Abstract
An ink jet printer for printing on a substrate comprising a first print head outputting ink and defining an ink meniscus; a platen operable to carry the substrate; a support structure; and a print head mechanism coupled to the support structure and carrying the first print head. The print head mechanism moving the first print head relative to the platen. A controller controls the print head mechanism such that at least one of a predetermined acceleration and predetermined deceleration of the print head mechanism is achieved such that the ink meniscus is operably maintained.
Claims30
An ink jet printer for printing ink on a substrate, the ink jet printer comprising:
- a first print head comprising at least one nozzle for outputting the ink during a printing operation wherein the ink is delivered to the substrate from the first print head;
- a platen operable to carry the substrate;
- a support structure;
- a print head mechanism coupled to the support structure and carrying the first print head, the print head mechanism for moving the first print head relative to the platen;
- and
- a controller for controllably limiting any of the acceleration or deceleration of the print head mechanism any of towards the platen or away from the platen when the platen is moved for an operation other than the printing operation.
A method, comprising the steps of:
- providing an ink jet printer comprising
- a first print head comprising at least one nozzle for outputting ink during a printing operation wherein the ink is delivered to the substrate from the first print head,
- a platen operable to carry a substrate,
- a support structure,
- a print head mechanism coupled to the support structure and carrying the first print head, the print head mechanism for moving the first print head relative to the platen, and
- a controller;
- and
- operating the controller to controllably limit any of acceleration or deceleration of the print head mechanism any of towards the platen or away from the platen when the platen is moved for an operation other than the printing operation.
