A printer includes a print head configured to print on a recording sheet, a platen roller attached to a frame in a rotatable manner, a support having a head spring attached thereto that urges the print head toward the platen roller, and a hold unit attached to the frame in a rotatable manner and having an engaging part that engages with a projection situated at a side end of the support, wherein the head spring is configured to urge the print head toward the platen roller when the projection is engaged with the engaging part, and wherein the hold unit is configured to be rotated to cause the engaging part to disengage from the projection.

An alignment of jet holes of a liquid jet head is smoothly performed. A liquid jet head according to an embodiment of the present disclosure includes a nozzle section having a jet hole for liquid, a support member configured to support the nozzle section, and a position adjustment mechanism configured to adjust a position of the jet hole with respect to a carriage. The position adjustment mechanism includes a reference member a position of which with respect to the carriage is fixable, a position adjustment member which is coupled to the support member, and is configured to push the reference member to change a relative distance with respect to the reference member to thereby displace the support member on the carriage, and an intermediary member intervening between the reference member and the position adjustment member. The intermediary member is attached to either one of the reference member and the position adjustment member to form a first pressure-receiving surface facing to a displacement direction of the support member, and the other of the reference member and the position adjustment member has contact with the first pressure-receiving surface.

An integrated inkjet module includes: a print module positioned between end brackets, the print module having an elongate printhead; a wiper carriage configured for longitudinally wiping the printhead; and a print module carrier supporting the print module. The print module carrier is slidably mounted between the end brackets for lifting relative to a media feed path. The wiper carriage, in a parked position, is positioned between one end of the print module and an end bracket, and the print module carrier includes a mounting arm bridging over the wiper carriage in the parked position.
