Definitions
- the invention relates to an electrographic printing device with at least one printing unit with: a toner image carrier, on the circumferential surface of which toner can be applied in accordance with an image-shaped distribution.
- Such a printing device is used in a printer or copier, an electrographic method being used to apply a latent image to the toner image carrier.
- This can e.g. by exposing a photoconductor or by magnetizing a magnetically sensitive layer.
- Toner attaches to the latent image in accordance with the image-like distribution of the electrical charges or the magnetic poles.
- This toner is transferred to a carrier material, generally paper, at a transfer printing part and later fixed on it.
- a device with such a printing device should work quickly and be flexible in use.
- toner images must be printed on a form that has form windows that have individual characters to print. The characters must be positioned exactly within the form window.
- the individual colored partial images must be printed congruently in order to produce a multicolor image. All of this places high demands on the mechanics.
- EP 05238 0 describes a printing device in which a plurality of partial images of different colors are generated in succession and spaced apart on a photoconductor belt.
- the drawing files are opened individually on a printed part transmit a sheet-shaped recording medium, the recording medium being repeatedly guided past the url so that the partial images are re-printed as congruently as possible.
- the distance between two successive partial images is equal to the circumference of the rolls on which the photoconductor belt runs, or a multiple thereof, the individual rolls each having the same circumference.
- An uneven rotational movement for example as a result of an eccentricity of the roller axes, then has the same effect on all the partial images, so that the partial images which are overprinted congruently result in a full-color image without color errors.
- slip can occur between the drive rollers and the photoconductor belt. That the unrolled circumference of the drive roller at one turn is longer than the distance by which the photoconductor belt moves forward.
- the mechanics at the transfer points can change.
- the slip between the photoconductor band and the drive rollers is not constant, but can be caused by external influences such as Change temperature or humidity or due to aging.
- the changes in the mechanics at the transfer points are also dependent on external influences. These changes are difficult to determine. If, due to a slip or a change in the mechanics, the toner images can no longer be printed precisely on the form, this is often noticed only late and leads to rejects.
- DE 198 21 218 shows a printing device in which the different partial images are to be re-printed congruently on a transfer belt.
- several marks are arranged on the transfer belt, the passage of which is detected by a sensor.
- the detection signal of the marks is kept to a line synchronization signal in a fixed phase relationship. This requires a considerable circuit outlay ⁇ .
- Another printing device in which differently colored partial images are overprinted congruently is known from DE 198 06 551.
- a mark is printed on a paper web as a recording medium for each partial image.
- the reflectivity of the congruently printed marks is measured to check the alignment of the individual partial images to one another.
- the control of the individual printing units is regulated on the basis of this result of the check.
- This printing device also requires a considerable amount of circuitry. Precise printing in a form window cannot be achieved with this known printing device.
- the front edge of a sheet-shaped recording medium is detected by a sensor and the feed of the recording medium is controlled as a function of this detection.
- EP 0 281 055 discloses a printing device in which a position transmitter for a drum is provided. This printing device can also be used only for sheet-like recording media.
- the task is solved by an electrographic printing device with at least one printing unit with a toner image carrier, on the circumferential surface of which toner can be applied in accordance with an image-like distribution, the toner image carrier being a photoconductor, the outer circumferential surface of which can be charged with a latent charge image is, and has a transfer belt onto which the toner present on the photoconductor can be transferred at a first transfer printing location, a carrier material is guided past the transfer ribbon in such a way that the toner arranged thereon can be transferred to the carrier material at a second transfer printing location, along a circumferential section of the
- a printing device for generating the toner image is arranged on the photoconductor, which prints at least one mark on the photoconductor, at least one sensor is arranged on the transfer belt, which detects the passing of the mark, and a controller controls the running time of the mark from the time of
- the mark moves in the steady state from the time of detection to the time of transfer printing at a constant speed. Therefore, the time it takes for the toner image to be printed on the carrier material can be determined from the transit time. If, as a result of a change in the slip, for example due to a change in the ambient temperature, the pressure offense deteriorates, this change in slip also causes a change in the running time, which is monitored by the control. This indirectly detects a change in slip and the printing process can be controlled accordingly. For example, the transport of the carrier material can be controlled depending on the running time, for example by stopping the printing operation or by adjusting the transport speed.
- the transit time is compared with a predefined setpoint value, when it is exceeded or undershot, a signal is generated. If there is a deviation from the specified target value, the slip has changed or changes have occurred in the mechanics.
- the transport of the band-shaped carrier material can be controlled.
- the operation of the printing device can be interrupted in an exemplary embodiment of the invention. This will avoid printing scrap.
- the basic time required for the toner image applied by the printing device is determined in one measuring process in order to be printed at the second transfer printing location.
- the mentioned solo time is then determined on the basis of the base time.
- the target time can be 98% of the basic time. If the running time of the brand coincides with the target time in this case, it is ensured that the toner image is printed exactly on the carrier material at the desired location.
- the basic time is determined again when the signal occurs.
- the signal is generated when the running time deviates from the target time. This means that the base time has changed and the toner images are no longer printed on the substrate at the desired location.
- the basic time must therefore be determined anew and the transport of the band-shaped carrier material must be controlled in accordance with the changed slip. For example, the time between the generation of the latent image and the start of the transport of the carrier material can be adapted to the changed basic time.
- the sensor is preferably arranged near the second transfer printing point. Then the deviation of the transit time from the Bottom time especially small. This allows the toner image to be placed very precisely on the carrier material.
- a further development is characterized by the fact that the printing device has at least one image generation unit for generating a latent charge image on the photoconductor and at least one developer station that colors the charge oil with toner. This enables a uniform print image with a high resolution to be achieved.
- the printing device can also have several developer stations, which enables multicolor printing.
- a second printing unit for generating a toner image is provided on the side of the carrier material facing away from the first printing unit. In this way, duplex printing is possible, in which case both sides of the carrier material are printed simultaneously.
- the electrographic printing device has at least one printing unit with a toner image carrier, on the circumferential surface of which toner can be applied in accordance with an image-shaped distribution, the toner image carrier having a photoconductor, the outer circumferential surface of which can be charged with a latent charge image, and a transfer device.
- a carrier material is guided past the transfer belt in such a way that the toner arranged thereon can be transferred to the carrier material at a second transfer printing location, along a circumferential section of the photoconductor

- successive toner images can be re-printed congruently on the transfer belt.
- the circulation time of the mark is determined by the control on the basis of the detection of the passage of the mark on the sensor, the circulation time also changing when the slip or the length of the transfer belt changes.
- a change in slippage or a change in length of the ribbon is recognized, and the printing process can be controlled depending on the round trip time.
- the slip itself or the length of the transfer belt is not determined, the toner images can be arranged precisely on it.
- the time between the application of two successive toner images to the photoconductor is preferably determined on the basis of the round trip time.
- the photoconductor and the transfer belt run at the same, constant speed. In this way, the toner images can be placed particularly easily on the transfer belt.
- the orbital period is determined in one vormmeßvorgang.
- a turnaround time is available for the subsequent printing processes, on the basis of which the time between the application of two successive toner images to the photoconductor belt can be determined.
- a measuring process is carried out in parallel with each printing process. The printing device can thus be controlled particularly quickly and precisely.
- the transfer belt In a collecting mode, the transfer belt is repeatedly passed the first transfer printing point, and each time it is passed again, a toner image on the transfer belt is then transferred to the previous toner image. In this way, toner images can be superimposed particularly easily. A rhyme The transfer belt should be pivoted away from it.
- the transfer belt is pivoted away from the carrier material every time it passes by, so that contamination of the
- Carrier material and smearing of the toner images on the transfer belt is avoided.
- a further development is characterized in that, on the basis of the round trip time, the time between the application of two successive toner images to the photoconductor is set in such a way that they are overprinted congruently when the transfer belt passes the first transfer point.
- the transfer belt runs at a constant speed, and a change in the round trip time then means that the length of the transfer belt has changed. So that the toner images can be re-printed congruently, the time between the application of two successive toner images to the photoconductor must be changed.
- the mark can be fixed on the transfer belt.
- a reflective plate can be glued or riveted onto the transfer ribbon, or the mark can be a slit in the transfer ribbon. This ensures a long life and high accuracy in determining the round trip time.
- a reflex sensor is provided as the sensor, which detects the passing of the toner mark. This results in a simple structure.
