■ ITB Unit Detection (New/Old)
To detect a fuse substrate (UN74) of an ITB cleaning unit when power is turned on or when a right door is closed.
Judgment standard: When the voltage of the fuse board is 0 V (blown fuse condition), it is judged as an old product, and when
the voltage is a specified value, it is judged as a new product.
NOTE:
• When a new product is detected, the part counter/LIFE value is automatically cleared. (ITBCLN-U)
• After the new product is detected, a load voltage is applied to the fuse substrate (UN74), and the fuse is cut off.
