Hello, I have an e-studio 18 printer. This printer was giving a toner error. I turn on the machine by holding down the red (clean / stop) button while the printer is off. It enters service mode. Here I press the up - left - down - right arrow keys in order and enter the setting mode (select the first one in the row) and press the OK button. I come across test mode A. While here, I was bypassing the toner problem by opening the toner cover, pressing the menu button while the cover was open and then closing the cover. Somehow, in this mode, I changed the language of my printer (Chinese, Korean) to a language I don't know which one it is. How can I make this Turkish or English? I will post a link to the image of my printer. There are no numeric keys on it. How can we provide a solution with the code in test mode? When this device is turned on, when I press the menu button, the device goes into test mode A, that is, I do not see a menu as written in the booklet. Therefore, we need to make a change with the code.
