It's common in DTG ownership.
If a DTG printer is going to print well, it needs volume from day 1. Most DTG printers put the horse before the carriage and buy the printer before they have volume. That's why printers fail. Not the hardware but the lack of orders.
Print 24 shirts a day, every day, from day 1, and it won't give you so many headaches.
The Veloci-Jet is a fine piece of hardware and I have a few competitors who now have million dollar print businesses starting with that brand machine.
