Abstract
A printer is provided which includes a printer head disposed above a transportation belt, a paper attraction apparatus, and an ink discharge surface recovery apparatus. In order to conduct recovery treatment of an ink discharge surface, the transportation belt is retractable and the recovery apparatus is inserted into the gap formed between the printer head and transportation belt in a direction perpendicular to a paper transportation. In the inserted state, ink is discharged from the ink discharge surface toward a cap of the recovery apparatus, the clogged state of the nozzle is eliminated, and recovery treatment is completed. The recovery apparatus is thereafter retracted to the side of transportation belt. With this structure, the recovery treatment of the ink discharge surface can be easily conducted, an increase in the printer size is avoided, and adjustment, maintenance, and control can be easily conducted.
