The belt unit was damaged at 42% used. It was replaced. I don’t see the reset option in the menu. How do I reset the count in this case?
Hi Dar
There is a note attached to the guide that states that “Only the parts counters that need to be reset appear in the menu.” I assume that means that if the life isnt reached you can use that guide to reset that count.
I suggest that you ring you brother service team and they may have another reset for your case.
I found that if I went through the menu to the parts list and the pressed 3 & 9 it appeared
Thank you for the only correct answer to the Drum reset issue I found.
Brother Customer Service should put you on their payroll.
