A liquid discharging head includes a head chip including a plurality of energy generating elements configured to discharge liquid, and liquid chambers provided around the energy generating elements, and a common passage member configured to define a common passage communicating with all the liquid chambers. Liquid is discharged from the liquid chambers by driving the energy generating elements so as to apply a discharging force to the liquid. N-number of common passage members (N&#x2267;2) are provided, and each includes an inlet for supplying the liquid to the common passage and an outlet for ejecting the liquid from the common passage. The inlet of the first common passage member is connected to a liquid supply member. The inlet of the N-th common passage member is connected to the liquid supply member via an opening-closing valve and to the outlet of the (N&#x2212;1)-th common passage member.

Liquid discharging head, liquid discharging apparatus, and bubble removing method for the liquid discharging apparatus

A liquid discharging head includes a head chip including a plurality of energy generating elements configured to discharge liquid and liquid chambers provided around the corresponding energy generating elements, and a common passage member configured to define a common passage communicating with all the liquid chambers in the head chip. the liquid is discharged from the liquid chambers by driving the energy generating elements so as to apply a discharging force to the liquid. The common passage member includes an inlet through which the liquid is supplied to the common passage, and an outlet through which the liquid is ejected from the common passage. The common passage includes a ceiling surface having a groove extending from the inlet toward the outlet.

A head cartridge and a liquid ejection apparatus are provided in which cleaning performance of cleaning means is improved using a liquid absorbing force of a wiping member produced along with restoration of temporarily increased elastic displacement of the wiping member. An elastic displacement h (height of a projection) of a cleaning roller temporarily produced by the projection arranged at a position in the foreground of ink ejection nozzles in the cleaning direction of a nozzle surface is established to satisfy the following condition:&#x3e;()(/2&#x2212;&#x3c6;/2),where the restoring speed of the elastic deformation of the cleaning roller is denoted as Vu; the moving speed of the cleaning roller is denoted as Vr; the movement distance of the cleaning roller from a restoring initiation point of the elastic deformation to the center of the liquid ejection nozzles is L; the contact width between the cleaning roller and the nozzle surface is n; and the diameter of the ink ejection nozzle is &#x3c6;.

A connection apparatus is disclosed which includes a connection source and a connection destination. The connection source includes information about a predetermined connection destination; and a connecting element for making a connection request to the predetermined connection destination based on the information about the connection destination and, given a permission, for automatically connecting to the connection destination. The predetermined connection destination includes a receiving element for receiving the connection request from the connection source, a judging element which, upon interpreting the connection request, judges whether the connection source is a predetermined connection source or not, and a permission granting element which, if the judging element judges the connection source to be a predetermined connection source, then grants connection permission to the connection source.

A negative pressure generated inside a liquid-ejecting head can circulate liquid between the liquid-ejecting head and a liquid tank, prevent the liquid from leaking out of nozzles while the liquid is circulating, and remove bubbles contained in the liquid. A head cartridge includes a printhead ejecting ink from ink-ejecting nozzles formed in a nozzle plate of the printhead, an ink-supplying conduit supplying the ink from an ink tank to an ink chamber in the printhead, an ink-refluxing conduit refluxing the ink from the printhead to the ink tank, and a liquid-delivering pump disposed on the ink-refluxing conduit and circulating the ink between the printhead and the ink tank. The liquid-delivering pump is driven to generate a negative pressure inside the printhead to circulate the ink between the printhead and the ink tank.

Head cartridge and liquid-ejecting apparatus

A platen plate for supporting an ejection object for liquid droplets ejected from each nozzle on the bottom surface of a liquid ejection head can secure the flatness of the ejection object so as to appropriately eject ink as well as can prevent the contamination of the bottom surface of the ejection object. The platen plate is provided with a plurality of ribs raised from its bottom surface so as to extend in a conveying direction of a recording sheet and arranged at predetermined intervals in a width wise direction of the recording sheet, and out of a region where ink droplets ejected from the each nozzle are landed, the bottom surface of the recording sheet is supported with top faces of the ribs so as to define a distance between the recording sheet and the ink ejection surface, and within the region where ink droplets ejected from the each nozzle are landed, the rib top faces are formed to have a height, or the ribs themselves do not exist, so that the rib top faces are not brought into contact with the bottom surface of the recording sheet.

A printer performs a printing operation by driving a cartridge to discharge ink. The ink in the printer is billed according to the amount of actual use of ink. In a service center, the head ID is first input. Then, the head ID is verified against the user ID. The amount of the use of ink is checked. Then, the billing amount for the actual use of ink is determined. The user is requested to pay for the cost.

Accounting apparatus, accounting method, and computer-readable program storage medium for storing program having accounting function

A distribution container containing storage liquid is mounted in a cartridge holding section of a line head to substitute for an ink cartridge during transportation and storage of the line head. The storage liquid prevents air from flowing into the line head through nozzles, and thereby avoids discharging failure, for example, no discharging or insufficient discharging of ink.
