Publication number: 20140092164Abstract: A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.Type: ApplicationFiled: December 5, 2013Publication date: April 3, 2014Applicant: CANON KABUSHIKI KAISHAInventors: Takeshi Murase, Masao Kato, Shigeyasu Nagoshi, Minako Kato, Minoru Teshigawara, Yoshiaki Murayama, Susumu Hirosawa, Yutaka Kano, Satoshi Azuma, Kentarou Muro

Publication number: 20130335471Abstract: One aspect of this invention is directed to suitable drive control in accordance with an output from the temperature sensor of a printhead. More specifically, a printing apparatus by using a printhead that includes heaters and a temperature sensor on a substrate and discharges ink by driving the heaters executes the following steps. First, when printing a test pattern by using a predetermined driving pulse in a maintenance mode, a detected temperature is stored as a reference temperature in a memory. Then, in a normal printing mode, the difference between a detected temperature and the stored reference temperature is calculated, and a driving pulse for driving the printhead is selected from a plurality of driving pulses based on the difference. The printhead is controlled to be driven using the selected driving pulse and print.Type: ApplicationFiled: June 7, 2013Publication date: December 19, 2013Inventors: Takeshi Murase, Atsushi Sakamoto, Minoru Teshigawara, Kei Kosaka
