Evidence boundary: PrintRig has not physically tested every machine. We compare published manufacturer documentation and business economics; request a live sample workflow and written support terms.
Ask for the flow diagram
Determine whether the system circulates the tank, line, damper path or another portion of the ink system. A product page that merely says “white-ink circulation” does not describe how much of the risk is managed.
Circulation does not remove maintenance
No circulation claim eliminates nozzle checks, scheduled cleaning, controlled environment, correct shutdown/standby procedure or consumable replacement.
- Daily startup and shutdown steps
- Maximum unattended/idle interval
- Agitation/circulation timing while idle
- Approved ink and cleaning fluids
- Clog-support and printhead-warranty exclusions
Price downtime
Use a failed-production allowance in the calculator. Maintenance time and reprints belong in cost per saleable transfer even when ink use looks low.
NEXT DECISION
Run the economics before asking for financing.
Build a saleable-transfer cost with the cost-per-print calculator, then pressure-test the capital with the break-even model.
