Abstract
A printer includes: a platen having an ink-collection slot extending across its width; a wick bar received in the ink-collection slot, wherein an upstream gap and a downstream gap are defined at either side of the wick bar relative to a media feed direction; a printhead positioned over the wick bar; and a vacuum chamber in fluid communication with the ink-collection slot. The wick bar is mounted on a rotatable shaft and the vacuum chamber comprises a scraper positioned for scraping the wick bar as it rotates past the scraper.
