Definitions
- the present invention relates to an apparatus for refilling an ink cartridge for an ink jet printer according to the preamble of claim 1.
- the present case is about the refilling of an ink cartridge for an inkjet printer with ink. It is to distinguish between cartridges with integrated printheads on the one hand and cartridges with a dockable to the ink supply port of an ink jet head Tintenauslouö réelle.
- the aforementioned printheads include a plurality of very fine jet nozzles through which the ink is transferred to a print carrier. In the case of multi-color ink cartridges, a predetermined number of jet nozzles are assigned to a predetermined color.
- a wick is usually arranged therein, which is in fluid connection with an ink storage element arranged inside the ink cartridge and consisting of absorbent material.
- the aforesaid nozzles are directly in fluid communication with the ink storage element disposed within the cartridge.
- the ink storage element is made of either fibrous material or foam. Since this is a known measure in this regard, a more detailed description of the same is unnecessary here. Also, there are now other "negative pressure generating mechanisms" which ensure a metered supply of ink to the nozzles or to the ink outlet opening. In the following, they should also fall under the term "ink storage element".
- Cartridges with integrated print heads must be broken up and resealed very carefully to refill with ink. The effort is correspondingly large and not profitable for cartridges with small quantities.
- syringe refill systems are known for cartridges of the aforementioned type, by means of which an original cartridge can be refilled.
- the corresponding sets include a drill, a hot glue gun, at least four
- Syringes with cannula, ink, conventional rubber band and closure means are commercially available. However, they are characterized by unwieldiness and disproportionate effort in terms of material and tools.
- Cartridges with integrated printhead are very expensive to buy in the so-called recycling market. They are then mechanically opened, cleaned and replaced with a new ink storage element, e.g. Sponge od. Like. Provided. Subsequently, replacement ink is filled and the cartridge closed again. All this work can only be done at a specific refill company, not the user himself.
- the present invention has the general object to provide a device for refilling an ink cartridge for an inkjet printer, which in their user friend is much improved, so not only easy to manufacture and very easy to use, so that it can be controlled by the end user without further ado, but also characterized by the fact that accidental, incorrect filling of the ink cartridge is prevented.
- the device should be equally effective for cartridges with integrated printheads and cartridges with a dockable to the ink supply of an ink jet head Tintenauslouötechnisch.
- the object is achieved by a filling device for refilling an ink cartridge for an inkjet printer, with a printhead comprising nozzles or with an ink outlet openings which can be coupled to the ink supply of an inkjet head, either the nozzles of the printhead being able to be coupled directly or coupled to the ink supply of an inkjet head Tintenauslass- opening this via a wick with an arranged within the ink cartridge and, for example, absorbent material or a negative pressure generating mechanism comprehensive ink sp eicher element in fluid communication, comprising an ink-filled container having an opening in which the ink submerged and wick contactable with the ink storage element of the ink cartridge, the ink cartridge refilling device comprising an information processing unit configured to i to enter into operative connection with an information processing unit provided on the ink cartridge or to read and / or change information provided on the filter cartridge.

- Identification or as a resistance value of a resistance bridge The detection of the information provided on the filter cartridge information in the form of a bar code can be easily done by widely used devices. Numerous advantages in terms of the ability to detect the use of barcodes also result from the fact that a barcode can be detected easily, quickly and without physical contact, both in the production process and in logistics and sales engineering steps. These advantages can also be cited for the provision of information as an RFID tag identifier, since both RFID tag identifiers can be read out easily and also without contact via RFID tag readers which are widely used in the industrial as well as sales area.
