I found it interesting that it continued for only 1 minute. At the same time, I found it interesting that you removed the printhead while the printer was off. The only times I have ever changed a head is when the printer tells me to, so I go through the procedure of changing it while the printer is on. It starts with all the ink being dumped, then it tells you to remove it, then you put a new one in, then it fills with ink for about 10-15 mins and hopefully all is good.
I'm sure the printer knew it was a different head since they have serial numbers that the printer than read, but the way you changed it sounds a bit out of sequence to me. What is also odd is that after only 1 minute it came up with an error. If it initially accepted the head, it should take 10-15 mins to fill with ink, unless of course what you did was somehow bypass the whole ink dumping and refilling procedure, but this might also explain why it didn't want to initialize the new head.
Now you got a problem I guess because you don't really know if the new head is faulty, since you didn't seem to change it as per procedure, or if you have a bad main board. It can only be 3 things. Main board, carriage (which has a circuit board in it as well), or printhead. I had all 3 replaced on my machine, so I know how one can fry the other and all that stuff, but these 3 things together basically is the entire guts of the printer from the brains point of view.
Sorry I have no advice, and I'm not even sure if going through the correct procedure would help now that the new head has already been put into the printer and hence "tainted".
