PX-K150 questions
Is this the Epson PX-K150 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 PX-K150'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.
