A carriage moving mechanism including a driving unit including a driving pulley, a driving motor, and a first support member for supporting both the driving pulley and the driving motor, a driven unit including a driven pulley and a second support member for supporting the driven pulley, and a third support member supporting both the driving unit and the driven unit, an annular belt that is wound around both the driving pulley and the driven pulley, a first outer peripheral surface and a second outer peripheral surface facing to the first outer peripheral surface, and a first carriage that is attached to the first outer peripheral surface, wherein the second support member, the third support member, and the first support member are aligned in this order in a first axis, and the third support member is disposed inside the annular belt.

A printhead module for a modular pagewide inkjet printhead. The printhead module has only four rows of print chips configured for printing four different inks, each print chip having multiple nozzle rows for redundant monochrome printing of one respective ink. A print zone of the printhead module has a width of less than 100 mm across the four rows of print chips.

Herein is disclosed a method of transfer inkjet printing comprising jetting a radiation curable inkjet ink onto an intermediate transfer member of an inkjet printer to form an image; irradiating the radiation curable inkjet ink on the intermediate transfer member to form an at least partially cured image; and transferring the at least partially cured image to a substrate to form a printed substrate. Herein is also disclosed a transfer inkjet printing apparatus adapted, in use, to perform the method.

A system for treatment of thread includes a weft thread printer having an intake positioned to receive a weft thread from a source, as well as an encoder that is configured to detect a length of the weft thread as the weft thread moves through the weft thread printer along a travel path. The system also includes a printhead positioned to apply coatings of a plurality of colors to the weft thread and yield a treated weft thread, as well as an outlet positioned to pass the treated weft thread to a loom.

In one example method, a determination is made via a processor that a document is to be printed using a printer including a printhead assembly and a printhead accessory based on a received print job. A determination is made via the processor that a first portion of the document is to be printed by the printhead assembly and a second portion is to be printed by the printhead accessory based on a characteristic of the printhead accessory. The first portion of the document is printed via the printhead assembly and the second portion of the document is printed via the printhead accessory.

A recording apparatus includes a recording unit configured to apply a recording agent to a recording medium, the recording agent developing metallic luster when fixed to the recording medium, a conveyance unit configured to come into contact with the recording medium and convey the recording medium, after an image to be recorded on a side where the amount of the recording agent is smaller is recorded on a first side of the recording medium, an image to be recorded on a side where the amount of the recording agent is greater is recorded on a second side of the recording medium opposite from the first side.

An inkjet printing device for multi-color printing includes: multi-color inkjet nozzles that move in the direction perpendicular to the moving direction of the target base printing material and also in the direction parallel to the surface of the target base printing material; plasma ejection ports provided downstream of the multi-color inkjet nozzles in a manner oriented facing the surface of the multiple colored inks printed on the target base printing material; and an electron beam irradiation part located on the downstream side of the inkjet nozzles and plasma ejection ports, in a manner oriented facing the printed surface of the target base printing material.

A liquid discharging device discharges a liquid onto a recording medium for image formation, and includes head modules each including a nozzle array that discharges a liquid of at least one color, the head modules being connected in a direction of the nozzle array from one of the head modules, the one supported by a guide extending in a main-scanning direction; and processing circuitry functioning as an acquirer that acquires image data based on which the image is formed, and an allocator that allocates, to dots of the image data, a row of liquid droplets discharged from one of the head modules closest to the guide in a sub-scanning direction, such that the liquid droplets discharged from the head module closest to the guide are equal to or higher in ratio than the liquid droplets discharged from each head module other than the head module closest to the guide.

A pagewide printhead for printing redundantly in four colors. First and second rows of printhead chips are mounted on a common ink manifold having four ink supply channels for supplying four colors of ink to the first and second rows of printhead chips. Dedicated ink outlets interconnect one ink supply channel of the ink manifold with a pair of redundant nozzle rows in each printhead chip.

An image forming apparatus includes an image forming unit, a conveyance guide having an opening portion, a measurement unit including a light entrance portion, and a moving member including a reference portion. The measuring unit is configured to measure an image on a sheet through the opening portion in a first state where the measurement unit is positioned in a first position and the moving member is positioned in a third position. The measurement unit is configured to measure the reference portion in a second state where the measurement unit is positioned in a second position and the moving member is positioned in a fourth position.
