Definitions
- the invention relates to a method for making reusable cartridges for photocopiers and laser printers, which are equipped with a photoconductor drum coated with an organic photoconductor and a charging and developer station, as well as with an inherently non-refillable neutron container and a non-emptying residual toner container.
- Disposable cartridges that are not reusable after they have used up the new toner they contain, since they do not offer any options for refilling new toner and removing residual toner, are used to a not inconsiderable extent in connection with comparatively small copying machines and laser printers. Their use is based on the consideration of keeping the amount of the toner supplied in the toner container so small that there is almost certainly no need for maintenance of functionally important parts of the cartridge. In other words, the toner is running low before the failure of important parts of the cartridge can be expected.
- the described method of operation has a lot to offer because it practically excludes the risk of device downtimes, for example because of a photoconductor drum that has become unusable, if a replacement cartridge is available.
- the concept described turns out to be less convincing, because the exchange of a used cartridge with one defective part against a new cartridge is no less expensive than the corresponding exchange with a cartridge, the only defect of which is that its toner has been used up.
- the invention is based on the object of showing a way which makes it possible to make disposable cartridges reusable with simple means.
- the new toner container is subsequently provided with a refill opening accessible from the outside of the cartridge and a lid serving to close this opening, and that emptying holes which can be closed by an adhesive strip or by plugs are incorporated in the residual toner container.
- the method according to the invention opens up the possibility of reusing commercially available disposable cartridges and in this way not only reducing the copying or printing costs, but also making a contribution to environmental protection by reducing industrial waste.
- Experiences gained from experiments have shown that it is regularly possible to refill commercial disposable cartridges two or three times without problems, the proportion of toner costs in relation to the other cartridge costs being very low.
- 1 is the housing of a cartridge for a copier or a laser printer, in which, in addition to a new toner container 2 and a waste toner container 9 at least one photoconductor drum coated with an organic photoconductor, a charging station and a developer station are accommodated.
- the top of the neutron container 2 is provided with a refill opening 3, which can be closed by a lid 4 with a handling tab 5.
- the lid 4 is preferably made of cardboard and is connected to the cartridge by means of an adhesive strip 6 forming a hinge.
- Adhesive strip sections 7 provided on both sides with an adhesive layer serve to lock the lid 4 in the closed position, in which the lid bears against a flat part 8 in the area of the ceiling or top of the neutron container 2.
- the size of the refill opening can correspond to the respective circumstances, i.e. in particular depending on whether toner powder or toner cartridges are refilled.
- the waste toner container 9 of the cartridge is provided with emptying openings 10 which, in the illustrated case, are formed by a row of holes which can be closed by a removable adhesive strip 11.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Wiederverwendbarmachen von Wegwerfkartuschen für Fotokopiergeräte und Laserdrucker, welche mit einer mit einem organischen Fotoleiter überzogenen Fotoleitertrommel und einer Lade- und Entwicklerstation sowie mit einem von Haus aus nicht nachfüllbaren Neutonerbehälter und einem von Haus aus nicht entleerbaren Resttonerbehälter ausgestattet sind.The invention relates to a method for making reusable cartridges for photocopiers and laser printers, which are equipped with a photoconductor drum coated with an organic photoconductor and a charging and developer station, as well as with an inherently non-refillable neutron container and a non-emptying residual toner container.
Wegwerfkartuschen, die nach Verbrauch des in ihnen enthaltenen Neutoners nicht wiederverwendbar sind, da sie keine Möglichkeiten zum Nachfüllen von Neutoner und Entfernen von Resttoner bieten, werden in nicht unerheblichem Maße in Verbindung mit vergleichsweise kleinen Kopiergeräten und Laserdruckern verwendet. Ihrem Einsatz liegt die Überlegung zugrunde, die Menge des im Tonerbehälter mitgelieferten Toners so klein zu halten, daß sich mit an Sicherheit grenzender Wahrscheinlichkeit eine Wartung funktionswichtiger Teile der Kartusche erübrigt. Der Toner geht mit anderen Worten zur Neige, ehe mit dem Ausfall funktionswichtiger Teile der Kartusche gerechnet werden kann. Die beschriebene Handhabungsweise hat auf den ersten Blick einiges für sich, weil sie die Gefahr von Gerätestillstandszeiten z.B. wegen einer unbrauchbar gewordenen Fotoleitertrommel praktisch ausschließt, falls eine Ersatzkartusche zur Verfügung steht. Beinäherem Hinsehen erweist sich die geschilderte Konzeption indessen als weniger überzeugend, denn der Austausch einer gebrauchten Kartusche mit einem defekten Teil gegen eine neue Kartusche ist nicht minder unaufwendig als der entsprechende Austausch mit einer Kartusche, deren einziger Mangel darin besteht, daß ihr Toner verbraucht ist.Disposable cartridges that are not reusable after they have used up the new toner they contain, since they do not offer any options for refilling new toner and removing residual toner, are used to a not inconsiderable extent in connection with comparatively small copying machines and laser printers. Their use is based on the consideration of keeping the amount of the toner supplied in the toner container so small that there is almost certainly no need for maintenance of functionally important parts of the cartridge. In other words, the toner is running low before the failure of important parts of the cartridge can be expected. At first glance, the described method of operation has a lot to offer because it practically excludes the risk of device downtimes, for example because of a photoconductor drum that has become unusable, if a replacement cartridge is available. On closer inspection, however, the concept described turns out to be less convincing, because the exchange of a used cartridge with one defective part against a new cartridge is no less expensive than the corresponding exchange with a cartridge, the only defect of which is that its toner has been used up.
Der Erfindung liegt als Konsequenz aus der geschilderten Überlegung die Aufgabe zugrunde, einen Weg aufzuzeigen, der es gestattet, mit einfachen Mitteln Wegwerfkartuschen wiederverwendbar zu machen. Zur Lösung der gestellten Aufgabe wird erfindungsgemäß vorgeschlagen, daß der Neutonerbehälter nachträglich mit einer von der Außenseite der Kartusche zugänglichen Nachfüllöffnung und einem zum Schließen dieser Öffnung dienenden Deckel versehen wird und in den Resttonerbehälter durch einen Klebestreifen oder durch Stopfen verschließbare Entleerungslöcher eingearbeitet werden.As a consequence of the above consideration, the invention is based on the object of showing a way which makes it possible to make disposable cartridges reusable with simple means. To achieve the object, it is proposed according to the invention that the new toner container is subsequently provided with a refill opening accessible from the outside of the cartridge and a lid serving to close this opening, and that emptying holes which can be closed by an adhesive strip or by plugs are incorporated in the residual toner container.
Das erfindungsgemäße Verfahren eröffnet die Möglichkeit, handelsübliche Wegwerfkartuschen wiederzuverwenden und auf diese Weise nicht nur die Kopier- oder Druckkosten zu senken, sondern durch Reduzierung von Industrieabfall auch einen Beitrag zum Umweltschutz zu leisten. Durch Versuche gewonnene Erfahrungen haben gezeigt, daß ein zwei- bis dreimaliges Wiederbefüllen handelsüblicher Wegwerfkartuschen regelmäßig problemlos möglich ist, wobei der Anteil der Tonerkosten im Verhältnis zu den sonstigen Kartuschenkosten sehr gering ist.The method according to the invention opens up the possibility of reusing commercially available disposable cartridges and in this way not only reducing the copying or printing costs, but also making a contribution to environmental protection by reducing industrial waste. Experiences gained from experiments have shown that it is regularly possible to refill commercial disposable cartridges two or three times without problems, the proportion of toner costs in relation to the other cartridge costs being very low.
Eine Kartusche, die nach dem erfindungsgemäßen Verfahren wiederverwendbar gemacht wurde, wird im folgenden anhand der beigefügten schematischen Zeichnung beschrieben.A cartridge that has been made reusable by the method according to the invention is described below with reference to the attached schematic drawing.
In der Zeichnung ist 1 das Gehäuse einer Kartusche für ein Kopiergerät oder einen Laserdrucker, in dem neben einem Neutonerbehälter 2 und einem Resttonerbehälter 9 zusätzlich mindestens eine mit einem organischen Fotoleiter überzogene Fotoleitertrommel, eine Ladestation und eine Entwicklerstation untergebracht sind. Der Neutonerbehälter 2 ist an seiner Oberseite mit einer Nachfüllöffnung 3 versehen, die durch einen Deckel 4 mit einer Handhabungslasche 5 verschließbar ist. Der Deckel 4 besteht vorzugsweise aus Pappe und ist an der Kartusche mit Hilfe eines ein Scharnier bildenden Klebestreifens 6 verbunden. Doppelseitig mit einer Klebstoffschicht versehene Klebestreifenabschnitte 7 dienen zur Verriegelung des Deckels 4 in der Schließstellung, in der der Deckel gegen einen planen Teil 8 im Bereich der Decke bzw. Oberseite des Neutonerbehälters 2 anliegt.In the drawing, 1 is the housing of a cartridge for a copier or a laser printer, in which, in addition to a
Die Größe der Nachfüllöffnung kann den jeweiligen Gegebenheiten entsprechend, d.h. insbesondere in Abhängigkeit davon, ob Tonerpulver oder Tonerpatronen nachgefüllt werden, gewählt werden.The size of the refill opening can correspond to the respective circumstances, i.e. in particular depending on whether toner powder or toner cartridges are refilled.
Um unerwünscht große Abmessungen des Resttonerbehälters 9 der Kartusche zu vermeiden, ist der Resttonerbehälter mit Entleerungsöffnungen 10 versehen, die im dargestellten Fall von einer Lochreihe gebildet werden, die durch einen abziehbaren Klebestreifen 11 verschließbar ist.In order to avoid undesirably large dimensions of the waste toner container 9 of the cartridge, the waste toner container is provided with emptying
