Abstract: A printer includes: an inkjet printhead having first and second rows of printhead chips; a platen having first and second spittoon slots corresponding to the first and second rows of printhead chips, each spittoon slot having a length corresponding to a length of the printhead and a width extending between a respective upstream sidewall and a respective downstream sidewall of the platen; first and second rollers positioned in the respective first and second spittoon slots for receiving ink spitted from the first and second rows of printhead chips; a rotation mechanism for rotating the first and second rollers; and first and second scrapers engaged with respective first and second rollers. A diameter of each roller is less than the width of its respective spittoon slot.

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 absent from a mid-portion of the platen and the mid-portion of the platen is aligned, in the media feed direction, with an upstream media picker.

Abstract: A printer includes: a printhead; a platen positioned below the printhead for supporting print media conveyed along a media feed direction through a print zone, the platen defining a particle-collection slot upstream of the print zone relative to the media feed direction; and a vacuum chamber in fluid communication with the particle-collection slot. An upper surface of the platen has a plurality of raised ribs extending along the platen in the media feed direction and a dam wall extending across the platen transverse to the ribs. The dam wall is positioned at a downstream side of the particle-collection slot and the ribs extend towards the dam wall from an upstream side of the particle-collection slot.

Abstract: A printer includes: a first fixed printhead; a second fixed printhead positioned downstream of the first printhead relative to a media feed direction; a platen for supporting print media; an input media transport mechanism positioned upstream of the first printhead, the input media transport mechanism exerting a gripping force N1 on print media; an output media transport mechanism positioned downstream of the second printhead, the output media transport mechanism exerting a gripping force N2 on print media; and an intermediary media transport mechanism positioned between the first and second printheads, the intermediary media transport mechanism exerting a gripping force N3 on print media. The gripping forces satisfy the relationship N1>N2>N3 for optimal printing results.

Abstract: A printer includes: an inkjet printhead having a row of printhead chips; a platen having a spittoon slot, the spittoon slot having a length corresponding to a length of the printhead and a width extending between an upstream sidewall and a downstream sidewall of the platen; a roller positioned in the spittoon slot between the upstream and downstream sidewalls for receiving ink spitted from the printhead, a rotation mechanism for rotating the roller; and a scraper positioned for scraping received ink from the roller. A diameter of the roller is less than the width of the spittoon slot, and an upper roller surface is relatively closer to the printhead than an upper surface of the upstream sidewall and/or the downstream sidewall.

Abstract: A printing unit includes: three elongate printheads positioned in a staggered overlapping arrangement for spanning across a media feed path, wherein a first printhead and a second printhead are longitudinally spaced apart and positioned in a row across the media feed path and a third printhead is offset from and overlaps with both the first and second printheads; three wipers for longitudinally wiping respective printheads in a direction perpendicular to a media feed direction, each wiper being parked at one longitudinal end of its respective printhead. One of the wipers, in its parked position, is positioned in a space between the first and second printheads.
