摘要： In one aspect, a carrier recovery apparatus of a liquid electrophotographic printer includes a drying unit, a cooling unit for cooling and condensing carrier vapor evaporated by the drying unit, a condenser for condensing the carrier vapor which has not been condensed by the cooling unit, and a carrier recovery container. In another aspect, a carrier recovery apparatus of a liquid electrophotographic printer includes a drying unit, a first cooling unit for cooling and condensing carrier vapor evaporated by the drying unit, a second cooling unit for cooling the carrier which has passed through the first cooling unit, a condenser for condensing the carrier vapor which has not been condensed by the first and second cooling units, and a carrier recovery container. Accordingly, the efficiency of condensing carrier vapor is improved. As a result, the recovery percentage of a carrier increases, and the duration of a filter is extended.

摘要： Disclosed is a device for measuring the density of an image in regard to a liquid test patch. The device has: a fan for drying a test patch by blowing air to the test patch disposed on at least one of a photosensitive medium, a photosensitive belt and printing paper; a sensor for projecting infrared light to the dried test patch and measuring the density of the test patch based on the reflected light of the infrared light reflected from the test patch; and an adjustment unit for adjusting the mixing ratio of a toner and a carrier in accordance with the measured density. The device measures the amount of light reflected from the dried liquid test patch, thus allowing the density of the image to be measured accurately.

摘要： An optical signal control process and circuit providing an improved electronic photography method reproduction apparatus. The reproduction apparatus has a data transmitting unit converting data to be printed to a series of video data in accordance with a first clock signal and transmitting the converted video data in response to a horizontal synchronization signal applied with a predetermined time interval, and a printing control unit for controlling a mechanism used to print the video data by sending electrical signals, providing beam data used to switch the light generation of a light source element controlled by chopped chopping video data applied to the light source element, and generating the horizontal synchronization signal on the basis of a beam detection signal produced by the light source element. A chopping unit is connected between the data transmitting unit and the printing control unit, for chopping the converted video data output from the data transmitting means in response to a second clock signal and for providing the chopped data as the chopping video data. Accordingly, the chopped video data is transmitted as beam data by the printing control unit and is then used to control the amount of light exposed on the photosensitive drum. The amount of the light is controlled optimally by the variable selection of the frequency of the second clock signal.
