Publication number: 20060071411Abstract: An adsorption standby unit is provided upstream in the sheet conveying direction of a sheet stacking portion, which stacks sheets to be processed thereon. During processing of sheets on the sheet stacking portion, the next sheet to be processed is adsorbed and put in a standby state by the adsorption standby unit, so that the sheet can be retained and put in a standby state without switching the sheet back.Type: ApplicationFiled: September 13, 2005Publication date: April 6, 2006Applicant: Canon Kabushiki KaishaInventors: Yusuke Obuchi, Daisaku Kamiya, Junichi Moteki, Tadashi Iwakawa, Kenji Suzuki, Masaki Seto

Publication number: 20050238399Abstract: An image forming apparatus comprises a fixing unit for fixing toner image onto a sheet on which the toner image is formed, and a redelivery path for delivering the fixed sheet ejected from the fixing unit to the image forming unit again. A curved path receives the fixed sheet ejected from the fixing unit, reverses the sheet, and delivers the sheet to the redelivery path again. The redelivery path includes a horizontal-registration detection sensor for detecting the edge of the sheet in the width direction and a color density sensor for detecting the color density and color of an image formed on the sheet. A curl-corrector is disposed downstream of the curved path to straighten the curled sheet and then send the sheet to the horizontal-registration detection sensor and the density sensor.Type: ApplicationFiled: April 11, 2005Publication date: October 27, 2005Applicant: Canon Kabushiki KaishaInventor: Junichi Moteki
