Publication number: 20100085397Abstract: A printing apparatus includes a transporting unit that transports a printing medium in a transport direction. A print head group has print heads disposed at an interval in the transport direction. Each of the print heads has ink ejecting nozzles in a range substantially perpendicular to the transport direction, including a margin area outside an image forming area in the printing medium. Image detection units correspond to the print heads except for at least the uppermost upstream side print head in the transport direction. A printing control unit controls the print heads so that the print heads eject ink on the printing medium. The uppermost upstream side print head prints a reference timing pattern on the margin area. A print head corresponding to the detection unit prints a checking timing pattern when the reference timing pattern is detected, thereby controlling the ink ejection timing of the printing apparatus.Type: ApplicationFiled: October 2, 2009Publication date: April 8, 2010Applicant: Seiko Epson CorporationInventors: Ryoichi TANAKA, Teruaki KAIEDA, Hirokazu NUNOKAWA
