摘要： A paper feeding control system of an automatic paper feeder has a setting device for enabling a position to head a printing medium to be reset. The setting device consists of a read/write enable nonvolatile memory for holding a reset value of the heading position of the printing medium. Upon taking in and setting the printing medium, an operating panel switch is operated to correct the heading position of the printing medium. In addition, the corrected value is again written in the memory, whereby the heading position of the printing medium can be corrected and altered.

摘要： A method of automatically inserting a printing paper in a hopper of an automatic paper feeder or a manual insertion printing paper inserted from a manual paper input slot. Upon receiving an instruction to insert a printing paper by a printer, a platen is first rotated. Thereupon, provided the presence of the printing paper is detected by a sensor even with the platen being rotated by a prescribed amount, a paper feed motor of the automatic paper feeder is rotated for obtaining a printing paper from the hopper. While, provided the presence of a printing paper is detected before the platen is rotated by the prescribed amount, the paper feed motor is not rotated, it being assumed that the manual insertion of a printing paper has been already performed. After detected the presence of the printing paper, the platen is rotated by a prescribed amount to cause the printing paper to be moved to a position where a first line of the printing paper faces the face of the printing head.

摘要： The operation of an automatic sheet feeder provided with a plurality of sheet hoppers which are used selectively to feed sheets to a printer is controlled. A control unit of the printer supplies a multiplex control signal including a hopper select signal and a sheet delivery signal to the automatic sheet feeder through a single signal line. The width of pulses of the hopper select signal is smaller than a predetermined time, while the width of the sheet delivery signal is greater than the predetermiend time. The pulses of the multiplex control signal are compared with the predetermined time to discriminate the hopper select signal and the sheet delivery signal from each other. That sheet hopper corresponding to the number of pulses of the hopper select signal is selected, and then the automatic feeding of sheets from the selected sheet hopper commences upon the reception of the sheet delivery signal.

摘要： A method of controlling a cut-sheet feeder installed on a printer to feed a cut sheet from a sheet hopper (1) included in the cut-sheet feeder to the printing unit of the printer at a sheet feeding speed corresponding to that of the printer. The printer gives a correction signal (S.sub.1) of a predetermined pulse width to the cut-sheet feeder, and then the cut-sheet feeder converts the pulse width of the correction signal into a corresponding number of pulses of a clock signal generated by its control unit (25), and obtains the difference between the number of pulses of the clock signal and a predetermined reference value to determine the deviation of the frequency of the clock signal from a reference frequency. The difference between the number of pulses of the clock signal and the reference value is added to a reference motor controlling value for driving a stepping motor (4) at a reference speed to obtain a corrected motor controlling value. When the printer gives a sheet feed command signal (S.sub.f) to the cut-sheet feeder, the stepping motor is driven for rotation according to the corrected motor controlling value.

摘要： A driving apparatus has driving circuits that supply driving energy to driven elements which form dots. The driving circuits are controlled by driving data indicating which driven elements are to be driven, and compensation data adjusting the amount of driving energy. The compensation data are stored in compensation memory circuits coupled to the driving circuits. A single data transfer means transfers the driving data to the driving circuits and the compensation data to the compensation memory circuits. If the driven elements are located on two or more different semiconductor chips, some of the compensation data preferably compensate for chip-to-chip differences, while other compensation data compensate for dot-to-dot differences within the same chip.

摘要： Adjustment of correction data for the respective LEDs at the end of manufacture of a print head is performed by transferring provisional correction data from a manufacturing device to an LED driver, directly, i.e., without once being stored in a storage circuit 10c in the print head, and measuring the amounts of light from the LEDs and varying the correction data, and repeating such an operation until the correction data is optimized. The optimized correction data as well as the strobe time data determined from the measured average power are written in the storage circuit 10c. During use of the printer, the data stored in the storage circuit 10c is used for correction of the data and determination of the strobe time.
