Abstract: A conveyance device 20 of an inkjet printer 1 has a discharge roller 46 disposed on the downstream side of the printing position A in the forward conveyance direction, and a paper jam detector 83 disposed on the downstream side of the discharge roller 46. The paper jam detector 83 includes a driven roller 84, driven pressure roller 85, and an encoder 86 that detects the angle of rotation of the driven roller 84 . The driven roller 84 turns following movement of the continuous paper 2 passing between the driven roller 84 and driven pressure roller 85. The control unit 90 of the inkjet printer 1 detects occurrence of a paper jam based on the difference between the angle of rotation of the driven roller 84 and a reference angle of rotation when the conveyance motor 60 continues driving after the continuous paper has passed through the conveyance path 21.
