[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.

Ink life (hours)

〈Example〉65 ∝m nozzle, JP-K67 ink, 8 characters/printing, 5 × 7 font, 6M pcs/month, 16 hours/day, 25 days/month operation

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）
