摘要:
An ink jet recording apparatus includes: a timer (26) that outputs a signal upon measurement of a predetermined time that is longer than a predetermined cycle during a period for which recording heads (8, 9) are released from a cap member (uncapped period) after a print command has been outputted; and a flushing control means (27) that control to move the recording heads (8, 9) to an ink receiving means so that the recording heads jet ink droplets, in response to the signal from the timer (26), and to reset the timer (26). If the predetermined time set to the timer (26) is up during uncapped period, the flushing control means (27) flushes a maximum number of ink droplets, and upon end of a single round of printing, the flushing control means (27) flushes a number of ink droplets corresponding to a time measured by the timer (26).
摘要:
Ink is sucked in a first amount from recording heads by applying negative pressure of suction pumps to the recording heads in a state in which communication between the recording heads and the atmosphere is cut off by sealing the recording heads by means of caps. The ink in the caps is then discharged by causing negative pressure of the suction pumps to act in a state in which the caps are made to communicate with the atmosphere, and then wiping is effected by a wiping blade.

An ink jet recording device includes an external switch, a device for detecting the amount of ink left in each ink cartridge, and a device operating such that when an instruction to replace the ink cartridge is generated by the switch, or when a device detects an ink end of the cartridge, only the ink cartridge to be replaced is exposed through a window in the recording device. The ink cartridge to be replaced is specified, and only the specified ink cartridge is automatically moved to a replaceable position. Correct replacement of more than one ink cartridge is ensured, and the cartridge replacing work is simplified.

摘要:
An ink jet recording apparatus having a sheet forward roller 8 and a pump unit 11 connected to a single drive motor 7, and a drive force is transmitted to the pump unit 11 through time lag mechanisms 33-34 that cause a time lag at the time of switching rotational directions. Sheet feeding/discharging operation and ink sucking operation are performed with the single drive motor by taking advantage of a timing at which there are no load fluctuations accompanied by the switching operation, without requiring any switching mechanism.

A method is disclosed for conducting solid printing on a tape-shaped recording medium without leaving any unprinted portions on either the sides, leading or trailing ends thereof. A portion of the image-receiving surface of a tape-shaped recording medium of a pre-determined width which is narrower than the full width is used for the actual image-receiving surface, while the other continuous portions are used as dummy image-receiving surfaces. The solid printing action involves solid printing in such a manner that the printing overlaps the edge of the image-receiving surface onto the outer dummy image-receiving surfaces. After solid printing, the center image-receiving surface portion is cut loose from peeling paper, leaving the unnecessary dummy image-receiving surfaces. The image-receiving portion cut loose may be applied to a desired surface, as a piece of printed tape-shaped printing medium solidly printed without unprinted gaps at the edges.
