Hello, I have a question about printheads for Océ Arizona 550GT. Head manufacturer is Toshiba, which offers only Toshibatec CE2. I bought this head - it's not installed yet https://www.digiprint-supplies.com/en/arizona-550-460-print-head-assembly.html?category= But it came with the CE4M mark https://www.digiprint-supplies.com/en/toshiba-ce4m-printhead.html the original head is this https://www.digiprint-supplies.com/en/arizona-550-gt-kit-f-s-printhead-ce2-bond-3w3010112660.html Digiprint says he sent me the right head (but has a different name) and I don't know if I should risk installing. And I'm trying to find out if toshiba makes more CE2, CA4, CE4M atc models and everything looks the same. Or if there's really a difference.
