If your machine is telling you "Open window and check printhead cover is properly closed," the most likely cause is the upper frame on the ink tube system is cracked or broken. The printhead cover on the carriage locks into the lower latch in the ink tube system. If the lower latch is compromised, the machine will not function.
Watch the video tutorial for the repair procedure here.
If your ink tube system is leaking, or otherwise broken beyond repair, you can find the replacement ink tube systems here:
