Abstract

An inkjet recording apparatus includes a recording head formed with nozzles for jetting light curable ink onto a recording medium, a light irradiator having a light source for emitting light to cure the ink, and an illuminance detecting device for intermittently detecting an illuminance of the light emitted from the light source, at a predetermined interval. The inkjet recording apparatus further includes a temperature adjusting device for adjusting a temperature of the light source, and a control section for determining that the ink cannot be cured, if the illuminance detected by the illuminance detecting device is not higher than a reference value in a condition where the temperature of the light source has been adjusted into a predetermined range by the temperature adjusting device.

Claims9

Dependent claims

An inkjet recording apparatus, comprising:

a recording head comprising nozzles for jetting light-curable ink onto a recording medium;
a light irradiator having a light source for emitting light to cure the ink, the light source having a base section to which electric power is supplied;
a base temperature detecting device which detects a temperature of the base section;
a temperature adjusting device for adjusting a temperature of the light source;
an illuminance detecting device for detecting an illuminance of the light emitted by the light source;
and
a control section which controls the temperature adjusting device to control the temperature of the base section to be within a predetermined range, based on the temperature of the base section detected by the base temperature detecting device, and which determines that the ink cannot be cured, if the illuminance detected by the illuminance detecting device is not higher than a reference value when the temperature of the base section has been adjusted to be in the predetermined range by the temperature adjusting device.
