Definitions

  • the invention relates to an office machine printer of the facsimile, photocopier, computer type, for example, the printing of which can be carried out by thermal transfer, by ink jet or by laser, with a consumable of the ink ribbon type, ink or toner.
  • the printing consumable is contained in a reservoir (roller, cartridge), intended to be introduced into a receiving housing provided in the printer.
  • a control lamp provided on a printer-user interface, lights up to inform the user that it is necessary to replace the tank.
  • Such a control device therefore does not make it possible to foresee a subsequent need for consumables, and the user can be caught off guard and run out of consumables in reserve.
  • EP 0 551 752 discloses a printer assembly with a consumable reservoir, a control unit, a memory and an interface. Calculation means determine the balance of consumable remaining in the tank from the measurement of consumption of the consumable.
  • Patent EP 393 627 describes a laser printer assembly with a removable cartridge comprising a memory containing information on the drum.
  • US Pat. No. 5,283,613 discloses a printer assembly and its consumable reservoir for an office machine, comprising a central control unit and means for controlling the content of the consumable reservoir associated with memory means containing a balance of consumable account.
  • Said control means comprise a central unit / memory means interface associated with means for managing said memory means integrating means for determining the content of the consumable reservoir.
  • the consumable account balance corresponding to the printing capacity of the tank, is represented by a number of images remaining at print and decrease the number of images printed during successive image prints.
  • the invention aims to overcome this drawback.
  • the invention relates to an assembly of the type defined above, characterized in that the management means comprise means, in cooperation with the central unit, for calculating flow rate to evaluate the consumption of consumable as a function of an estimated quantity of printing, and calculation of the remaining consumable account balance, the memory means comprise an electronic chip and the central unit / chip interface comprises connectors by which the chip can be connected to the central unit.
  • the user can be informed at any time and with reliability of the value of the content of the consumable reservoir, the consumable account being debited in proportion to the consumption of consumable precisely evaluated during printing.
  • the memory means contain means for authenticating said consumable.
  • the consumable account available to the user is materialized on a medium.
  • said chip is carried by a card which is detachably attached to the consumable reservoir and to be introduced into means for receiving the printer.
  • said reception means may comprise a sliding card support plate relative to a fixed connector support gantry and integral with the printer, or else a smart card reception slot, carrying said connectors on the one of its internal faces, the chip being intended to be connected by sliding.
  • the chip is permanently fixed to the consumable reservoir, and the connectors are mounted on the internal face of a cover of a housing for receiving said consumable reservoir.
  • the chip can also act as a key for locking / unlocking the printer, authorizing or not its operation.
  • the memory means and the central unit-chip interface can respectively comprise an electronic chip and a device intended to connect the chip to the central unit by a contactless link.
  • the laser printer 1 for an office machine, here a photocopier, incorporates a central control unit 2, in this case a microprocessor, connected to a printing unit 3 comprising a printing member 4 on a paper printing medium for example, and a consumable reservoir 5, in this case, a toner reservoir for laser printing intended to supply toner to the printing member 4.
  • a central control unit 2 in this case a microprocessor
  • a printing unit 3 comprising a printing member 4 on a paper printing medium for example, and a consumable reservoir 5, in this case, a toner reservoir for laser printing intended to supply toner to the printing member 4.
  • the reservoir 5 is associated with memory means comprising an electronic chip 9 with memory carried here by a card 7, of the type and format telephone card, but which could be of another form.
  • the consumable card 7 is detachably attached to the reservoir 5 as commercially available, and is to be inserted into the printer 1.
  • the chip 9 contains in memory a consumable account balance, in other words a number of consumable units contained in the reservoir 5, a unit corresponding to a number of ink dots to be printed, as well as consumable authentication data in particular to refuse the card of an inadequate consumable.
  • the interface 8 microprocessor / chip 2/9 comprises a device 20 for receiving the smart card 7 comprising a card support tray 21 which can slide between an open position outside the printer and a closed position in the printer, relative to a gantry 22 supporting connectors 23, fixed and secured to the printer. In the closed position, the face of the plate 21 intended to carry the consumable card 7 is opposite the face of the gantry 22 carrying the connectors 23.
  • the user can insert the tank 5 into a receiving housing provided in the printer 1, and place the consumable card 7 on the open support tray 21 before closing it by sliding it into the printer.
  • the chip 9 is positioned on the connectors 23 of the gantry 22, the chip / microprocessor 9/2 link is thus established.
  • the reservoir 5 supplies the printing member with consumable 4.
  • the computer 10 evaluates the consumption of consumable due to printing by determining a number of units of consumable to be debited according to a approximate number of ink dots printed.
  • microprocessor 2 reads in the chip 9, using the interface 8, the value of the previous balance of the consumable account, then transmits it to the computer 10.
  • the filling rate thus evaluated corresponds to the quantity of consumable remaining to be consumed in the tank 5.
  • the chip card 7 is to be inserted into a reception slot designed in the printer, the connectors 23 being mounted on one of the internal faces of the slot so that the chip 9 is also connects by sliding, when it is inserted into the slot.
  • the chip 30 is permanently fixed to the consumable tank 31, using a fixing support, and connectors 32 for connecting the chip to the microprocessor are mounted on the internal face 33 a cover 35 for housing 34 for receiving the tank 31.
  • connectors 32 for connecting the chip to the microprocessor are mounted on the internal face 33 a cover 35 for housing 34 for receiving the tank 31.
  • the format of the smart card presented in the description above is that of the telephone card type, but it could as well be that of the SIM card type, or other.
  • the introduction of the consumable chip card into the printer authorizes the operation of the printer, the card playing the role of locking and unlocking key.
  • connection between the chip and the printer is made by contact using connectors intended for come into contact with the chip, one could also consider such a connection being made without contact, by electromagnetic link, using a contactless connection device.
  • the printer which has just been described is a laser printer.
  • calculating the number of consumable units consumed amounts to evaluating the number of ink droplets consumed and the number of ink droplets remaining to be consumed.
  • the printer could integrate a computer arranged to evaluate the respective consumptions of the various consumables, and the respective remaining quantities of consumables.
