Yea, that is really amazing. I have a friend who has a Z3100 who also used it lightly. He has had it for about 17 years. He called me in a panic one day saying two of his nozzles didn’t print even after several cleanings. I asked him how old the heads were. He said oh, they were the ones that came with the printer. Of course it was fine when he bought a couple of heads :-).
When you say you purged and reprimed your heads, what is the procedure for that? Would we be able to save an old 70 red head on the z3100? I tried soaking heads in a solution of 1/2 distilled water and 1/2 isopropyl alcohol about 3 times and that made no difference for me. ( I also tried 100% alcohol. )I soaked them about 24 hours making sure not to wet the chip on them.

Was semi-shocked this week when I realized all the heads in my Z3100PS (except MK-R) are *18* years old
Dated 2007!
Ofc it's had very little real use -- the volume of test/diag/exercise plots probably outnumbers real prints by 10 to 1 lol -- but still it's kinda wild.
I purged/reprimed all of these heads last year and they're still holding well at 58~59 grams. The printer sat unused since then (rotten life), so this week I revived it with numerous headclean cycles and diag/exercise plots. Also cleaned up the gunk on the service station (both with and without capping station retracted) and the heads/carriage. Also soaked the nozzles of the PK-LG head again since it's getting a little tired.
PSA: my old notes reminded me about the IQSB Plot in the hidden service menu, which I find is much more useful than the regular Diag Plot. Much larger colour patches are easier to evaluate and kind of a mini exercise plot. And 2 ink densities, basically "full" and "half". Plus some alignment-related info. It doesn't test GE, but that's been kinda useless on the regular diag plot anyhow.
