Abstract:
1. A recording apparatus comprising: a recording head having a nozzle row that discharges a photoreactive liquid onto a recording target material; a light irradiation unit including a light emitting element row having therein a plurality of light emitting elements aligned in a same direction as the nozzle row, the light emitting elements being configured to apply light to the discharged photoreactive liquid to cause the photoreactive liquid to undergo a chemical change; a fault detection unit that detects whether there is a fault in each of the light emitting elements forming together the light emitting element row; and a control unit that controls a recording operation of the recording head and an operation of the light irradiation unit, wherein the light irradiation unit includes a plurality of the light emitting element rows arranged therein, wherein each of the light emitting element rows includes the light emitting elements connected in series, and wherein the control unit is configured to, in a case where the fault detection unit detects a fault in a light emitting element, enter a fault mode where one of the light emitting element rows to which the light emitting element having the fault belongs is turned off and recording is performed with the remaining light emitting element rows, wherein the control unit is configured to be able to execute control: in a case where the fault detection unit detects a fault in a light emitting element, to determine whether the fault has occurred in an open mode, if the fault has occurred in the open mode, to enter the fault mode where recording is performed with the remaining light emitting element rows, other than the light emitting element row to which the light emitting element having the fault belongs, if the fault has occurred in a short mode, to determine whether recording is possible in a case where the light emitting element row to which the light emitting element having the fault belongs is turned off, and if possible, to turn off the light emitting element row to which the light emitting element having the fault belongs and to enter the fault mode.
