Printer
First Claim
1. A printer in which printing is conducted by discharging ink droplets from a plurality of nozzles, comprising:
- a printer head which is capable of conducting full-line printing on a printing paper, without scanning in the width direction of said printing paper, and which is provided with a plurality of said nozzles;
paper transportation means that is provided with an endless transportation belt and disposed opposite the ink discharge surface of said printer head so as to hold and transport said printing paper in the transportation direction perpendicular to the width direction of said printing paper;
printing control means for conducting printing by controlling the discharge of fine ink droplets from said printer head synchronously with the printing paper transportation operation of said paper transportation means; and
recovery means for recovery of discharge function of nozzles of said printer head, said means being insertable and retractable with respect to the printer head in the lateral direction perpendicular to said transportation direction and parallel to the transportation surface of said transportation belt which supports the printing paper.

Abstract
A printer comprising a printer head disposed above a transportation belt and composed of a plurality of head units having an ink discharge surface, a paper attraction apparatus, and an ink discharge surface recovery apparatus, wherein in order to conduct the recovery treatment of the ink discharge surface, the printer head is moved upward and the recovery apparatus is inserted into the gap formed between the printer head and transportation belt in the direction perpendicular to the paper transportation direction of transportation belt. 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 such printer, the recovery treatment of the ink discharge surface can be easily conducted, the increase in the printer size is avoided, and the adjustment, maintenance, and control can be easily conducted.
