Abstract

A printer including a print media transport path, a plurality of printhead modules located across the print media transport path, each printhead module having an elongate printhead, said printheads being slanted and nozzles of respective printheads overlap with nozzles of printheads of neighboring printhead modules, and a dot data generator for providing print data to nozzles such that print data is stochastically ramped from one neighbouring printhead module to a next neighbouring printhead module.

Claims (13)

1. A printer including:

a print media transport path;

a plurality of printhead modules located across the print media transport path, each printhead module having an elongate printhead, said printheads being slanted and nozzles of respective printheads overlap with nozzles of printheads of neighboring printhead modules; and

a dot data generator for providing print data to nozzles such that print data is stochastically ramped from one neighbouring printhead module to a next neighbouring printhead module.

2. A printer according to claim 1 , wherein the respective printhead modules are in fluid communication with corresponding ink supply ports of one or more ink reservoirs.

3. A printer according to claim 2 , wherein the one or more ink reservoirs are mounted to a mounting frame.

4. A printer according to claim 3 , wherein the one or more ink reservoirs are located between the mounting frame and the number of printhead modules.

5. A printer according to claim 3 , wherein the one or more ink reservoirs comprises a single elongate ink reservoir.

6. A printer according to claim 3 , further comprising a plurality of ink reservoirs.

7. A printer according to claim 2 , wherein the ink supply ports include ink supply conduits surrounded by protrusions.

8. A printer according to claim 7 , wherein the protrusions are engaged by elastomeric collars formed in the printhead modules.

9. A printer according to claim 2 , wherein the printhead modules are identical.

10. A modular printhead according to claim 1 , wherein the printhead modules are all slanted in the same direction.
