LIQUID EJECTION HEAD PRODUCTION METHOD AND LIQUID EJECTION HEAD PRODUCTION SYSTEM

摘要

The production method for a liquid ejection head is provided, in which a first head module is set, a second candidate head module is selected, a first representative value of the first head module is acquired, a second representative value of the second candidate head module is acquired, an average value of the first representative value and the second representative value is derived, and the second candidate head module by which the derived average value is 0.76-fold or more and 1.24-fold or less of an average ejection volume target value is set as a second head module.

主权项

1. A production method for a liquid ejection head having a structure in which a plurality of head modules are arranged along a single direction, each of the plurality of head modules including a plurality of ejection elements,
the liquid ejection head production method comprising: a first head module setting step of setting a first head module; a second candidate head module selection step of selecting a second candidate head module, the second candidate head module being a candidate for a second head module, the second head module being arranged at a position that is adjacent to the first head module; a first representative value acquisition step of acquiring a first representative value, the first representative value being a representative value of ejection volumes of ejection elements that are included in the first head module and that are arranged at a joint part between the first head module and the second head module; a second representative value acquisition step of acquiring a second representative value, the second representative value being a representative value of ejection volumes of ejection elements that are included in the second candidate head module and that are arranged at the joint part; an average value derivation step of deriving an average value of the first representative value and the second representative value; and a setting step of setting, as the second head module, the second candidate head module by which the average value derived in the average value derivation step is 0.76-fold or more and 1.24-fold or less of an average ejection volume target value, the average ejection volume target value being a previously decided target value of an average ejection volume in a whole of the head module.
