摘要： According to a method of adjusting a head gap, a wire dot head is set to a predetermined position of a reference head gap; a printing pattern for detecting printing time is printed by a plurality of pins; reference printing times of respective pins are detected. Next, a test printing is performed with test printing dots previously selected from printing data, and printing time of the test printing is detected. Then, the thickness of the printing media is calculated based on the reference printing time and the printing time of the test printing. At that time, a rule of thumb in which the difference of the printing time corresponds to the difference of the head gap, is used. Then, a shift amount of the wire dot head is calculated for setting the head gap to an optimum value according to the thickness of the printing media, and gap shifting mechanism shifts the wire dot head by the shift amount. This leads to highly accurate detection of the head gap and improves printing quality thereof.

摘要： A device for controlling the driving of a printing wire of a wire dot impact printer which effects the printing by impinging the printing wire upon a printing medium, and the amount of displacement is detected when the printing wire is moved or the printing timing is detected. Print recurring period of the printing wire, operation characteristics of the printing wire, or timing for driving the printing wire, is ajusted based on the amount of displacement of the printing wire or the printing timing that is detected. Therefore, there is provided the wire dot impact printer which performs the printing operation in an optimum manner and which effects the printing of high quality at all times.

摘要： A device for controlling the gap between a wire dot head and a printing medium in a wire dot impact printer which effects the printing by impinging the printing wire upon the printing medium. The device comprises means (15) for changing the gap, means (10) for detecting the displacement, and control means (2) for changing the gap into a proper value. The amount of displacement is detected when the wire is moved, and the gap is properly adjusted between the wire dot head and the medium based on the amount of displacement. There is provided the wire dot impact printer which adjusts the gap within short periods of time between the wire dot head and the medium, and which effects the printing of high quality at high speeds.

摘要： An electrophotographic recording apparatus comprises a photosensitive drum (11), a transfer roller (13), a high voltage power supply circuit (48) for applying a transfer voltage to the transfer roller (13) and a CPU (21) for controlling the entire apparatus. The high voltage power supply circuit (48) supplies an output voltage (Vo) corresponding to a control signal issued from the CPU (21) as the transfer voltage to the transfer roller (13). At this time, the high voltage power supply circuit (48) sends a current detection signal to the CPU (21) to inform the same of an output current (I) which flows to the transfer roller (13). On the other hand, the CPU (21) outputs a control signal to the high voltage power supply circuit (48), the control signal corresponding to said current detection signal output from the high voltage power supply circuit (48). As a result, even if the output current (I) is varied depending on the kind of the print medium (15) and the resistance of the transfer roller (13), it is possible to generate the output voltage (Vo) in accordance with the varied output current (I).
