Why “Service required” returns soon after reset?
Heavy cleaning or intensive printing quickly raises the counter.
Will an external tank help?
It can delay saturation in heavy-duty use; optional, not mandatory.
Can I downgrade firmware to reset?
Not necessary — WicReset works at the service counter level.
Do trial keys fully unlock?
No — they reduce the counter partially (80–90%).
