Elongate printhead assembly
View Patent ↗The present invention relates to an elongate print head assembly. The print head assembly includes an elongate spine defining a plurality of chambers for carrying respective types of ink. The print head assembly also includes a plurality of adjacent print head modules attached to the spine along its length. Each print head module has a plurality of nozzles which, in turn, are each in fluid communication with a respective chamber. The print head modules combine to form a plurality of rows of nozzles along the length of the print head assembly such that, in use, each row expels a respective type of ink.
1. An elongate print head assembly including:
an elongate spine defining a plurality of chambers for carrying respective types of ink; and
a plurality of adjacent print head modules attached to the spine along its length, each print head module having a plurality of nozzles each in fluid communication with a respective chamber;
two end caps for attaching to the spine so as to hold the plurality of adjacent print head modules together;
wherein the print head modules combine to form a plurality of rows of nozzles along the length of the print head assembly, each row for expelling a respective type of ink.
2. An assembly according to claim 1 , wherein an actuator includes a flexible PCB extending along the length of the print head assembly.
3. An assembly according to claim 2 , wherein the flexible PCB includes a plurality of control circuits for controlling each respective print head module.
4. An assembly according to claim 3 , wherein each print head module includes an actuator for actuating the nozzles in the print head module.
5. An assembly according to claim 1 , wherein the spine includes a strengthening member extending along its length.
