Definitions

  • the present invention relates to a circuit board for a printer cartridge, a printer cartridge with such a circuit board and a printing system.
  • Modern printing systems have printer cartridges that have memories and / or control chips or that are set up to communicate with memory and / or control chips.
  • printer cartridges of this type usually have a circuit board which allow interfaces or contact surfaces to establish an electrically conductive connection to the printer.
  • the function of such a printing system is dependent on the proper supply of the printing system with printing medium that is stored in the printer cartridge.
  • the printer cartridge regularly has a septum for this purpose.
  • the septum serves as a seal for the printer cartridge as long as it has not been inserted into the printer of the printing system.
  • the septum is usually pierced by a cannula, with which print medium can be delivered from the printer cartridge to the printing system.
  • This opening of the septum has proven to be a source of error in numerous pressure systems.
  • a precise alignment of the printer cartridge in relation to the printer - and thus to the cannula - cannot be guaranteed during the insertion process.
  • the printer cartridges used are not sufficient from a possibly existing management system of the Printer out and / or the user tilts the printer cartridge when inserting. This is made more difficult by the fact that the printer cartridge is usually inserted into the printer by inexperienced users and the insertion process is only carried out very sporadically, namely usually only when the print medium of a printer cartridge is used up.
  • the actual insertion process is extremely short in duration, so that the average user, who is also unaware that the goal of the insertion process is to pierce the septum, often inserts the printer cartridge in a manner that does the septum is not pierced.
  • the pressure systems known in the prior art still lack a control function for checking that the septum has been properly pierced. This often leads to malfunctions of the printing system - despite a new printer cartridge being inserted - since the print medium cannot be provided from the print cartridge.
  • the present invention is based on the technical problem of specifying a circuit board for a printer cartridge, a printer cartridge and a printing system, which enable reliable operation of a printing system, in particular making it possible to check that the septum has been properly pierced.

  • Such an arrangement of at least one area of the control contact area below the second row of contact areas of the first group ensures that when the printer cartridge is inserted into the printer, the control contact area is contacted as the first contact area by the contacts on the printer side. Since this control contact surface is connected to the first storage unit and / or to a second storage unit of the board, a check of the penetration of the septum and the result of the check in the first and / or the second storage unit can be carried out during the insertion process get saved.

  • Such a horizontally spaced arrangement of at least two control contact surfaces also advantageously leads to the fact that a tilted insertion of the printer cartridge into the printer can be detected. This is the case, for example, when both control contact areas are at the same height and the first control contact area is contacted during insertion 17 before contact is made with the second control surface. This is even more preferably the case when the two control contact surfaces are arranged adjacent to the contact surfaces of the second row, which are set up for applying a higher operating voltage. If only one pair of the two adjacent control surfaces is contacted at the same time by a printer-side connection in such a constellation, this is a sign that the printer cartridge has been inserted at an angle.

Abstract

L'invention concerne une carte (1) destinée à cartouche d'imprimante et comprenant une première unité de mémoire, un premier groupe de surfaces de contact (T1-T9) et au moins une surface de contact de commande (2). Au moins trois des surfaces de contact du premier groupe de surfaces de contact (Tl-T9) sont reliées à la première unité de mémoire. Les surfaces de contact du premier groupe de surfaces de contact (T1-T9) sont disposées en au moins deux rangées (4, 5) comportant chacune au moins deux surfaces de contact. La deuxième rangée (5) est à une distance (dy) de la première rangée (4) et est disposée au-dessous de la première rangée (4). Au moins une zone de la surface de contact de commande (2) est disposée au-dessous de la deuxième rangée (5) et la surface de contact de commande (2) est reliée à la première unité de mémoire et/ou à une deuxième unité de mémoire.
