prevent the issue in the future.
Avoid leaving unprotected ink cartridges out of the printer for an extended period of time.
Always use the Power button to turn off the printer. This protects the ink cartridges from exposure to air.

I'll keep an eye out for your response.  

I hope you have a great day! 🙂
