вот похожее проблема с Samsung ml1861 и рекомендации от Алексея по его восстановлению! надеюсь такое решение будет для восстановления 1670 !
1. Входим pROBE>
2. Нажимаем Ctrl+C
"Do you want to download from external port?[N] :"
Нажимаем Y
"Enter Start Address[0x40017000] : 0x"
Нажимаем Enter
3. Перетаскиваем файл Kernel_ML1861_V1.03.00.25.hd на usbprns2.exe
Снова спросит:
"Do you want to download from external port?[N] :"
Нажимаем N
4. Вводим команду go 40017000 и нажимаем Enter
Принтер должен включиться в обычном режиме, но это еще не все
5. Не выключая принтер прошиваем оригинальной прошивкой ML1861_V1.03.00.25.hd
Файлы здесь http://rghost.ru/48720847 (http://rghost.ru/48720847) или здесь http://yadi.sk/d/BQPKJgfI9C9xZ (http://yadi.sk/d/BQPKJgfI9C9xZ)
