A print liquid supply apparatus or interface structure to be connected to a print system comprises a liquid channel, liquid interface and integrated circuit contact pads.

Print liquid supply

A method for filling a reservoir of a printing device that includes conducting an unattended refill process of an internal reservoir in response to a detection of a fluid supply unit. In an example, the supply dock fluidically, electrically, and mechanically couples to the fluid supply unit to the printing device.

Unattended reservoir refillings

Print liquid supplies for printing devices are disclosed. A print liquid supply includes a container having a wall; a dock connector to enable selective coupling of the print liquid supply with a printing device; and a clamping support structure coupled with the dock connector, the wall of the container clamped therebetween. One of the clamping support structure or the dock connector including a tongue latched onto a groove in the other one of the clamping support structure or the dock connector.

Print liquid supplies for printing devices

An example apparatus may include a supply guide to receive a plurality of print supplies and a lock mechanism to retain the plurality of print supplies and release a print supply of the plurality of print supplies responsive to a determination that an amount of print substance in the print supply is at or below a threshold level.

Print supply locks

A serviceable machine includes a door assembly having a door, and a jointed assembly that extends between an external surface of the serviceable machine and the door. The jointed assembly is operable to move the door between a closed position in which an interior region of the serviceable machine is covered, and an open position in which the interior portion of the interior region is unobstructed. The jointed assembly may extend connectivity to the door when the door is in either the open or closed positions. Additionally, the door can mechanically and electrically decouple from the jointed assembly.

Door assembly for serviceable machine

A printer includes a housing, a print engine within the housing, a door to cover a portion of the housing, and a hinge assembly coupled to the housing and the door to support the door in a closed position to cover the portion of the housing and an open position to uncover the portion of the housing, wherein, in the open position, the door is offset from the housing by the hinge assembly.

Printer door hinge assembly

An example device includes a first member, a second member, and a hinge. The hinge pivotably couples the first member to the second member. The hinge includes a damper. The damper includes core, and the core has a lobed portion. In another example, a device includes a first mounting member, a second mounting member, a first connector pivotably coupled to the first mounting member at a first hinge and to the second mounting member at a second hinge, a second connector pivotably coupled to the first mounting member at a third hinge and to the second mounting member at a fourth hinge, and a damper positioned at least at one of the first hinge, second hinge, third hinge or the fourth hinge, the damper including core with lobed portion.

Hinge damper

Low-profile service stations for use with printers are described herein. One example service station includes a shuttle to support a cap sled. The shuttle has a shuttle drive and a pump drive positioned such that at least one of the shuttle drive and the pump drive does not extend between a first side and a second side of the shuttle. The shuttle drive is coupled to a printer drive to move the shuttle between a first position and a second position.

Low-profile service stations for use with printers

Apparatus and methods are provided for use with printers and imaging apparatus. An actuator is supported on a shaft about which it can rotate through a range of arc. A spring biases the actuator so as to bring a valve pad into sealing contact with a plurality of nozzles. A lever arm of the actuator is operable by way of force contact so as to rotate the actuator and angularly displace the valve pad out of contact with the nozzles. Simultaneous opening or closing of the nozzles is performed by way of corresponding angular displacements of the actuator.

Angular valve actuator

A print head cap includes a vent which is opened during storage of the print head against the cap, is closed during priming of fluid through nozzles of the print head and is opened to stop the priming. Pumping of fluid from the cap is started substantially immediately upon opening of the vent to stop priming.
