IPC: B41J2/175
Filed: 2003-08-05
Abstract: <P>PROBLEM TO BE SOLVED: To prevent an image quality decrease due to a temperature rise of a recording head integrated with a sub ink tank.  <P>SOLUTION: In an inkjet recording device, a temperature rise degree of the recording head is detected on the basis of a previous temperature ta and a post temperature tb of the recording head, and the number of pixels. An ink residual quantity is calculated from the temperature rise degree. Ink refilling is executed when the ink residual quantity is small (steps 130-142). Also, a temperature of the recording head after printing is estimated from the number of pixels of a page to be printed next and the temperature rise degree, and ink refilling is carried out (steps 144-148 and 142). The temperature rise of the recording head is suppressed, and generation of pixel defects or the like to be caused by the temperature rise of the recording head is prevented. Thus high-quality image printing is enabled.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
