Abstract
A printer includes a plurality of stationary printhead modules located across a print media transport path. In order to provide continuity of printheads across the transport path some, or all, of the printheads are slanted so that the ends of the printheads overlap. In one embodiment the printhead modules are each inserted into ink reservoirs that are in turn attached to a mounting frame that lies across the print media transport path.
Claims11
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 adapted to be individually removed and replaced;
- wherein printheads of a number of said modules are slanted to allow nozzles of the printheads to overlap with nozzles of printheads of neighboring printhead modules thereby providing continuity of printheads across the print media transport path;
- and
- a dot data generator for providing print data to nozzles of the printhead modules in overlapping ends such that print data is stochastically ramped from one neighbouring printhead module to a next neighbouring printhead module.
