An apparatus for adjusting a head gap between printing paper and a nozzle of a printing head in an inkjet printer includes a carrier mounted with the printing head, a chassis having a carrier shaft guiding a movement of the carrier, an eccentric cam formed on one end of the carrier shaft, a carrier driving part moving the carrier right and left along the carrier shaft, and a paper-transporting roller driving part driving a paper-transporting roller of transporting printing paper to be printed. The apparatus includes a carrier ascent/descent part ascending and descending the carrier by rotating the carrier shaft, and a clutch device selectively transmitting a driving force of the paper-transporting roller driving part to the carrier shaft to rotate the carrier shaft and disposed to be actuated by the carrier which is moved by the carrier driving part when the head gap should be adjusted. Accordingly, the apparatus can automatically adjust the head gap by using only the driving force of the carrier driving part and the paper-transporting roller driving part without using a separate driving motor.
