Need Help Roland VS540i, Brand New Printhead Zero Nozzles firing after installing

It doesn't look melted to me, it just looks like the contacts have been folded back with the white plastic backing (but still needs replacement)... Take care when connecting these multiple times, they are fairly delicate. Make sure when fitting, it's perfectly straight/flat, if anything try to slightly angle the metal contact side down when fitting (not by much, 5-10 degrees or so) when inserting (imagine the metal touching the contacts inside the connector first). That way less chance of peeling back. Hope that makes sense!

Thank you for your response. I have had a look at the contacts and I tried to use tweezers to peel them back up but I think it may have actually melted as I couldn't unfold it. From my posts above showing my steps and what I have replaced so far does it sound like the Ribbon cable may be the issue? (no ink at all is coming through) I had noticed that the ribbon cable had this slight defect but it looked like that when I removed the old printhead so I assumed it must have been working. Also I thought I read somewhere that each ribbon cable only affects one colour not all. These are the reasons why I didn't change them early on. What is your advice.

Also thank you for the tips. It has been a nightmare constantly connecting and reconnecting these multiple times as I have been testing different printheads. I have been connecting a corner first then the other corner but I know this is wrong so will do it the way you describe.

Thank you
