NX430 questions
Is this the Epson NX430 Adjustment Program?
No. The Adjustment Program is Epson's Windows service software for technicians, one per model, with many service functions. VNIT Reset Tool only reads and resets the NX430's waste ink counters, on Windows and Mac, which is all the ink pad error needs.
The free trial worked. Do I still need a key?
Not straight away. The trial leaves the counter at 80%, so the error comes back sooner than after a full reset to 0% with a key.
