When printing on the same printing object with multiple print nozzles in the past, consideration was not given to cases in which the time relationships of the set times and times-to-be-printed become mismatched between the respective print items of the print nozzles. To solve this problem, an inkjet printer that prints on a conveyed printing object and has multiple print nozzles, multiple auxiliary control units for controlling the printing performed by the multiple print nozzles, and a common main control unit connected to the multiple auxiliary control units via communication unit is provided. The main control unit extracts the time relationship of the set times and the time relationship of the times-to-be-printed between the items to be printed by the respective print nozzles of the multiple print nozzles and revises the print data so as to preserve the time relationship of the set times.

An inkjet recording apparatus includes an ink container. The ink container stores an ink for printing on a printing object. The inkjet recording apparatus also includes a stirring mechanism. The stirring mechanism stirs the ink stored in the ink container. The stirring mechanism includes a stationary shaft and a rotating body. The rotating body rotates around the stationary shaft. The stationary shaft and rotating body are placed in a lower part of the ink container.

A device for recovery of the atmosphere containing solvent vapors from at least one ink recovery reservoir of a print machine comprising: n (n1) filter(s) arranged at the outlet from at least one ink reservoir (10). Each filter comprises an inlet face, an outlet face, a filter body between the two faces, and conduit(s) for recovering at least part of a liquid condensed on the surface of the inlet face before this liquid has passed through it. Each filter is either: upstream from a condenser, an atmosphere output from the reservoir, passing through the inlet face, and then the filter body and the outlet face before being sent to the condenser; or downstream from the condenser, an atmosphere from the condenser passing through the inlet face, and then the filter body and the outlet face before being sent to at least one print head of the print machine, respectively.

A collection unit configured to collect ink mist generated due to a discharge of ink from a head configured to discharge the ink includes a filter for capturing the ink mist and a liquid supply portion configured to supply a liquid to the filter.

An inkjet recording apparatus includes a recording head, an ink tank, a supply flow path, a supply pump located in the supply flow path, a collection flow path, a relief flow path connecting a first position in the supply flow path to a second position in the supply flow path, wherein the first position is located at a downstream side of the supply pump in the supply flow path and the second position located at an upstream side of the supply pump in the supply flow path, and a differential pressure regulating valve located in the relief flow path and configured to, in a case where the pressure of the pumped ink in the supply flow path is larger than a predetermined value, open the relief flow path so as to allow ink in the supply flow path to flow from the first position to the second position.

A print head of a continuous ink jet printer, including, in a cover: means for producing at least one ink jet; means for separating drops of jets intended for printing from those that do not serve for printing; a slot, enabling drops intended for printing to get out; a recovery gutter (7) for drops not intended for printing, the recovery gutter comprising an ink recovery volume (12); at least one detection conductor (20), arranged inside the head; means (16) for detecting a variation in impedance of at least one of the detection conductors when ink (21) is present in contact with the conductor or with a dielectric layer (22) in contact therewith.

A drainage container configured to be attached and detached in an attachment/detachment direction to and from an apparatus including a discharge portion to discharge drainage and configured to store the drainage discharged from the discharge portion, includes: a housing that stores the drainage and includes an opening formed in an upper surface of the housing; an accepting portion that accepts the drainage discharged from the discharge portion; and a lid portion configured to open and close the opening, in which the lid portion takes on an open state to open the opening when the drainage container is attached to the apparatus, and the lid portion takes on a closed state to close the opening when the drainage container is detached from the apparatus.

A blowout port for gas is efficiently configured without impairing mist collection performance. Two blowout ports for gas are adjacent to each other by interposing a partition. An end of the partition is provided at a position near a deep side of the two blowout ports relative to ends of the two blowout ports so as to form a step.

A removable module for an inkjet printer comprises: a housing; a plurality of fluid conduits; two cartridge connections; a printer connection; and an electrical link. The plurality of fluid conduits are disposed within the housing. The two cartridge connections are each for releasable engagement with a fluid cartridge. Each cartridge connection is exposed by the housing and comprises: a fluid connector for engaging an outlet of a fluid cartridge to allow fluid to flow from the engaged cartridge to one of the plurality of fluid conduits; and an electrical contact arranged to contact a corresponding contact on the engaged fluid cartridge. The printer connection is for releasable engagement with an inkjet printer.

A device for recovery of an atmosphere containing solvent vapours from at least one ink recovery reservoir of a print machine comprising: n (n>1) filter(s) arranged downstream from the at least one ink recovery reservoir, each filter: comprising an inlet face, an outlet face and a filter body between these two faces, and each of the filter being upstream from a condenser or other solvent extraction structure, an atmosphere output from the at least one ink recovery reservoir passing through a separator and through the inlet face, and then through the filter body and through the outlet face before being sent to the solvent extraction structure, the device further comprising at least one second reservoir to recover liquid from the separator.
