Guys i need to purchase a second hand A4 duplicator for my small business. I see online some machines, can you give me a recommendation which of these three models (Riso, Duplo and Ricoh) can give a less maintenance machine. And give me some idea how much will be the master and ink. I'm a copier technician maybe and hopefully i can trouble shoot a minor trouble when it comes to Duplicators.
Thanks in advance...
