    Abstract: The present disclosure provides a calibration method and a calibration device for a volume of an ink droplet and a printing apparatus including the calibration device. The calibration method for a volume of an ink droplet comprises: calculating a first volume of a single ink droplet based on a mass and a density of an ink droplet; calibrating a measurement parameter used in an optical measurement approach based on the first volume; and acquiring a second volume of a single ink droplet using the optical measurement approach based on the calibrated measurement parameter.

    Abstract: The present disclosure provides a device and a method for detecting a level degree of an OHCV. The device may include a laser beam transmission unit, at least one baffle, a laser beam reception unit, and a controller. The laser beam transmission unit, the baffle and the laser beam reception unit may be sequentially arranged at an identical horizontal level inside the OHCV. The at least one baffle may be provided with a via-hole. The laser beam transmission unit may be configured to generate a laser beam through the via-hole and toward the laser beam reception unit. The laser beam reception unit may be configured to receive the laser beam and transmit information about the received laser beam to the controller. The controller may be configured to monitor the real-time information about the laser beam. According to the present disclosure, it is able to conveniently detect the level degree of the OHCV, effectively reduce the workload of an inspector and enable the inspector to inspect the OHCV without entering an interior of the OHCV, thereby to prevent the normal operation and the cleanliness of the OHCV from being adversely affected.
