摘要:
A residual ink detection mechanism for detecting the amount of residual ink within an ink container of an ink jet printer is disclosed wherein the ink container comprises a flexible bag, and electrodes are provided at least at opposite positions of this bag to constitute a capacitor, so that the amount of residual ink within the ink container may be detected by detecting the electrostatic capacity between these paired electrodes.
摘要:
There is an ink jet printer in which an electrostriction element is associated with at least a part of an ink chamber for causing ink emission from an ink nozzle connected to said ink chamber in response to a voltage applied to the electrostriction element. Said voltage is changed in response to the ambient temperature and made higher or lower respectively in a low or high temperature.
摘要:
A recording apparatus is disclosed which is improved in operability by linking a printing head protection device with a switch mechanism. The printing head comprises an ink jet head and the switch mechanism comprises a power source switch, print switch etc.
摘要:
A recording apparatus having a black ink recording head for discharging black ink onto a recording material and at least one single color non-black recording head for discharging non-black ink onto the recording material includes a recording head driver for driving the recording heads to discharge the ink onto the recording material; and a controller for controlling the recording head driver so that a volume, per unit area of the recording material, of the black ink discharged from the blue ink recording head and deposited on the recording region of the recording material is larger than that of the non-black ink discharged from the non-black ink recording head and deposited on the recording region of the recording material.
摘要:
An ink jet recording apparatus comprising, timer means for measring an elapse time from a predetermined measurement start timing, a backup power source for supplying power to said timer means when a main power source is turned off, and control means for changing a content and/or the number of times of a recover operation for recovering and preventing a discharge error in a discharge port for discharging an ink on the basis of the elapse time.
摘要:
An ink jet recording apparatus, for recording information on a recording medium, comprises a recording head having an ink ejection outlet for ejecting ink and an ejection recovery unit for ensuring satisfactory ejection from the ink ejection outlet. The ejection recovery unit has a housing, a cap disposed on one side of the housing for capping the ink ejection outlet, and a pump disposed on the other side of the housing and linked to the cap through a tube for sucking ink. In relation to the position of the ejection recovery unit, the tube is disposed so that it has a part bending upward in a vertical direction, and the pump is disposed so that an ink outlet thereof opens downward in a vertical direction.
摘要:
An ink jet recording apparatus comprises a recording head adapted for ejecting at least two colors of ink, a discriminater for discriminating between character data and bit map data, and a controller for selecting a character data recording mode or a bit map data recording mode in accordance with a discrimination result by the discriminater. The controller controls an amount of ink ejection in the bit map data recording mode to be less than that in the character data recording mode.
摘要:
An ink jet recording apparatus and an ink cartridge for use in this apparatus are disclosed. The recording apparatus has a transport unit for transporting the recording medium, a recording unit having a carriage portion on which a recording head capable of discharging an ink supplied from an ink containing portion to effect recording is mounted, and a recovery unit capable of restoring the function of discharging the ink through the discharge port. The transport unit, the recording unit and the recovery unit are independently separable from each other. Ink passages for communication between the ink containing portion and the recording head can be disconnected while being shut off in each unit. The ink cartridge has a casing, a plurality of ink containers disposed in the casing, and positioning members formed on the ink containers. The ink containers are positioned by engaging the positioning members with each other.
摘要:
In a discharge recovery method for an ink jet recording head, a recording head having discharge openings for discharging ink therethrough, liquid paths in which recording energy generating members generating energy for discharging the ink through the discharge openings are provided and which communicate with the discharge openings, and a liquid chamber communicating with the liquid paths for supplying the ink to the liquid paths is used to drive heat energy generating means provided in the liquid chamber for generating heat energy for causing a change in the state of the ink in the liquid chamber and creating a bubble, during nonrecording, thereby causing the ink to be discharged through the discharge openings.
摘要:
An ink jet printer comprises liquid discharge recording unit for discharging ink onto the recording surface of a recording medium and effecting recording, a transportation device removably carrying the liquid discharge recording unit and movable in a predetermined direction relative to said recording surface, an ink container mounted on said transportation device and containing therein the ink to be supplied to the liquid discharge recording unit, and communication parts provided in the transportation parts for communicating the ink container with the liquid discharge recording unit and having a pipe member.
