Thank you for your question, my name is ***** ***** I look forward to assisting you.

Please note, a rating is only needed when we are finished.

Can you please remove the power to the printer (so unplug it from the power socket).

Then wait 10 minutes, connect the power again to the printer, turn it on and tell me please if it is now operating correctly.

Can you remove the ink from the printer then power it off.

then using a Q-Tip with cleaning alcohol (or warm water if you do not have any), clean out the areas where the ink goes in.

Then use a damp cloth and wipe down the inside of the printer.

Once done, let it dry for 10 minutes

Then put the ink back in, power it on and tell me if it then prints correctly please

Unnecessary. The interior of the printer and printer heads clean

Even though they are new cartridges, they may be faulty, have you tried different cartridges?
