Title:
プリント媒体真空プラテンシステム
Document Type and Number:
Japanese Patent JP3748782
Kind Code:
B2
Abstract:
An ink-jet apparatus employs a platen having an array of vacuum ports that are each filtered. The filter is constructed to provide restricted-airflow rates which remain uniform when the platen is either fully covered or partially uncovered. The filter mechanism provides both airflow restrictions such that ink drop flight trajectories in the printing zone are unaffected, acoustic dampening of the vacuum pump is provided, and vacuum pressure is kept relatively high proximate the print media edges.
