  • Patent number: 9033462
    Abstract: The case 22 of a waste ink tank 13 has ribs 51, 52 that partition the space between a waste ink inlet 36 and an air vent 33. Air passages 65, 66 that connect the waste ink storage spaces S1, S2, S3 partitioned by the ribs are formed at the top ends of the ribs 51, 52. Waste ink permeates all of a sponge 21 through the space between the ribs 51, 52 and the bottom wall 24. Because a path for air to flow to the air vent 33 is constantly maintained inside the case 22 by the air passages 65, 66, air is discharged from the air vent 33 as waste ink is introduced to the case 22. The strength of the case can therefore be increased without interfering with introducing waste ink to the case and absorption of introduced waste ink by the sponge.

  • Patent number: 9028039
    Abstract: An image forming apparatus includes a recording head, an ejection detector, a cleaner and cleaning ejection controller. The ejection detector has a droplet landing member disposed in an area in which the droplet landing member faces the head. The ejection detector detects ejection or non-ejection by detecting electric change caused by landing of the droplets on the droplet landing member. The cleaner cleans a droplet landing surface of the droplet landing member. The cleaning ejection controller controls the recording head to eject droplets on the droplet landing surface for cleaning the droplet landing surface before cleaning the droplet landing surface by the cleaner. A quantity of the droplets for cleaning the droplet landing surface is greater than a quantity of the droplets for detecting ejection or non-ejection.

  • Patent number: 8955948
    Abstract: The invention concerns a device forming a continuous inkjet printer cabinet including a combined ventilation system for the electronic compartment and consumable fluids compartment (ink and solvent). According to the invention, condensates derived from solvent vapors not condensed by the condenser are extracted through a pipe then retained in order to be evaporated by the ventilation airflow. The solution according to the invention ensures that the increase in solvent concentration around the printer remains below the legal limits for unpleasant smells for persons. One advantageous embodiment consists of using a heat exchanger on the ventilation airflow path, to condensate solvent vapor in the ink reservoir to enable gravity flow of vapors thus condensed and return them to the ink reservoir.

  • Patent number: 8764157
    Abstract: An inkjet recording device includes a recording head and a waste ink tray. The recording head is configured to eject droplets of ink. The waste ink tray is configured to receive the ink drained from the recording head. A surface of the waste ink tray, which receives the ink, is made of an antibacterial agent containing resin composition. A solubility of the antibacterial agent containing resin composition, which is measured by a predetermined measurement method, is 1.0 or higher and 3.0 or lower.

  • Publication number: 20140176643
    Abstract: The case 22 of a waste ink tank 13 has ribs 51, 52 that partition the space between a waste ink inlet 36 and an air vent 33. Air passages 65, 66 that connect the waste ink storage spaces S1, S2, S3 partitioned by the ribs are formed at the top ends of the ribs 51, 52. Waste ink permeates all of a sponge 21 through the space between the ribs 51, 52 and the bottom wall 24. Because a path for air to flow to the air vent 33 is constantly maintained inside the case 22 by the air passages 65, 66, air is discharged from the air vent 33 as waste ink is introduced to the case 22. The strength of the case can therefore be increased without interfering with introducing waste ink to the case and absorption of introduced waste ink by the sponge.

  • Patent number: 8727492
    Abstract: An image forming apparatus includes an image forming part to form an image by injecting a liquid. A waste liquid tank is detachably attached to the image forming apparatus to store a waste liquid discharged from the image forming part. The waste liquid tank has a memory element to store identification information A and waste liquid amount information B. A memory unit stores identification information C and waste liquid amount information D. A control unit determines a current amount of the waste liquid currently retained in the waste liquid tank at a predetermined timing in accordance with the identification information A and the waste liquid amount information B stored in the memory element and the identification information C and the waste liquid amount information D stored in the memory unit, and updates the current amount of the waste liquid in accordance with a subsequent operation of the image forming part.

  • Patent number: 8721041
    Abstract: An ink collecting system has been developed to direct ink purged from a printhead positioned above an ink collecting tray along a stepped flow path into the ink collecting tray. The stepped flow path enables the purged ink to flow from a faceplate on the jet stack, around a junction, onto a lower surface of the jet stack, and to a curved lower flange of a reservoir housing, which directs the ink away from the faceplate before the ink drops into the ink collecting tray for disposal or reuse.

  • Patent number: 8702198
    Abstract: A method of detecting fluid drops ejected from a fluid applicator unit having nozzles. The method includes establishing a detection zone to detect detection fluid drops transmitted therein and ejecting a set of detection fluid drops through a set of nozzles of the fluid applicator unit through the detection zone to a detection receiving member. The method also includes ejecting a set of warm-up fluid drops through an other set of nozzles to a warm-up receiving member in a manner in which the set of warm-up fluid drops bypasses the detection zone. The method also includes detecting the set of the detection fluid drops ejected into the detection zone.

  • Patent number: 8702229
    Abstract: A modular printing apparatus has a printing device with an inkjet print head and a box-shaped module that urges items toward the print head, for printing thereon. In an operating mode, the box-shaped module is inserted into the printing apparatus via a mechanical connection and can be removed from the printing apparatus in a service mode. A triggering mechanism acts on a locking mechanism with first and second force components that couple the locking mechanism and the mechanical connection element to one another in the operating mode to lock the box-shaped module in a bay of the printing apparatus at the printing apparatus. The second force component acts in an opposite direction in the service mode, to disengage the locking mechanism and the mechanical connection element to unlock and remove the box-shaped module.
