Publication number: 20200301326Abstract: A conveyance control device includes a fixing device including a first rotary body, a cooling device including a second rotary body, and control circuitry. The circuitry records a first drive amount for the second body when the first and second bodies are driven at a speed, a second drive amount for the second body when the second body is driven without the first body being driven, a third drive amount for the second body when the second body is driven to rotate faster than a rotating speed and the first body is driven, and a fourth drive amount for the second body when the second body is driven to rotate slower than the rotating speed and the first body is driven. The circuitry performs correction based on the drive amounts in such a manner that a drive amount of the second body becomes equivalent to the second drive amount.Type: ApplicationFiled: March 18, 2020Publication date: September 24, 2020Applicant: Ricoh Company, Ltd.Inventors: Kimiharu Yamazaki, Hideyo Makino, Susumu Mikajiri, Yoshinari Onuma, Satoshi Nakayama, Hiroki Yamamura, Kohta Aoyagi
