Abstract: An image forming apparatus which is capable of obtaining stable and satisfactory cleaning performance and fixing performance without holding, in an image forming unit which forms an image on a recording material based on a video signal, data for performing maintenance of the image forming unit. A synchronization signal output from the image forming unit and indicative of timing with which the video signal is output is detected. It is determined whether the synchronization signal is a normal synchronization signal for outputting a video signal for use in forming an image on the recording material or a pattern synchronization signal for outputting a pattern signal that is a video signal for use in performing maintenance of the image forming unit. When the synchronization signal is the normal synchronization signal, the video signal is output. When the synchronization signal is the pattern synchronization signal, the pattern signal is output.

Abstract: A marking device for encoding metallic workpieces with two-dimensional matrix codes includes a striking tool for forming the code recesses, driven by an electromagnetic device. The driving movement is performed against the force of a return device. A positioning device displaceable on two axes (x, y) of a plane perpendicular to the striking direction (z) is used for positioning the striking tool in the desired code positions. An electronic control device for controlling movement of the striking tool includes means for presetting a higher current for the electromagnet device during a first acceleration phase of the striking tool and a lower current during a subsequent moving phase until the workpiece is impinged. In this manner, the precision of the code recesses in the workpiece can be exactly set or maintained, so that readability of the coding is substantially improved.

Abstract: With an impact dot printing head control apparatus according to the invention, the drive control of respective wires is implemented on the basis of a normal fire and a pre-fire by generating the normal fire for driving the respective wires of the impact dot printing head so as to reach a printing position on the basis of printing data and a driving frequency of the impact dot printing head, and by generating, prior to the normal fire, the pre-fire for driving the respective wires so as not to reach the printing position. As a result, since the respective wires are caused to move by the pre-fire before actual printing operation by the normal fire even without preparing a large power source so as to meet requirements for driving the respective wires at the time of low temperature, the performance of the impact dot printing head can be ensured even at the time of low temperature, and in addition, reduction in product cost and downsizing of a product can be implemented.

Abstract: A method of controlling noise in an impact printer that modulates the input pulse to the power amplifier of the printer. The resulting current waveform is then applied to the print wire solenoids. The final shape of the force input to the platen reduces or spreads the spectral envelope containing problem harmonics and acoustic output noise.

Abstract: An ink density closed loop control system for an ink ribbon of an impact printer having a reservoir roller formed of an ink absorbent material with at least one or more channels within the reservoir roller fluidly connected to a pump and ink supply. A transfer roller can contact the reservoir roller for imparting ink to the ink ribbon. A sensor senses the relative amount of ink on the print ribbon and an electrical drive responsive to the sensor drives the pump for a flow of ink to the one or more channels. The sensor can sense ink on different segments of the ribbon and, with two or more channels in the reservoir roller can distribute ink to two or more segments of the reservoir roller depending upon the ink sensed at a particular segment of the ribbon. A further enhancement of this invention provides a multi-viscosity ink to compensate for changes in ambient temperature conditions.

Abstract: A color thermal printer has a feed roller set, a thermal head, and a tension roller set that are serially arranged along a transporting path. The feed roller set and the tension roller set are rotated by respectively a stepping motor and a DC motor. The stepping motor rotates forwards. Simultaneously, the DC motor rotates the tension roller set forwards, to apply a first transporting force to the continuous recording sheet at a level higher than a predetermined transporting force of the feed roller set. Also, the stepping motor rotates backwards. Simultaneously, the DC motor rotates the tension roller set backwards, to apply a second transporting force to the continuous recording sheet at a level lower than the predetermined transporting force.

Abstract: A combination printer is described. The combination printer includes a thermal head and an ink printing head, such as a thermal transfer printing head. The thermal head thermally prints on thermal paper by heating. The thermal transfer printing head prints ink on the thermal paper by thermally transferring ink from an ink film to the thermal paper. The thermal transfer head is preferably positioned downstream relative to the first head along a paper flow path of the thermal paper. The printer further includes a first platen that serves as a back support for the thermal head, and a second platen that serves as a back support for the thermal transfer printing head.

Abstract: An inkjet printer having an envelope comer printing apparatus that prints print data on the comer of an envelope independently from the printing function performed by the printer with respect to the sheet media printed by the printer. The printer housing includes a slot in a front corner positioned to receive an envelope corner for purposes of printing print data such as a return address or postage on the envelope corner. The printhead of the printer is capable of being positioned over the slot in the front corner of the printer housing and a sensor located within the printer housing near the slot detects the insertion of the envelope corner and initiates printing by the printhead. The printhead prints the print data from the non-volatile memory of the printer and does not require constant interfacing between the printer and the computer attached to the printer.
