The second link suggest downloading a service tool.
This is how to reset the ink counter, but take care about the version number.
Only versions dated after the release of the PRO-300 are susceptible to work.
Others will block all further access.
FYI: this is (an evaluation copy of) version 5103 from 2018
The version for the PRO-10 already had number ST5204, I wouldn't dare.
You will have to pay a few bucks for a reliable hack.
Search on eBay, I've seen version 6000 (no guarantee but much more chance).
Do your research, good luck and report back.
PS: the ink absorbers will not overflow the next day, this is something to tackle later.
