hello alif, it think it is better to change the language first and go from there. On the main print card you have a switch CHK (or RS7) put it on 4, switch on the contact. the display changed to an 8 digit number, change the last (most to the right) with the + or - on the display to 0 (now it's on 1). After changing put CHK (or RS7) back to zero.
Kind regards
Marcb
