Modular printhead with consecutive printhead modules
View Patent ↗A modular printhead module is disclosed. The printhead module includes a carrier. An elongate ink delivery member is mounted in the carrier and defines a plurality of longitudinal conduits, each for carrying a respective type of ink. The elongate ink delivery member further defines a plurality of sets of apertures, each set including a plurality of apertures which are each in register with a corresponding conduit. A single printhead including a plurality of inkjet nozzles is also provided. Each inkjet nozzle engages with a respective set of apertures so that each inkjet nozzle is engaged in fluid communication with a respective conduit.
1. A modular printhead comprising:
an elongate channel;
a flexible printed circuit board in the elongate channel; and
a plurality of printhead modules received in the elongate channel, each printhead module comprising:
a carrier;
an elongate ink delivery member mounted in the carrier and defining a plurality of longitudinal conduits, each conduit carrying a respective ink, the elongate ink delivery member further defining a plurality of sets of apertures, each set of apertures including a plurality of apertures which are each in register with a corresponding conduit; and
a printhead including a plurality of inkjet nozzles, each inkjet nozzle being in fluid communication with a respective conduit, and a fine pitch flex printed circuit board,
wherein, when each of the printhead modules is received in the elongate channel, the fine pitch flex printed circuit board of each printhead module is arranged to contact the flexible printed circuit board in order to receive data and power from the flexible printed circuit board.
2. The modular printhead as claimed in claim 1 , wherein the apertures of each set are diagonally disposed with respect to a longitudinal axis of the elongate ink delivery member.
3. The modular printhead as claimed in claim 1 , further comprising a capping mechanism arranged on the carrier, the capping mechanism having a cap for capping the respective printheads.
4. The modular printhead as claimed in claim 3 , wherein the capping mechanism further includes a biasing arrangement for biasing the cap into an uncapped position.
5. The modular printhead as claimed in claim 3 , further comprising an actuating mechanism operatively arranged with respect to the carrier and engaged with the capping mechanism for moving the cap between capped and uncapped positions.
6. The modular printhead as claimed in claim 1 , in which the carrier is in the form of a channel member, the printhead modules being positioned in the channel member.
