  • Patent number: 7887158
    Abstract: A droplet ejecting device has a droplet ejecting head, a rotating member, a recovery unit, and a negative pressure generating unit. The rotating member is disposed so as to oppose a nozzle surface of the droplet ejecting head, and is a conveying body that conveys a recording medium. The recovery unit has a suction hole provided at a region of the rotating member on which the recording medium is not loaded, and recovers, from the suction hole, liquid that becomes a mist at a time when the droplets are ejected from the nozzles. The negative pressure generating unit generates negative pressure at the recovery unit.

  • Patent number: 7883177
    Abstract: Tray inserts are disclosed for production printing systems. The tray inserts rest in ink trays and hold ink absorbing elements. The tray inserts and ink absorbing elements collect ink when printheads print outside of the margin of a printable medium, or otherwise discharge ink that does not contact the medium, such as during a cleaning cycle. When the ink absorbing elements become saturated and excess ink collects in the tray inserts, the tray inserts may be lifted vertically out of the ink trays and the ink absorbing elements may be removed from the tray inserts. The excess ink may then be dumped or otherwise cleaned from the tray inserts. In one embodiment, the tray inserts include drains which are used to empty the excess ink.

  • Patent number: 7878619
    Abstract: A maintenance method of a fluid ejecting apparatus having a fluid ejection head. A cap member faces an ejection region of the ejection head and a portion thereof facing the ejection region covers a space that includes the ejection surface. When the space covered by the cap member is to be uncovered, the facing portion of the cap member is tilted with respect to the ejection head. Fluid is then ejected from a first portion of the ejection region toward a predetermined region of the facing portion. The ejection head is then moved, and a second portion of the ejection region behind the first portion is positioned so as to overlap the predetermined region in a plan view. Fluid is then ejected from the second portion toward the predetermined region, and the potential difference resulting from the ejection of the fluid from the ejection head is detected.

  • Patent number: 7871146
    Abstract: The cleaning process best suited to the condition of an inkjet printer is selected and run, thereby removing nozzle clogging without wastefully consuming ink. The first time a cleaning switch 7 is operated a CL1 cleaning process is run. If the cleaning switch 7 is pressed a second time and the print pass count is less than e.g., 400, a CL2 cleaning process that uses more ink than the CL1 process is used to clean the recording head, but if the print pass count is 400 or more, the CL1 cleaning process is used. If the print pass count is less than 400 the third time the switch is operated, the CL2 cleaning process is used, but the CL1 cleaning process is used if the print pass count is 400 or more. If the cleaning switch 7 is operated four or more times and the print pass count is less than 400, a YCL cleaning process that consumes substantially no ink is used to clean the recording head, but if the print pass count is 400 or more, the CL1 cleaning process is used.
