My ET16650 stopped printing, I tried cleaning the head numerous times and tried flushing it which did not seem to do anything. I took it to a local repair guy who could not get it to work. Sending the printer to a service centre is quite expensive. The repair person suggested I could remove the printhead and send it to the service centre (or replace it). Problem is I don't know how to remove it. the screws I took out did nothing except to disconnect the tubes. Any help would be appreciated. I am not a knowledgeable computer person. I bought this for a non-profit group and I don't have a lot of money to spend on it.
