E-Sudio 18 language change problem

[eyuperol]

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.

Thanks. While the machine was in service mode, I successfully completed the language change process by trial and error by entering the numbers I last tried in test mode D. The code to be entered to change the language is 220. After entering this code, if you select 0 from the menu that appears, it becomes English, if you select 10, it becomes Turkish. While I was in that menu, I selected 6, so the language of the machine became Chinese. Since it is toner refill, I have to log in with the method I first explained. How can I permanently bypass the toner warning? By the way, after I found this solution, I searched the net a little and reached a PDF containing the test mode codes of another model (e-STUDIO350/450), I am sharing the video of how I reached the solution, maybe it will help others.
