Has anyone tried to vote with an optically scanned ballot using fountain pen ink? It seems appropriate to use the darkest bulletproof ink for such an occasion. It seems like it should work and be scanned but maybe not.

Perhaps someone has technical knowledge and can say if the scanners will detect fountain pen ink or not.

I imagine officials would say it's ok

I used bulletproof black to vote on an absentee ballot, the only problem was that since migrating to fps my scrawly signature has gained some character and readability, which prompted a letter from the county election officials wondering if I was who I said I was because my signature didn't match the one on file. I just had to send them proof that it had changed and everything was fine. From what I understand, the ink only has to be black, maybe even blue for the scanners to pick it up.

Not in Oz.

Pencil only, by Federal Law. And they provide the pencil.

Bulletproof black is fine on California vote-by-mail (VBM) ballots.
You are filling in dots with numbers to vote yes or no on a multitude
of ballot propositions (referenda) OR for a candidate, so you need
the sample ballot book that came with the VBM ballot to find the
correct dot.

And, in California, the vote-by-mail ballots must have arrived
at the County Recorder's office ON or before election day.
They don't attempt to read postmarks in California; the ballot
is there on time, or it is not counted. If you didn't mail it in.
or you want to save the postage, you fill in everything on the
envelope, omitting the stamp and drop it in the ballot box at
any polling place in your county. They deliver it to the recorder
in its envelope, along with the precinct ballots after the polls close.
