An additive manufacturing machine () comprising a build material spreading system (). The spreading system () has a moveable spreader () with an exterior surface () to spread build material. The spreading system () also has a heater () located separate from the spreader (). The heater () has a heat dissipater () extending around the spreader () to retain, between the dissipater () and the spreader (), air () heated by the dissipater ().

Additive manufacturing spreader with a heater

In one example, a printing fluid delivery system for a printer is described. The printing fluid delivery system includes a plurality of interconnected printing fluid supply modules forming a page-wide printing fluid manifold to supply printing fluid from one or more cartridges to one or more printheads along a print bar in a printer.

Printing fluid delivery system for printers

It is hereby disclosed a carriage arrangement, in particular, a carriage arrangement suitable for a printing system comprising: a carriage; a carriage beam; and a drive mechanism; wherein the carriage is to move along a longitudinal direction of the carriage beam upon action by the drive mechanism and wherein the carriage arrangement comprises a beam compensation mechanism to exert a variable compensating force on the carriage beam, the variable compensating force depending on a deformation amount of the carriage beam.

Printer carriage arrangements

A media transfer system comprising a media drive component and a vent. The media drive component supports and transfers a media in a drive direction. The vent directs air flow towards the leading edge of the media in the drive direction to exert a separating force on the leading edge of the media, the separating force acting on the media away from the media drive component.

Media transfer

A method of feeding a print medium comprises receiving a print medium by a media advance system; transporting the print medium by the media advance system to a print zone wherein the transporting comprises applying a first normal force when the print medium is at a first position of the media advance system and applying a second normal force when the print medium is at a second position of the media advance system, wherein the second normal force is different from the first normal force.

Feeding a print medium and printer

A connection arrangement is between first and second members pivoted together between open and lockable positions. The first member has a first connector and the second member has a second connector, said connectors being adapted to connect by linear movement between them. The first member has a user-actuatable handle adapted, when the first and second members are in said lockable position: during a first movement of the handle, to engage a latch member of the first member with a catch on the second member; and, during a second movement, to move the first and second connectors with respect to one another in a first linear direction between a disengaged and an engaged position of the connectors. A block element on the first member is arranged to prevent said first and second movements of the handle when said first and second members are not in said lockable position. A block-unlock element on the second member is arranged to displace the block element to enable said first and second movements of the handle when the first and second members are moved from said open position to said lockable position.

Connection arrangements

A media-sheet stacking system for stacking media sheets on a device output tray comprises a kicker to advance a media sheet along the output tray by pushing a trailing edge of the media sheet as it exits the device, and a movable element arranged to face the output tray across a space that receives media sheets exiting the device. A drive mechanism is provided to drive the movable element in the direction of advance of the media sheet along the output tray.

Media-sheet stacking systems

A printhead includes a printhead housing and a handle. The handle is movably coupled to the printhead housing. The handle rotatably moves with respect to the printhead housing between a folded position and the non-folded position. In the folded position, the handle extends along a respective housing surface of the printhead housing. In the non-folded position, the handle extends outward from the respective housing surface of the printhead housing.

Handle of a printhead movable between a folded position and a non-folded position

Provided is a print bar. The print bar comprises a reference element to align the print bar with a mounting structure of a printer. The print bar further comprises a flat elongate sheet metal portion with constant height whose length is larger than its width and whose width is larger than its height. Moreover, the print bar comprises a plurality of plastic members detachably mounted to a mounting surface of the flat elongate sheet metal portion. The plurality of plastic members is spaced apart from each other in the length direction.

Print bar

There is disclosed a driver including an elongate shaft and at least one drive assembly. The drive assembly includes a housing which has an orifice for receiving the elongate shaft, and a drive wheel which is located at least partially within the housing. The drive wheel has a bore with a cross-section shaped so that the internal surface of the bore contacts the circumference of elongate shaft when the elongate shaft is inserted into the bore. The bore has at least two fulcrum surfaces so that the drive wheel is pivotable about the elongate shaft. The housing is slideable relative to the elongate shaft.

Drivers

In one example, a holder for a media roll includes a first support to support a first end of the roll, a second support to support a second end of the roll, and a shifter to change the distance between the first support and the first end of the roll without changing the distance between the second support and the second end of the roll.

Media roll holder

A spittoon system for a printing mechanism includes a reservoir elongated in a longitudinal direction and having a bottom part. The reservoir receives printing fluid residue spit from a print-head onto a first zone of the reservoir. The spittoon system further includes a cleaning element arranged inside the reservoir to transfer, by sliding along the longitudinal direction of the reservoir, the received printing fluid residue from the first zone to a second zone. The second zone includes a drain outlet to drain the printing fluid residue from the reservoir.

Spittoon system, printer and method for a printing mechanism

A handoff mechanism for use with a media stacker of a media production apparatus comprises a plurality of kicker units () arranged across a width of the handoff mechanism. A common drive mechanism () is provided to move the plurality of kicker units () between a closed position and an open position. Each kicker unit (), when in the closed position during use, applies a pressure to any media sheets that are already stacked in a stacker tray () while a new media sheet is being fed to the stacker tray. The pressure provided by each kicker unit () is independent of the pressure provided by the other kicker units ().

Handoff mechanism for a media production apparatus

A media-sheet stacking system () for stacking media sheets on a device output tray (OT) comprises a kicker () to advance a media sheet along the output tray by pushing a trailing edge of the media sheet as it exits the device, and a movable element () arranged to face the output tray across a space that receives media sheets exiting the device. A drive mechanism () is provided to drive the movable element in the direction of advance of the media sheet along the output tray.
