Installed a new ink cartridge, but the print quality is not improved

While i installing the new ink cartridge, i have dislodged the print head from the carrier. I have replace ink cartridge many times but again and again printer shoe poor print quality and make mistakes while printing. I also try another to manage this issue but problem again same as it. Anybody can help me to remove or handle this query. So give recommendation please.
Thanks.

 

Is the new cartridge a genuine or an aftermarket cartridge?

A couple other things to check:
Does the printer have a waste tank?
Is there a cleaning pad that is full of ink and not cleaning the head?
Is the print head part of the ink cartridge?
Did you do a head cleaning and a printhead alignment?
