We are trying to upgrade the firmware of our printer Xerox WC 5845 via altboot to the version 072.190.004.09101 (current version is/was 071.190.103.05401) and the installation got stuck in "scan engine" for hours (as you can see in the picture). We had to turn off the printer after 1 day, now it doesn't start up and if we try to update again it gets stuck at the same point. What can we do to make the printer work again??
Thanks in advance,
