Abstract
A fluid ejection apparatus is disclosed. One apparatus includes a first head chip and a second head chip. The first head chip includes nozzle groups A1, A2, B1 and C. The second head chip includes nozzle groups D2, E1, E2 and F. The nozzle groups A1, A2, B1, C, D2, E1, E2 and F eject fluid at an average usage rates A1, A2, B1, C, D2, E1, E2 and F, respectively. The average usage rate A2 is smaller than the average usage rate A1. The average usage rate B1 is smaller than the average usage rate A1. The average usage rate C is smaller than the average usage rate A1. The average usage rate D2 is smaller than the average usage rate E2. The average usage rate E1 is smaller than the average usage rate E2. The average usage rate F is smaller than the average usage rate E2.
