HP70 MK/R printheads
« on: June 29, 2026, 06:23:17 am »

I was going through the load of stuff that I received when I bought my HPZ300 and found a two HP70 MK/R Printheads. I don't know why they were in there and I understand that you cannot use the HP70 MK/R in the HPZ3200 and that you need with HP73 with the chromatic red. I have a couple of HP73 printheads so these are not very useful to me but I thought I would just check in to see if anyone knew differently.

That's correct they're not interchangeable, sadly.

I think sometimes ppl buy them before they realize that. The Z3200 I rescued also came with an HP70 MK-R in the box (an after-market one actually).

HP 70 MK-R heads (and R ink) are the only thing keeping Z3100s alive today (without going after-market). They're crazy scarce so sell quickly.

If sealed I'd buy them, but I already mothballed my Z3100 a month ago after the formatter drive dried (and that was after the carriage PCA was replaced and 5 fried heads). I'm also having ink delivery issues with my last 3 MK-R heads, so figure it's just a money pit at this point. (I have a theory that it needs the carriage ink port valves replaced since they are leaking, and the heads are probably fine...) Anyhow I'm putting everything into the Z3200 now for the little bit of printing I do. It was always intended to replace my Z3100 anyhow.

Sorry to hear about the Z3100.
If someone want these HP70 MK/R head please PM me.  They are not in sealed packages and it is likely that they will need to be recovered. I am currently in Switzerland will be back in the US after 7/22. If you pay the shipping (and any import duty) and you can have them for free.
If you are in the US I can ship them when I get back.

Be sure to keep the orange caps on them when not installed, so the ink doesn't dry out and clog them. I put them in a ziplock bag too when keeping them as used spares.
