LIQUID EJECTION HEAD, LIQUID EJECTION HEAD PRODUCTION METHOD AND LIQUID EJECTION HEAD PRODUCTION SYSTEM

摘要

The liquid ejection head has a structure in which three or more head modules including a plurality of ejection elements are arranged along a single direction, and the liquid ejection head includes a first head module, a second head module and a third head module which are arranged in ascending order of slope of ejection volume distribution in the single direction or are arranged in descending order of the slope of the ejection volume distribution in the single direction, the slope of the ejection volume distribution in the single direction being evaluated by subtracting an ejection volume at one end part in the single direction from an ejection volume at the other end part in the single direction.

主权项

1. A liquid ejection head having a structure in which three or more head modules are arranged along a single direction, each of the three or more head modules including a plurality of ejection elements,
the liquid ejection head comprising: a first head module; a second head module that has a joint part with the first head module on one end side in the single direction, the second head module being arranged at an arrangement position that is adjacent to other end side of the first head module in the single direction; and a third head module that has a joint part with the second head module on one end side in the single direction, the third head module being arranged at an arrangement position that is adjacent to other end side of the second head module in the single direction, the first head module, the second head module and the third head module being arranged in ascending order of slope of ejection volume distribution in the single direction or being arranged in descending order of the slope of the ejection volume distribution in the single direction, the slope of the ejection volume distribution in the single direction being evaluated by subtracting an ejection volume at one end part in the single direction from an ejection volume at the other end part in the single direction.
