  Thanks John, You saved me alot of time and frustration dealing with that idiot I was talking with at Ebson, he didn't know sh$t about my printer, he began by telling me that my printer was like a human body and I was like WTF???, well anyway I eventually told him he was stupid and hung up on him, I called the place where I purchased my printer from and he gave me your website, everything is working fine now and you saved me from any down time I would have had taking to the service center!...thank you again!

  I am very, very grateful that this helped me in resetting the school printer. it is very hassle (avoiding corona virus spread) in my part to carry the printer from my place transporting via boat to the city (travelling for at least an hour by the sea) but with your help it solved my problem we can now continue the printing of the modules and self learning materials of the children since the classes will start on October 5. good job!
