An inkjet recording device including: a recorder; a mover; and a hardware processor, wherein a pair of recording heads having recording elements in overlapping arrangement ranges in a width direction are at positions different in one movement direction orthogonal to the width direction, ink changes the phase to a solid in a time shorter than a difference between times when the ink adheres to a same position in the one movement direction, the hardware processor performs recording control of causing a selected recording element to perform an output operation to each position in the one movement direction and determines an execution order of output operations such that the output operation by each of downstream-side recording elements is performed twice or more continuously and at least a part of the output operations by upstream-side recording elements is not continuous.

A drive unit is configured to generate a drive signal for driving a liquid ejecting head unit. The drive unit includes a drive board on which a drive circuit configured to generate the drive signal is mounted; a thermal conductive material that is in contact with the drive circuit on an opposite side in relation to the drive board; a water cooling mechanism that is in contact with the thermal conductive material on an opposite side in relation to the drive circuit; a pump that causes liquid in the water cooling mechanism to flow; and a control circuit that controls operation of the pump. The control circuit switches a direction in which the pump causes the liquid to flow between a forward direction and a reverse direction that is an opposite of the forward direction.

Provided is a drive circuit unit generating a drive signal for driving a head, the drive circuit unit including: a drive circuit generating the drive signal; a first connector coupled to the head; a first substrate on which the first connector is mounted; a fan generating wind for the drive circuit; and a second substrate on which the fan is mounted.

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.

A print bar for a for a multi-pass printer, the print bar comprising a static part configured to extend across a print area of a print target and a moveable part comprising a print bar beam and printer comprising such a print bar.
