value of the life expectancy. For instance, the remaining value of fuser unit is calculated,

The value = 100 x (1 – the number of sheets printed with the current fuser unit/31000)

KX-P8420 has a system by which prevents the Imaging unit and the fuser unit of another Panasonic product

(ex.KX-P8410) or other printers which use the same engine (ex.Phaser560) from being used with KX-P8420.

The Imaging unit and the fuser of each product has a unique ID number stored inside. KX-P8420 checks these ID

numbers. Then it shows error message and does not allow them to be used with if the ID number is not correct.

In addition, the ID number of the KX-P8420 Imaging unit is different between the one for America and the one for

other regions. So for example, the Imaging unit shipped to the U.S.A cannot be used with KX-P8420 shipped to

Europe.
