摘要： A method of reducing the `downtime` of the printing line involves the inclusion of at least one spare printing module, and a method of transferring digital representations of page images between modules. As soon as a fault is detected, a digital image data describing the sheet printed by the faulty module is transferred to the adjacent printing module downstream from the faulty module. The data in this module is simultaneously sent to the module downstream of it. This process repeats until a page image is sent to the spare printing module, which is best located as the most downstream of all the printing modules. Once all of the data has been transferred, printing can recommence. If this data transfer can occur in less than the time required to print a sheet, the line can continue printing without stopping, and without any wastage of printed copies. If more than one spare printing module is included at the end of the printing `assembly line`, then more than one simultaneous fault can be accommodated without productivity loss.

摘要： To prevent effective print speed from being lowered, a counter is provided for each of a plurality of print hammers. A number of times a print hammer is driven during one print phase having a predetermined period of time is counted by the counter. The counted value is compared with a reference value, and when the counted value has reached the reference value during the print phase, driving of the print hammer is halted until the end of the print phase. A reference value is changed based on the number of times the print hammer is driven during a previous print phase immediately before the present print phase. The reference value represents an allowable number the print hammer can be driven during each of successive print phases.

摘要： A power supply supplies an a-c power as primary electric power and a d-c power as secondary electric power. A converter converts the primary electric power, for example, 100 VAC into the secondary electric power, for example, +5 VDC and +24 VDC. The primary electric power is used to heat, for example, a heat roller of a printer. An abnormal-temperature detector outputs a detection signal when the temperature of the heat roller heated by the primary electric power exceeds a predetermined temperature. A controller causes the converter to draw an additional current from the primary electric power in response to the detection signal so that a current drawn from the primary electric power exceeds a predetermined current. An abnormal current interrupter shuts down the current drawn from the primary electric power when the current drawn from the primary electric power exceeds the predetermined current. The power supply may have an abnormal current detector instead of the abnormal-temperature detector. The abnormal current detector outputs a detection signal when a current supplied to the heat roller continues to flow longer than a predetermined period, and outputs a detection signal. The controller causes the converter to draw an additional current from the primary electric power in response to the detection signal so that a current drawn from the primary electric power exceeds a predetermined current.

摘要： To prevent undue elevation of temperature in a hammer assembly but to maintain the maximum printing speed, when a scheduled number of drivings at which print hammers are to be driven during one scan of a manner bank which follows the currently performing scan, exceeds a first reference number, one dot line printing is completed with a plurality of scans of the hammer bank so that dot line print density in each scan of the hammer bank does not exceed, for example, 35%. If, however, high density printing exceeding 25% continues for an extended period of time more than one scan time, the printing operation is temporarily halted.

摘要： A printing mode setting portion outputs energizing time data corresponding to a selected printing mode when selecting the printing mode according to operation of the operation unit. Based on the energizing time data, the energizing time period of a head energizing signal which is output from a head driving portion to a driving coil of a dot printer head is controlled by the energizing time control portion 6. When printing mode having a high dot density is selected, printing energy is reduced and the energizing time period is refined for the driving coil 8, thus making it made possible to lower the noise level.

摘要： A driving device for a piezoelectric element is provided which attains lower power consumption, low heat generation and low cost. To displace a piezoelectric element, a first switching transistor is rendered ON by a control circuit. The electric charges flow in the piezoelectric element from the power supply through the first switching transistor. This state is continued until a sufficient amount of electric charges are stored in the piezoelectric element. To restore the piezoelectric element thus displaced, a second switching transistor is rendered ON under the condition where the first switching transistor is OFF. In this condition, a resonance circuit is formed by the piezoelectric element and the coil. When the electric charges are flowing in the coil and a predetermined period of time has elapsed after the second switching transistor is rendered ON, the control circuit renders the second switching transistor OFF, whereby the current flowing in the coil flows into the power supply.

摘要： Piezoelectric elements that can resonate at a certain frequency with a coil are extended and contracted as they are repeatedly charged and discharged. The extending and contracting movements of the piezoelectric elements are amplified and transmitted to move the print wires toward and away from the platen. The waveform of a voltage generated across the piezoelectric element is detected by a monitoring device. Then, the detected voltage waveform is compared with the waveform of a voltage that is produced when the print gap is proper, and lets the user to know the magnitude of the print gap between the distal ends of print wires and a platen at any time during printing operation.
