    摘要: A device for controlling a process of stopping a laser printer having a printing unit including a sensitive drum and a fixing unit. The stopping process control device is provided with a detecting unit for detecting errors occurring in the laser printer, a determining unit for determining whether or not an error detected by the detecting unit is very serious, and a control unit for controlling the printing unit and the fixing unit. The control unit stops the printing unit and the fixing unit after completing a printing and a fixing of the page being printed when the determining unit determines that the error is less serious, and conversely, immediately stops the printing unit and the fixing unit when the determining unit determines that the error is very serious.

    摘要: A device for feeding a continuous form in a printer, the device having a timer for controlling the width of a drive pulse for a main motor feeding the form. The timer is formed of a plurality of timers controlled by software. These plurality of timers being, for example, three timers measuring a constant time, and one timer measuring a variable time which is varied in accordance with a feeding speed of the form. The width of the drive pulse is determined by summing up a time obtained by multiplying the constant time by three and adding the variable time.

    摘要: A justification system is provided for use in an electrophotographic printer. The justification system comprises a detector which detects the passage of individual segments of a continuous form which are being fed at a predetermined rate. A counter counts the number of main scannings of a laser beam carrying printing information over the surface of a photoconductive drum. A read control is connected to the detector and the counter and controls reading of main information stored by monitoring outputs from the detector and the counter so that printing of each segment always occurs at a predetermined position, synchronously with passage of the segments.

    摘要: A continuous form printer is provided with two rotary encoders, corresponding to different paper feed intervals, and mounted coaxially on a drive shaft. The drive shaft drives a tractor for feeding the paper. The rotary encoders are read by photo-interruptor sensors, and the sensor signals are selected by a selector. The selector is able to select either one of the sensor signals generated by the encoders, or a signal formed by performing an AND operation on the two sensor signals. A controller controls a motor driving the drive shaft according to the selected signal, the selected signal corresponding to a chosen feeding interval. The controller is further able to precisely adjust the leading edge of the paper to a predetermined position based on the selected sensor signal, a known paper length, and a paper top sensor.

    摘要: In a fixing device employed in an electrophotographic imaging apparatus for fusing an unfixed toner image carrier on a recording sheet, a heat roller and a back-up roller are provided. The heat roller is provided with a heater mechanism installed therein, wherein the heater mechanism is arranged such that the temperature of a portion of the heat roller corresponding to the passing area of the recording sheet is higher than that of the other portions of the heat roller so that the temperature distribution of the heat roller heated by the heater mechanism becomes substantially uniform along its axial direction while the recording sheet is passing through the nip between the heat roller and the back-up roller.

    摘要: An imaging device is provided utilizing a continuous-form recording sheet (i.e., continuous-form sheeting), having a plurality of transverse perforations at predetermined intervals of length, on which the desired image is formed. At least an oscillating member which is driven by a rotating shaft is provided for oscillating continuous-form sheeting discharged from the imaging device. The oscillation caused by the oscillating member forwardly propagates the sheeting toward the imaging device. The continuous-form sheet is alternately and accurately folded at the transverse perforations in opposite directions, and stacked in a vertical direction between two folding positions as the continuous-form sheeting is discharged from the imaging device.
