A system for performing substrateless and/or local donor Laser Induced Forward Transfer (LIFT), comprising a reservoir comprising at least one opening and an energy source configured to deliver energy to a donor material within said reservoir, characterized by at least one of: said reservoir is embedded into a medical device; said reservoir is in fluid connection with a medical device; said reservoir is incorporated into a medical device; said reservoir contains at least one biologically active substance; and, said reservoir is in fluid connection with at least one source of at least one biologically active substance. This system enables deposition of material by LIFT without any need for a donor substrate. Methods of substrateless and local donor LIFT, in particular for medical and biological applications, are also disclosed.

A liquid ejection head is provided which comprises a channel member and a housing. The channel member comprises a first surface, which includes one or more ejection ports configured to eject liquid from the first channel member, and a second surface different from the first surface. The housing is disposed on the second surface and comprises one or more electric circuits. The second surface of the channel member comprises a first opening located outside of the housing and is configured to receive the liquid supplied to the one or more ejection ports.

A liquid ejection head 2 in the present disclosure is provided with a first channel member 4 including a first surface 4-1, a plurality of ejection ports in the first surface, a plurality of pressurizing chambers which are individually communicated with the plurality of ejection ports, and a second surface 4-2 on the opposite side to the first surface 4-1; with a pressurizing member on the second surface 4-2; and with a second channel member 6 including a third surface 6-3, a fourth surface 6-4 on the opposite side to the third surface 6-3, a raised part 6e which protrudes from the fourth surface, and a first through hole 6a in the raised part 6e. The second channel member 6 is provided on a region in the second surface 4-2 of the first channel member 4, in which the pressurizing member is not arranged. When viewed on a plane, an outer circumference 7a of the raised part is located on inner side from an outer circumference 7b of the fourth surface 6-4.

An ink jet recording apparatus is provided with a conveying unit, a drive roller controller and a discharge timing controller. The drive roller controller controls a rotation speed of a drive roller based on pulse signals output by an encoder and corresponding to an angular velocity of a driven roller and an actual outer diameter of the driven roller. The discharge timing controller controls an ink discharge timing based on signals obtained by attenuating multiple frequency components of a target frequency corresponding to a pulse number of the pulse signals output from the encoder during one turn of the driven roller in the pulse signals and an actual outer diameter of the driven roller.

There is provided a controller for an image recording device. The image recording device includes: a carriage capable of moving in a first direction; a head mounted on the carriage and configured to discharge a liquid from a nozzle; and a wiper capable of being impregnated with a cleaning liquid, a nozzle surface of the head including a first region not having the nozzle and a second region having the nozzle. The controller is configured to execute: a pressing-against processing of abutting the wiper on the first region in a state in which a speed of a relative movement in the first direction between the carriage and the wiper is a first speed; and a moving processing of moving the carriage and the wiper relative to each other in the first direction at a second speed faster than the first speed, while abutting the wiper on the second region.

The second channel member 6 is provided on a region in the second surface 4-2 of the first channel member 4, in which the pressurizing member is not arranged. When viewed on a plane, an outer circumference 7a of the raised part is located on inner side from an outer circumference 7b of the fourth surface 6-4.
