Abstract
A method to control a printer carriage in which the printer carriage is controlled to move along a first axis at a first predetermined speed when a printhead, installed on the printer carriage, is ejecting printing fluid in a print zone. The printer carriage is moveable bidirectionally along the first axis in swaths to enable the printhead to print in the print zone. The printer carriage is also controlled to move along the first axis at a second predetermined speed, higher than the first predetermined speed, when the printhead is not ejecting printing fluid in the print zone.
Claims20
A method to control a printer carriage, the method comprising:
- determining whether a printhead is to eject printing fluid onto a medium in a subsequent swath;
- controlling the medium to move along a second axis at a first predetermined speed in response to a determination that the printhead is to eject printing fluid in the subsequent swath;
- and
- controlling the medium to move along the second axis at a second predetermined speed, higher than the first predetermined speed, in response to a determination that the printhead is not to eject printing fluid in the subsequent swath.
An apparatus comprising:
- a controller;
- and
- a memory on which is stored machine readable instructions that are to cause the controller to:
- determine whether the printhead is to eject printing fluid onto a medium in a subsequent swath;
- control the medium to move along a second axis at a first predetermined speed in response to a determination that the printhead is to eject printing fluid in the subsequent swath;
- and
- control the medium to move along the second axis at a second predetermined speed, higher than the third predetermined speed, in response to a determination that the printhead is not to eject printing fluid in the subsequent swath.
An apparatus comprising:
- a printer carriage to receive a printhead;
- a first actuator to move a medium along a medium axis,
- first circuitry to analyze image data to determine whether a subsequent swath includes a region in which the printhead is to eject printing fluid;
- and
- second circuitry to control a second actuator to control the speed of movement of the medium using the analysis of the first circuitry, wherein the second circuitry is to control the second actuator to move the medium at a first predetermined speed when the printhead is to eject printing fluid in the print zone in the subsequent swath and to move the medium at a second predetermined speed when the printhead is not to eject printing fluid in the print zone in the subsequent swath, wherein the second predetermined speed is higher than the first predetermined speed.
