摘要： A multivoltage power supply which can output a plurality of high voltages in parallel. The voltage values of the respective outputs are feedback to an A/D converter. Each feedback signal is converted to a digital signal and the difference between the digital signal and a corresponding predetermined output voltage is then calculated in the form of a digital value. This digital value is inputted to a corresponding auto-reload timer, whereby a pulse signal having a pulse width corresponding to the digital value is output at a predetermined frequency.

摘要： An electrophotographic printer capable of changing its printing speed includes a change signal generating circuit for generating a speed change signal, a head scan cycle setting circuit for setting a cycle time of a scan line of an LED array head, and a motor speed setting circuit for setting a rotation speed of a photosensitive drum. Since the head scan cycle setting circuit and the motor speed setting circuit are activated in response to the speed change signal outputted from the change signal generating circuit, the operations of the photosensitive drum and the LED array head are synchronized with each other, so that the printer can print a fine image on a recording medium. The printer control unit including those circuits also includes control circuits for controlling a constant current supplied to a transfer roller, and for controlling a temperature of fixing rollers, to avoid unevenness of printing.

摘要： In an electrophotographic recording device which includes a number of consumable parts, there is provided a first memory for storing a currently integrated total number of prints, and a number of prints at replacement of each consumable part. A second memory stores a number of lifetime prints, which is a conversion of the life of each part into a number of prints. A processor performs a first calculation to calculate a number of prints for replaced consumable parts after such replacement and a second calculation to calculate a wear rate of the replaced consumable parts from the number of lifetime prints read out from the second memory, and from the number of prints calculated by the first calculation. An indication section indicates the wear rate obtained from the second calculation. The number of prints stored in the first memory for the consumable parts at replacement is written into the current total number of prints.

摘要： Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The first signal is transmitted to the LED head in the form of a real printing data signal that is to be printed on a basic raster line in synchronism with a line timing signal. The remaining bit data of the received video signal, which are not converted into the first signal, are converted into a second signal representing another data sequence, and then stored in a line buffer. The second signal stored in the line buffer is transmitted to the LED head in the form of a real printing data signal that is to be printed on an additional raster line in synchronism with an additional line timing signal. The LED head drive energy with which the basic raster lines are printed and another LED head drive energy with which the additional raster lines are printed are set independently of each other. The LED head may be provided with such a resolution function.
