Printer including dot data generator with stochastically ramped print data
View Patent ↗A printer including a plurality of printhead modules located across a print media transport path is disclosed. Each printhead module has an elongate printhead. Nozzles of respective printheads overlap with nozzles of printheads of neighboring printhead modules. The printer further includes a dot data generator for providing print data to nozzles such that print data is stochastically ramped from one neighboring printhead module to a next neighboring printhead module.
1. A printer including:
a plurality of printhead modules located across a print media transport path, each printhead module having an elongate printhead, nozzles of respective printheads overlap with nozzles of printheads of neighboring printhead modules; and
a dot data generator for providing print data to the nozzles such that print data is stochastically ramped from one neighbouring printhead module to a next neighbouring printhead module in an overlap region.
2. A printer according to claim 1 , wherein the printheads are slanted.
3. A printer according to claim 2 , wherein the printhead modules are all slanted in the same direction.
4. A printer according to claim 1 , wherein respective printhead modules are in fluid communication with corresponding ink supply ports of one or more ink reservoirs, the ink supply ports including ink supply conduits surrounded by protrusions.
5. A printer according to claim 4 , wherein the protrusions are engaged by elastomeric collars formed in the printhead modules.
6. A printer according to claim 1 , wherein the printhead modules are identical.
