International Classification:

B41J 2/165
B41J 25/304
B41J 25/34
B41J 25/00

Abstract:

A print bar assembly includes: a mounting frame having a pair of opposite first and second sidewalls extending parallel to a media feed direction, the first sidewall having an upwardly extending first guide slot defined between opposite first bearing surfaces; a print bar carriage slidably received within the mounting frame and an actuation mechanism operatively connected to the print bar carriage for lifting and lowering the print bar carriage relative to the mounting frame. The print bar carriage includes a chassis, a printhead and a pair of first bearings rotatably received in the first guide slot. During sliding movement of the print bar carriage, the pair of first bearings travel within the first guide slot and bear against the first bearing surfaces to constrain rotational movement of the print bar carriage.

International Classification:

B41J 2/165

Abstract:

A modular printer includes: a media feed path defining a media feed direction and a plurality of printer modules positioned in a staggered overlapping arrangement so as to extend across a width of the media feed path. Each printer module includes a printhead and a respective maintenance sled for slidably moving towards the printhead in a direction parallel to the media feed direction. Further, the maintenance sleds for neighboring printer modules are configured to move in opposite directions towards their respective printheads.

US Classification:

347 29, 347 37

Abstract:

A printer assembly includes: a housing having referencing slots defined in opposite sidewalls; a stop positioned towards a lower end of each referencing slot; a print bar carriage slidably received within the housing; and a lift mechanism for lifting the print bar carriage relative to the housing. The print bar carriage includes: a chassis; a printhead supported by the chassis; and a pair of lugs, each lug being slidably received in a respective referencing slot of the housing. Each stop has a datum surface which defines a printing position of the print bar carriage, the print bar carriage being in the printing position when each lug is in abutting engagement with a respective datum surface.
