Not printing Magenta on Diagnostic Page or any where

[DEEP2021]

Just bought a new HP DeskJet Ink Advantage 3835 All-in-One Multi-function Printer it's not printing Magenta on the Print Quality Diagonostic Page.
Colour prints are coming out weird also. As there is no presence of Magenta I suppose. 

What should I suppose to do?

A quick reply will be really helpful.

Hey there! @DEEP2021, 

Welcome to the HP forums!  

I understand that your printer is not printing magenta color on the diagnostics page.

Align the ink cartridges for the best print quality.
Lift the scanner lid.
Place the alignment page with the print side down on the scanner glass, and then position it according to the engraved guides around the glass.
Close the scanner lid.
Touch OK to scan the page and complete the ink cartridge alignment.

Clean the ink cartridges using the HP software, and then evaluate the results.

To avoid issues that require cleaning, always turn the printer off with the Power button.

Load plains paper into the input tray.
On the printer control panel, swipe the display to the left, and then touch Setup.
Touch Tools, and then touch Clean Cartridges.
The printer performs the automated cleaning process and then prints a Print Quality Diagnostic page.
If the print quality is acceptable, you can stop troubleshooting.
If the print quality is unacceptable, touch OK for a Second-level Cleaning when prompted to continue the next level of cleaning.
If the ink cartridge nozzles are badly clogged, it might require another cleaning cycle. If so, wait 30 minutes before you perform both levels of cleaning again.

Please refer the document to further troubleshoot print quality issues: http://support.hp.com/us-en/product/HP-DeskJet-Ink-Advantage-3830-All-in-One-Printer-series/7172328/...

Take care,            

Have a wonderful day ahead! 🙂
