FIELD: process engineering.
SUBSTANCE: invention relates to fluid release head backup including multiple ink feed ports and lines on backup between adjacent power generating elements. Backup of substrate of fluid release head comprises array of elements generating power for fluid release, first common line, second common line, first separate lines configured to communicate elements and first common line and second separate lines to communicate elements and second common line. Array of elements is arranged between first common line and second common line. First separate lines are arranged between array of elements and first common line. Second separate lines are arranged between array of elements and second common line. Array of elements on the surface is arranged between first common line and second common line. Multiple first separate lines are arranged between array of elements and first common line. Multiple second separate lines are arranged between array of elements and second common line. Multiple fluid feed ports are arranged at least in one of multiple zones between adjacent elements, multiple zones between adjacent first separate lines and multiple zones between adjacent second separate lines.
EFFECT: higher density of power generation elements.
