Abstract

Les réservoirs (11, 12) pour dispositifs d'impression, qu'il s'agisse de réservoirs d'encre, de cassettes à ruban encreur ou de réservoirs de toner, présentent un dispositif de stockage électronique (14) sous forme d'un chip, dans lequel sont mémorisées des informations sur l'état actuel du remplissage du réservoir et/ou d'autres données relatives au fonctionnement de l'imprimante, par exemple des dates de fin de validité du fluide d'impression. Reservoirs (11, 12) for printing devices, both ink tanks, ink ribbon cassettes or toner reservoirs have an electronic storage device (14) as a chip in which are stored information about the current state of filling of the reservoir and / or other data concerning the operation of the printer, e.g., end dates of validity of the printing fluid. Une commande centralisée (16) du dispositif d'impression permet de détecter l'état de consommation en fluide d'impression et de le transmettre au chip (14). A centralized control (16) of the printing device can detect the state of printing fluid consumption and transmit it to the chip (14). Le chip associé au réservoir réalise le comptage de la consommation jusqu'au moment où la réserve en fluide d'impression (liquide encreur, ruban encreur, toner) est épuisée, ce qui nécessite le changement de réservoir. The chip associated with the tank carries out the counting of the consumption until the reserve printing fluid (liquid ink, ink ribbon, toner) is exhausted, which requires the tank change. On ne peut procéder à une nouvelle programmation du chip et, par voie de conséquence, à un nouveau remplissage du réservoir. One can not make a new program the chip and, consequently, a new refueling.

Description

Arrangement for pressure devices for monitoring print medium containing reservoirs.

In office printing devices, be it text systems or simple printing systems that work in conjunction with tionsendgeräteh communication, various Druckprin¬ come ciples apply. This pressure principles are tendruck eg Tin¬, thermal transfer printing, matrix printing or letterpress type with slices and electrophotographic printing. Al len these principles have in common that a container of stored products contained in a character-dependent pressure medium is applied to a recording medium. The Vorrats¬ container - be it writing fluid contained Be¬ ratios, ribbon cartridges or toner containers - are usually interchangeable in holders of printing devices attached. You can designed as Einwegebehälter that are filled at the factory and exchanged as a whole according to consumption of the media.

Such a reservoir for ink printing devices are known for example from DE-PS 26 10 518 Farbbandkas¬ cassettes from DE-PS 32 14 548th

To ensure a secure printing, it is common to monitor the supply of pressure medium in the reservoirs. This monitoring is particularly important in Tin- tenschreibeinrichtungen necessary where the Schreib¬ head consists of a mosaic write head in which a plurality of write nozzles are arranged. Through the nozzles in this writing runs in the write operation contraction processes, such a stylus supplied independently with writing fluid from an ink reservoir. Air penetrates into the writing nozzle one, it requires special rinses to remove the air. Such Einrich- obligations of monitoring the ink is depleted in ink writing devices, for example, are be¬ known from DE-PS 26 17 730th

Ink printing devices are furthermore particularly sensitive with regard to the composition of the lent Tin- used tenflüssigkeit \ A not matched to the ink printing system, ink may lead to destruction of the Druck¬ head. For this reason it is necessary to prevent waste ink reservoir to be filled with ink composition again unknown Zu¬ in an uncontrolled manner, for example by other manufacturers.

The same applies to ribbon cartridges every kind, whether here may uncontrolled refilling with the Farbbän- in which the specification of the ribbon, for example, is not respected in terms of thickness and layer structure, leading to disorders of the printing operation.

Particularly sensitive to the composition of the printing medium are on the principle of electrophotography working pressure or copy service in which a charge image, for example, is colored with the aid of a developer mixture of carrier particles and toner particles. The inked charge image is transferred to a transfer printing on paper and fixed in a fixing. When developing resistant toner is consumed, the storage containers from Vor¬ the developer station is supplied. Ins¬ particular in electrophotographic printers low power, such as office printers, interchangeable To- are nervorratsbehälter provided. Toner will be false Zu¬ fed composition, there may be a significant Be¬ einträchtigung the printer operation come.

In that regard is described below with each type of printing means printing means including copying the verstan¬ in which a printing medium is a character-dependent applied to a recording medium. 1 object of the invention is therefore to provide an arrangement for printing devices, with which it is possible on the one hand, easy to grasp er¬ the supply of pressure medium, on the other hand possible unauthorized How-

5 to prevent derfüllen spent reservoir, or to recognize such rec 'Grid monitoring meets the reservoir.

This object is achieved ches 10 in an arrangement of the type called ge according to the features of the first Patentanspru-.

Advantageous embodiments of the invention are gekennezeichnet in the subclaims.

I 5 In accordance with the invention, a storage container for equipment Druck¬ is an electronic storage device in the form of an integrated circuit (chip) is assigned, in a detection arrangement available information about the current fill status of the reservoir or

20 other relevant for printer operation status data of the print media are stored. These status data could be information about the expiration date of the media.

25 By this arrangement, it is easily possible to detect operation of the fill level of the reservoir during the Drucker¬. Falling short of a Mindest¬ stock of print media can be detected in time. Upon reaching the reservoir end or after falling below

- 50 a minimum depleted can trigger a warning signal via the control arrangement of the printing device and displayed on a display and it is possible to Druckbe¬ drove to block.

* 55 The fact that the electronic storage device is constructed in the form of an integrated circuit so that the electronic memory device can not be programmed again after reaching the stock end zu¬ reliably an illegal refilling spent Vor¬ is bins prevented or can such refilled reservoirs are clearly recognized.

In an advantageous embodiment of the invention ent electronic storage means holds a pre-adjustable in its basic setting timer whose Zähl¬ stand, starting from the basic setting corresponding to the current shelf-life of the print medium is changed irreversibly. Damage to the printing device, for example due to old or writing liquid toners are da¬ prevented reliably.

An embodiment of the invention is illustrated in the drawings and will hereinafter be described in more detail for example be¬. Show it

1 shows a block diagram of the inventive arrangement in a multi-color ink jet print device and

2 shows a schematic representation of the construction of an arrangement for constructive Auf¬ monochromatic mode.

an ink mosaic printing head 10 along a recording medium is in a device not shown here in detail Tintendruck¬ by means of a motor means in the printing operation is moved line by line. In the Tintenmo¬ saikdruckkopf is a Mehrfarbentintenmo- saikdruckkopf the example according to the bubble principle works and which is supplied with writing fluid from two ink reservoirs 11 and 12 via a supply system Tintenver¬. The ink containers 11 and 12 can with the ink print head ei¬ ne structural unit form or they are arranged to be stationary and connected to the ink mosaic printing head 10 through a flexible conduit. The ink reservoir 11 in its constructive structure corresponds to that presented in Figure 2. ones shown, ink reservoir, it comprises two flexible storage bubbles for receiving the Tintenflüs¬ sigkeit which are connected via respective connecting elements 13 with the supply system for the nozzle elements of the write head. Filled the storage bubbles of the ink reservoir 11 with black ink, over the Tiπtenvorratsbehälter 11 is in multicolored Tintendruck¬ facilities another ink reservoir arranged ange¬ 12 having three storage bubbles with color inks (magenta, cyan, yellow) are filled are. in pure

Black / White-operation is a supply of Tinten¬ print head 10 solely from the ink reservoir 11, only in color mode, ink from the Tintenvorratsbe¬ hälters 12 removed.

connected to the ink reservoirs 11, 12, for example by gluing or casting, is an electronic memory 14 in the form of an integrated circuit (chip), which may have a structure as found, for example in so-called Telefonkar- th application in which the after plugging card into a pay phone charges by bit¬ wise deleting a Spei¬ contained in the chip card will be debited cherleiste. The electronic memory 14 is connected via tendruckeinrichtung not shown lockable connecting elements and a line 15 to the central controller 16 of the Tin¬.

Each of the connected to the ink reservoirs chip 14 serves to store, in a storage area of ​​the current state of filling the ink storage bubbles of the respective Tintenvor¬ rats container. For this purpose, each chip for each given bladder includes a memory strip 17, for example, can also be embodied as electronic counters and their count state or slip state of the filling corresponds to the associated storage bubble. Thus, the ink reservoir 11 includes brakes with two Speicherbla¬, two-rail 17, the ink tank 12 with three storage bubbles three-rail 17. The Funk¬ tion of this common-rail or counter is explained er¬ later. In addition to these so-called common rail 17, timer 18, that timer is provided. The timer 18 can also be embodied as an electronic counter. The timer 18 contain information about the expiration time of the ink liquid. They are activated upon initial insertion of the ink reservoir or during production, that they begin to run from that date and count up, with their count corresponds to information about the shelf life of the ink liquid. The timers are an option, and they may consist of a chip 14 in the inte¬ grated power source (voltage source) which is not shown here, to be independent of the mains supply with ink.

Also located in the chip, a read only memory 19 for receiving an ink reservoir kennzeich¬ Neten codes. This code is tenvorratsbehälters burned in the production of Tin¬ in the ROM. Its content is checked in the ink jet print device on the installation of the ink reservoir. Only after a positive check the printer operation will then control the release Zentral¬ 16th The read only memory is formed as a memory, the coding for the first-time programming can not be altered. The code can this information represents the nature and content of the ink reservoir whose Herstel¬ are perishable and expiration date, etc. When locking the Tin¬ tenvorratsbehälter in the holder of the Print Setup is then checked by the central controller 16 of this Code.

The central controller 16 is microprocessor-controlled and includes a CPU such as a microprocessor 80,199th via a data bus system BUS connected to the Zen¬ traleinheit is read-only memory, a character generator ZG in the form of a Fest¬, the generier- bare Zeicheπfor includes using mosaic pressure s. Furthermore, a writable non-volatile memory (EE-PROM) SP keeps its memory state even when beibe¬ abge¬ power is on. The memory SP is used inter alia as Zwischeπspei- more and contains a number of common-rail 17 corresponding number of memory areas SP1 to SP5, which cooperate in the manner described later to the memory strips 17th The memory SP may also be formed as Pro¬ program memory for the control program of the printing device.

further coupled to the bus system is a one-block output SCA. It is a usual control in Drucker¬ universal block that the Kom unika- tion of the printing device with the interface 20 on the printing device Da¬ teneingang accomplished. This one-output port SCA also has the task of Um¬ setter for converting parallel data to serial data.

Another RAM memory, which is also connected via the BUS system with the input and output module SCA, serves as an intermediate storage for the interface 20 via the incoming data before post-processing in the printer controller sixteenth

The actual communication between the Zentralsteue¬ tion 16, the ink head 10 and the electronic manuals Spei¬ 14 via a designated TI-ASIC Bau¬ stone. It contains a corresponding logic structure to the bus the central controller 16, the drive data for the Tin¬ tenmosaikdruckkopf 10 to assume parallel and control signals 10 set umzu¬ in the presence of the individual nozzles of the head.

The entire arrangement operates according to the following principle: The ejected ink printing devices in the operation amount of ink can be detected by counting the individual droplets ejected. Each droplet has both an be¬-determined constant volume, so that it is known how many droplets example tenvorratsbehä with the contents of a memory of the bubble Tin- 'can be generated lter. The mosaic printing head ejected from Tinten¬ droplets of each color are thereby detected by the detection arrangement of the central controller 16 in the printing operation and a function of the fixed set consumption in the electronic Speicher¬ device 14 stored information about the Füllzu¬ state of ink reservoir adapted. This matching can for example take place in that the first filled-rail is extinguished 17 bit by bit according to the overall consumption.

The function of the arrangement in detail:

In the preparation of the ink reservoir when inserting the electronic storage element (chip 14) is activated in the ink reservoir the chip. The chip 14 is arranged in the timer 18, which may be of a ver¬ provides netz¬ independent power source not shown here, for example, has a basic adjustment of its Zäh- coupler, whose count corresponds to the permissible storage time of the ink liquid. This timer (timer) 18 is activated in the preparation of the ink reservoir and the assembly to the electronic storage element fourteenth If the timer has expired, ie a count on the line 15 is located at the contacts on the container surface at, which ent speaks of information "ink end". This information is queried via the TI-ASIC chip and, for example, formed on the printing device in the form of a lamp 21 warning device activated. Simultaneously recording the printing operation is stopped unter¬. It is however also possible to arrange a separate Warn¬ lamp or a separate display means for indicating the exceeding of the expiration date of the ink container immediately.

With initial insertion of the ink reservoir 11, 12 in the ink printing device the basic adjustment of the timer number in the chip 14 is set in the unit liquid on the operating time of the Tinten¬. This service time may be the reservoir is less than the basic setting at antecedent corresponding long-term storage of the Tinten¬. After expiration of the timer is - as already described - via the warning lamp 21 or a corresponding display "ink end" is displayed.

In the write operation of the TI-ASIC detects the actuation pulses for the individual nozzles of the ink mosaic printing head 10, and thus the number of individual surfaces ejected Tröpf¬. the ausgebil¬ as a counter Deten memory areas SP1 to SP5 are activated via the software. The counter SP1 to SP5 are the individual ink bubbles and hence associated with the various printing inks. For meters han¬ it delt by circulating counter who return after reaching a be¬ voted count to their normal position and start counting again. The counter capacity ent speaks tentröpfchen a certain number of eg 10,000 Tin-. When resetting the counter, that is, after each counting 10 000 ejected Tintentröpf¬ each of ink chen (color) is deleted at the reservoirs bitwise via the block TI-ASIC, the corresponding allocated memory block 17 of memory elek¬ tronic fourteenth That is, the count of one of the strip 17 Speicher¬ associated counting means of the chip 14 is correspondingly changed starting from a corresponding to the filled condition of the Vorratsbehäl¬ ters preset basic count the consumption of the ink liquid. This change is irreversible, that is, after the counter or "debiting" the bits on the data strip 17 reprogramming is not possible. Both the counter in the unit SP1 to SP5 and the counter in the chip 14 (data block 17) are permanent, meaning that they are when the power source of the Tintendruckeinrich- tung not reset.

The consumed during cleaning procedures amount of ink is chen also be included in the listing of the number of ejected Tintentröpf¬.

If the count reaches into the chip 14 a, such as a minimum supply quantity corresponding counter state (fully abge¬ booked bit register 17), this count is detected by the Bau¬ element TI-ASIC and activates a warning device, for example in the form of a lamp 21st This can be done by a flashing signal is output through the lamp 21st With the food holding at this point in the Tintenvorratsbe¬ containing minimum ink supply, the write operation can still get a certain time upright. After reaching a count of the ink end, ie the complete consumption of ink corresponding to the ink supply (taking into account a Sicherheitsre¬ serve), a further Drucker¬ operation on the block TI-ASIC prevented and the lamp 21, for example, then switched on permanently can be, this ink end displayed.

As already described, the electronic memory is designed such that reprogramming is not also possible. If the waste ink reservoir in an inadmissible way again filled with ink, so the electronic memory 14 remains in its the "ink end" ent speaking state. Therefore, upon insertion of such a wie¬ dergefüllten ink reservoir in the direction 21 Tintendruckein¬ ink end is indicated by the block TI-ASIC and the warning device and the drive Druckbe¬ prevented. The inventive arrangement has been written above with reference be¬ a storage container for an ink printing device. However, it can also be applied to the ink ribbon cartridge of any kind, be it ribbon cartridges with ther- mofarbbändern for thermal transfer printing devices or ribbons for "impact printer. With ribbon cartridges a chip is analogous to ink reservoirs in a here not dar¬ made way to the ribbon cassette 14 (electronic storage device ) secured to the corresponding construction described. During the Schreibbetrie¬ bes a continuous transport monitoring of the ink ribbon, for example, performed by a device according to the DE-PS 32 14 548. Depending on the number of printed individual points for mosaic printing devices or the printed number of characters in type printing devices, the ink ribbon in the ribbon cassette of the Vorrats¬ coil is moved to the reel. with the inventive arrangement of ribbon consumption is detected by the electronics of the printing device on the drive pulses of the printhead and d he electronic storage device 14 communicated to the ink ribbon cassette. The chip 14 (electronic storage device) counts the consumption until the Farb¬ tape supply is exhausted the extent that the ink ribbon cassette should be replaced. The consumption state of ink tape cassette can always tralsteuerung in printing operation by the Zen¬ be queried 16th Shows the count in the chip 14 the consumed state of the ink ribbon cassette on, is interrupted by the printer electronics in the described manner another print output and set a corresponding error message.

The arrangement described can contact an¬ even with elektrophoto- graphic or magnetic printer or copier. Modern printers or copiers, which are designed for the power set in the office, have interchangeable Toner¬ reservoir, which will be replaced in its entirety by a depleted toner (DE-A-GM 87 05 870). Often a replacement of the entire developer station of Fotoleitertrommεl finally ein¬ provided. Here, too, an electronic memory device can be arranged in the described manner to the container which cooperates with the central controller of the electrophotographic copying machine or Druck¬. As it is known, the amount of toner wie¬ average for the coloration of a La¬ dung image is necessary, for example, omits the number of revolutions of the charge image carrier or from measurement of Einfärbegrades of characters via an optical Sen¬ sor toner consumption determined. The electronic Spei¬ chereinrichtung (chip) counts the consumption of toner until the toner supply is exhausted the extent that the Tonervorratskas- must be replaced sεtte. The consumption state of the toner cartridge can be requested any time during the printing operation by the central controller. Displays the count in the chip the used state of the supply cassette, another printing operation is inhibited and activated eg fourth a corresponding display on a display of the central controller.
