Abstract
An inkjet printer detects vibrations within the printer and compensates for the detected vibrations by adjusting a gap between the printheads and the media transport. Additionally, the inkjet printer detects media sheet heights that may cause damage as they pass through the print zone of the printer and adjusts the gap to enable the media sheets to pass through the print zone without contacting the printheads. A method of operating an inkjet printer so configured is also disclosed.
Claims20
A method for operating an inkjet printer comprising:
- receiving print job parameters for a print job with a controller;
- setting a printhead/media gap distance between at least one printhead and a media transport path in the printer using a media type identified in the print job parameters;
- detecting a vibration in the inkjet printer;
- and
- compensating for the detected vibration by adjusting the printhead/media gap distance.
2 more elements
An inkjet printer comprising:
- at least one printhead carrier plate;
- at least one printhead mounted to the at least one printhead carrier plate;
- a media transport path that is configured to carry media past the at least one printhead for printing ink images on the media;
- at least one actuator being mounted to the at least one printhead carrier plate, the at least one actuator being configured to move the at least one printhead carrier plate with respect to the media transport path in a direction that is perpendicular to a plane in the media transport path;
- and
- a controller operatively connected to the at least one actuator, the controller being configured to:
- receive print job parameters for a print job;
- operate the at least one actuator to set a distance between the at least one printhead and the media transport path in the printer using a media type identified in the print job parameters;
- detect a vibration in the inkjet printer;
- and
- compensate for the detected vibration by operating the at least one actuator to adjust the distance between the at least one printhead and the media transport path.
