[Note]
●Above calculations are an estimate based on ambient temperature of 20°C
●Ink quantity for periodic replacement is a case when the operating hours is more than 200 hours.
★In case the operating hour is less than 200 hours, please use following formula to calculate the ink quantity for periodic replacement.
200 (hour/month)
Ink quantity for periodic replacement ＝ Ink quantity per replacement (cm3/replacement) ×
Ink life (hours)
〈Example〉65 ∝m nozzle,
Ink quantity used by printing
＝1 ＋ 3 ＝〔8.3×10－（7 cm3／dot）×15（dots／character）×8（characters／pcs）×6×10（6 pcs／month）〕
＋ 400（cm3）×
16hours／day×25（days／month）
1，200hours
Makeup ink consumption by Evaporation
≒598（cm3／month）＋134（cm3／month）≒ 732（cm3／month）
＝2 ＋（Ink quantity for printhead cleaning）
＝5（cm3／hour）× 16（hours／day）× 25（days／month）＋（Ink quantity for printhead cleaning）
＝2,000（cm3／month）＋（Ink quantity for printhead cleaning）
