Hello Don,

One other fix you can try is accessing the hidden maintenance mode. Try this;

You can enter the menu in this way:

Start up the machine with push in the buttons "online" and "cancel"
--You will see the message "Download mode press online key"
Press about 15 times the "menu" key
--You will see the message "Uncheck consumable mode"
Press about 15 times "menu" and 5 times "enter"
--You will see "Press access key"
Press a few enters
Press 3 times "cancel"
Go to the EDC mode
-- you will see "press access key"
Press "cancel"
Go to maintenance and initialize the parts you like to reset.
