I inadvertantly changed the printer control panel language to German and can't figure out how to get it back. My control panel does not have arrows and clicking the settings icon (gear) does not bring up an option for resetting the language. I've tried the procedure described in another posting " Simultaneously press and hold the left arrow button and the Cancel
button. Keep these buttons depressed as you turn the printer on." However it's not clear. What left arrow? My control panel does not have one so I tried the keyboard left arrow. Also I assume the cancel button is the X that I have on my control panel.

Correct instructions for your unit should be as follows: press and hold the cancel (X) button for about 50 seconds until the green led illuminates and then release.

Doesn't work. I have to start a print job for the cancel button X to appear on the control panel. I then immediately press and hold the cancel button for 60 minutes. The printer does nothing. No reset window of any kind.
