A device outputs a first low voltage to a first terminal at a first timing in a period in which a voltage input to a second terminal is a high voltage. After outputting the first low voltage, the device outputs a second high voltage to the first terminal at a second timing in a period in which the voltage input to the second terminal is a low voltage. After outputting the second high voltage, the device outputs a second low voltage to the first terminal at a third timing in a period in which the voltage input to the second terminal is a high voltage.

In one example in accordance with the present disclosure, a fluidic die assembly is described. The fluidic die assembly includes a rigid substrate having a bend therein. A fluidic die is disposed on the rigid substrate. The fluidic die is to eject fluid from a reservoir fluidly coupled to the fluidic die. The fluidic die includes an array of ejection subassemblies. Each ejection subassembly includes an ejection chamber to hold a volume of fluid, an opening, and a fluid actuator to eject a portion of the volume of fluid through the opening. The fluidic die assembly also includes an electrical interface disposed on the rigid substrate to establish an electrical connection between the fluidic die and a controller. The fluidic die and the electrical interface are disposed on a same surface on opposite sides of the bend.

In some examples, a print bar fabrication method comprises placing printhead dies face down on a carrier, placing a printed circuit board on the carrier, wire bonding each printhead die of the printhead dies to the printed circuit board, and overmolding the printhead dies and the printed circuit board on the carrier, including fully encapsulating the wire bonds.

In a board that includes a plurality of contact portions that are arranged to contact corresponding apparatus-side terminals when the board is mounted in a printing apparatus, some contact portions are disposed in a first region, and the remaining contact portions are disposed in a second region. The some contact portions include a first contact portion, a second contact portion, a third contact portion, and a fourth contact portion. The remaining contact portions include a fifth contact portion. The some contact portions are arranged in a first pattern in the first region and the remaining contact portions are arranged in a second pattern in the second region, and the first pattern is asymmetrical to the second pattern with respect to a first virtual line.

A printing-fluid cartridge is inserted into a printing-fluid consuming apparatus in an insertion direction crossing a gravitational direction and attached thereto in a first posture. The printing-fluid cartridge includes: a storage chamber, a supply portion having a supply port, an upper surface and a locking surface positioned upward of the storage chamber, an electrical interface disposed at the upper surface, and a contact surface positioned rearward relative to the supply port of the supply portion in the insertion direction in the first posture. The printing-fluid cartridge inserted in the printing-fluid consuming apparatus is movable between the first posture and a second posture. In the first posture, the locking surface engages a lock portion and the contact surface abuts against a positioning portion. In the second posture, the locking surface is positioned downward relative to the lock portion and the contact surface is separated from the positioning portion.

A printing-fluid cartridge is inserted into a prescribed insertion space of a cartridge-attachment section in an insertion direction crossing a gravitational direction to be attached thereto in an attached posture. The printing-fluid cartridge includes: a housing including a storage chamber, a supply portion having a supply hole, an electrical interface disposed at an upper surface of the housing, and an interfering surface. The interfering surface is positioned upward of the storage chamber and extends in a widthwise direction of the housing. The interfering surface is positioned downward and frontward relative to the electrical interface and is configured to abut against a projection provided at another insertion space different from the prescribed insertion space of the cartridge-attachment section during an insertion of the printing-fluid cartridge into the another insertion space.

A liquid cartridge includes a housing, a circuit board including an electrode, and a liquid supply portion extending from the housing in a depth direction. The housing includes a top wall, and first and second protrusions protruding upward from the top wall. The first protrusion is positioned rearward but the second protrusion is positioned frontward relative to the circuit board. The first protrusion is higher than an upper edge of a front end of the second protrusion. No part of the liquid cartridge is positioned higher than an imaginary plane in a height direction in a region between a first point on the first protrusion and a second point on the second protrusion (the upper edge of the front end of the second protrusion) in the depth direction. The imaginary plane passes through the first and second points, and extends perpendicularly to the depth direction.

A memory includes: a first type storage area used in a one-time use period from when a liquid is filled into a cartridge to when consumption of the liquid is completed; and a second type storage area used in an entire use period of the cartridge, which is a set of one-time use periods, in which the first type storage area has a plurality of individual areas in which a different area is used in each one-time use period.

A method of installing a printhead in a print module includes the steps of: positioning the printhead in a nest of the print module; moving first and second ink couplings towards the nest and into engagement with complementary first and second ink ports positioned at opposite ends of the printhead; and moving a depressor towards the nest and into urging engagement with a portion of the printhead positioned between the first and second ink ports. The first ink coupling, the second ink coupling and the depressor are moved simultaneously, linearly and parallel to each other, thereby to datum the printhead against the nest.

A printing fluid cartridge includes a front face oriented toward a first direction, a printing fluid supply portion positioned at the front face, a rear face positioned opposite the front face and oriented toward a second direction opposite the first direction, at least one electrical interface positioned between the front face and the rear face, and an engagement surface facing in the second direction. The at least one electrical interface is offset from the printing supply portion with respect to a third direction perpendicular to the first direction and the second direction. The at least one electrical interface is positioned closer to the front face than the engagement surface is, and the at least one electrical interface and the engagement surface intersect a plane which is parallel with the first direction, the second direction, and the third direction.
