Manufacturing method for liquid ejecting head unit, and liquid ejecting apparatus

A manufacturing method for a liquid ejecting head unit, the liquid ejecting head unit comprising:

• a plurality of liquid ejecting heads, each liquid ejecting head having a nozzle row in which nozzles that eject a liquid are arranged in a row;
• a base plate to which the plurality of liquid ejecting heads are anchored;
• an anchoring plate, anchored to the base plate, for positioning the liquid ejecting heads in predetermined positions relative to the base plate;
• and
• a reference mark formed in the anchoring plate and a positioning mark formed in the base plate for positioning the anchoring plate relative to the base plate,
• wherein a plurality of the positioning marks are formed along the direction in which the nozzles are arranged in a row, and
• the manufacturing method includes:
• selecting the positioning mark in accordance with a predetermined resolution;
• anchoring the anchoring plate to the base plate so that the reference mark and the selected positioning mark are in the same relative positional relationship;
• and
• anchoring the liquid ejecting heads to the base plate using the anchoring plate.
