In one example, a platform lift includes a rotationally stationary leadscrew to support a platform, a rotatable nut to drive the leadscrew up and down through a range of motion, a first spring to apply a continuous downward force to the leadscrew throughout the range of motion, and a second spring to apply a continuous upward force to the leadscrew throughout the range of motion.

Lift to lower and raise a platform

In an example, a conditioner module may include a bridge to receive media from a media path of an imaging device and to deliver the media to a media input of a finisher module. The conditioner module may include a calender nip disposed at an output end of the bridge. The calender nip may compress the media and may feed the media into the media input of the finisher module.

Conditioner modules with calender rollers

Examples of an apparatus to use in a media feeder and a method to use in a media feeder are disclosed herein. An example of the apparatus includes a platen having an input to receive a medium and an output to eject the medium. The example of the apparatus additional includes a re-feed prevention device including a ramp to deflect the medium away from the input of the platen when the medium exits the output of the platen and a hooked end to catch an edge of the medium when curled as the medium exits the output of the platen.

Re-feed prevention

Examples disclosed herein relate to a device including a separator. Examples include a first separator having a surface to contact a medium and is coupled to a first spring. In examples, the first separator has a first centerline in a direction perpendicular to a medium travel direction. Examples include a second separator having a surface to contact a medium and is coupled to a second spring. In examples, the second separator has a second centerline disposed substantially parallel to the first centerline. Examples include a roller to contact the medium to move the medium along the medium travel direction. In examples, the first spring and second spring bias the first separator and second separator towards the roller, respectively. In examples, a force applied by the first separator to the medium is independent of a force applied to the medium by the second separator.

Device including separator

In one example, a system for a partially dried inkjet media conditioner includes a partially dried Inkjet media conditioner, including: a first connector to couple a first end of the conditioner to a printing device, a second connector to couple a second end of the conditioner to a finishing device, and a constrained path extending through the conditioner to receive partially dried inkjet media from the printing device and provide the partially dried Inkjet media to the finishing device.

Partially dried inkjet media conditioner

In one example, a system for partially dried inkjet media fusers include a plurality of fusers aligned to receive partially dried inkjet media from a printing device, wherein the plurality of fusers each comprise a top roller and a bottom roller to apply pressure to the received partially dried inkjet media, and a finisher to receive the partially dried inkjet media from the plurality of fusers.

Partially dried inkjet media fusers

In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.

Translatable scanner calibration target

In an example implementation, a fluid supply assembly includes a printhead assembly and a carriage comprising a quick-release, hand-operable attachment mechanism to removably attach the printhead assembly to the carriage. A fluid conduit interconnect is rigidly attached to the printhead assembly by a tool-operable fastener. The fluid conduit interconnect is to connect to a fluid conduit to communicate printing fluid from an off-axis printing fluid supply to the printhead assembly.

Fluid supply assembly

In an example implementation, a fluid supply assembly includes a printhead assembly and a fluid conduit interconnect to connect to a fluid conduit to communicate printing fluid from an off-axis printing fluid supply through the fluid conduit interconnect to the printhead assembly. The fluid supply assembly includes a carriage with a dual attachment mechanism to simultaneously attach the printhead assembly to the fluid conduit interconnect and to the carriage by a single user action.

According to an example, an apparatus to prevent media transport jams may include an actuator to load and advance a media within a media path width. The apparatus may also include a first sensor and a second sensor to detect respective edges of the media, in which the first sensor and the second sensor may be positioned outside of a media action area and on opposite sides of the media path width. The apparatus may further include a controller to prevent the actuator from advancing the media along the media path in response to a detection of one or both of the first edge of the media by the first sensor and the second edge of the media by the second sensor.

Media transport jam prevention

An off-axis printhead assembly includes a printhead body that has an engagement element removably attachable to an attachment mechanism of a carriage of a printing system, the attachment mechanism of the carriage removably attachable to an on-axis printhead assembly. A fluid conduit interconnect is removably attached to the printhead body, the fluid conduit interconnect to connect to a fluid conduit to communicate printing fluid from at least one off-axis printing fluid supply through the fluid conduit interconnect to the printhead body.

Off-axis printhead assembly attachable to a carriage

Examples of a mounting device and method are disclosed herein. An example of the mounting device includes a carriage to hold a printhead assembly and an interconnect assembly to supply printing composition to the printhead assembly. The mounting device also includes a first latching assembly having an engaged condition to lock the interconnect assembly to a manifold of the printhead assembly and a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly. The mounting device additionally includes a second latching assembly having an engaged condition to lock the printhead assembly to the carriage and a disengaged condition to unlock the printhead assembly from the carriage. In this example of the mounting device, the second latching assembly cannot be moved from the engaged condition to the disengaged condition unless the fast latching assembly is in the disengaged condition.

Mounting device

A separator assembly is disclosed herein. An example includes a base to mount to a printing device and a wall supported by the base. The example also includes a singulation assembly adjacent the wall to separate a medium from a media stack and a ramp adjacent the singulation assembly to guide the medium from the media stack to a feed assembly. The example further includes a corner relief feature on either side of and below the ramp into which corners of the medium may drop and travel below a remainder of the medium as the medium is guided from the media stack to the feed assembly and a guide adjacent each corner relief feature to lift the corners of the medium out of the corner relief features before the medium enters the feed assembly. A media handling assembly is also disclosed herein as is a method of media handling.
