  • Inkjet printer having a paper edge cover
    Patent number: 8870362
    Abstract: An inkjet printer (1) has an inkjet head (7), a paper conveyance path (6) that conveys tractor feed paper (2) passed the printing position P of the inkjet head (7), and a pair of paper edge covers (21L, 21R) disposed on the opposite sides of the conveyance path portion passing the printing position P of the paper conveyance path (6). The paper edge covers (21L, 21R) are covers that cover and hide the edge portions (2L, 2R) where the sprocket holes (2a) of the tractor feed paper (2) conveyed passed the printing position P are formed from the inkjet head (7). The paper edge covers (21L, 21R) can reliably prevent problems such as nozzle clogging caused by paper dust from the sprocket holes (2a) at the edges of the tractor feed paper (2) clinging to the nozzle face (7a) of the inkjet head (7).
