Detection of Whether the Fixing Unit is New

The machine detects whether the Fixing Unit is new in order to clear the parts counter.

Control description

With this machine, the Fixing Fuse PCB (UN31) detects whether the Fixing Unit is new.

Installing a new Fixing Unit in the machine blows the fuse.

When a new unit is detected, the part counter (COPIER > COUNTER > DRBL-1 > FX-UNIT) is cleared.

When a new Fixing Unit is installed after an error occurs and it is recognized as new, the error is automatically cleared.
