This sub board assembly is suitable for Mutoh Toucan printers. This is the original Mutoh part (number DF-44163) and it carries a product warranty. IMPORTANT: you need to replace the main board if lower than revision F, the CR head board if lower than revision number B and the CR base board if lower than revision number D when replacing the sub board on Toucan printers due to some engineering changes made on the boards. You do not need to replace the additional boards if the revision number of the board is equal or higher than the above mentionned revision numbers.
