Mike. Thanks for sharing that you don't speak Portuguese.
"Hello everyone, my machine has stopped heating but there is no error on the panel, the drying fans have also stopped can you help me the equipment is a mimaki jv3 160"
Robson, Verifique todos os fusíveis do painel de alimentação até o painel que controla o aquecedor e os ventiladores.
Caso contrário, verifique os cabos etc.
Everyone else...
Check the fuses on the powerboard to the board that controls the heater and fans.
Failing that, check the cables etc.
