Publication number: 20030043221Abstract: The amount of time required to perform ink drop detections may be substantially reduced by characterizing which nozzles stand a greater likelihood of failure and by performing drop detections more frequently on those nozzles as compared to nozzles that have been identified as having less of a risk of failure. Continuous drop detection on those nozzles that have been identified as standing less of a risk of failure may be substantially omitted, without negatively impacting the quality of a printed output in a substantial manner. By selectively performing drop detections on those nozzles that stand a greater likelihood of failure, it may be possible to both reduce the amount of time required to test the nozzles as well as substantially any negative impact on print quality caused by these nozzles. The characterization of the nozzles as standing a greater likelihood of failure may be based upon the selected printmode.Type: ApplicationFiled: August 29, 2001Publication date: March 6, 2003Inventors: Ramon Vega, Marc Serra, Xavier Bruch

Publication number: 20030043255Abstract: An optical write-in head for obtaining a clear image even in printing at a relatively high recording density without generating strip-like irregularities in most cases. The optical write-in head applies light carrying image information to a photosensitive substance. The optical write-in head includes an array light source having a plurality of dot light sources, each of which selectively emits the light corresponding to the image information, and a lens array facing the array light source. The lens array has a plurality of lens elements which corresponds to the plurality of dot light sources respectively. An angular aperture &thgr; of each of the lens elements is set in a range of about 14° to 18°.Type: ApplicationFiled: September 6, 2002Publication date: March 6, 2003Inventors: Shuya Ogi, Tomitaka Takagi, Koichiro Iki, Minoru Toyama

Publication number: 20030043256Abstract: The relationship between first and second side images is evaluated to determine how the position of the paper and/or the size and arrangement of an image can be manipulated to compensate for paper shrinkage caused by fusing. Show through is reduced by performing setup to adjust a pixel clock frequency and/or a photoreceptor speed, determining a residual magnification error, determining margin shifts to compensate for the residual magnification error, and applying the margin shifts. Paper shrink effects on registration can be compensated for using determinations made during a typical printer setup. Show through errors can be reduced without using a paper conditioner to pre-shrink or re-wet the paper. In simplex and duplex printing, the show through errors worsen as the image moves away from the registration edge. Using information obtained during setup, a margin shift is determined that results in a significant reduction in the maximum show through for each image.Type: ApplicationFiled: August 27, 2001Publication date: March 6, 2003Inventors: Brian R. Conrow, David M. Kerxhalli

Publication number: 20030043262Abstract: An image acquiring unit acquires a two-dimensional image from a digital camera and a stereoscopic image from a stereo image storage, and sends those images to a pixel replacing unit. The pixel replacing unit replaces pixels, among the two-dimensional image, corresponding to an object such as a pattern depicted in the stereoscopic image, by pixels of the object. An image providing unit transmits a thus generated completed image to the user. Part of the two-dimensional image is displayed stereoscopically by a stereoscopic image.Type: ApplicationFiled: August 27, 2002Publication date: March 6, 2003Applicant: SANYO ELECTRIC CO., LTD.Inventors: Satoshi Takemoto, Takahisa Ando, Ken Mashitani, Masahiro Higashino, Goro Hamagishi
