The other six are T Takano, Manoj Kumar, Arvind Singhal, Anil Saini, Bibek Chowdhury and Amalendu Mukherjee.
Takano and Kumar both held in the past position of managing director and chief executive of Ricoh India.
In an interim order, Sebi said the seven individuals "are restrained from accessing the securities market or buying, selling or otherwise dealing in the securities market in any manner whatsoever, either directly or indirectly".
Sebi has also directed Ricoh, its directors and the seven individuals to extend "all necessary cooperation to the independent audit firm so appointed" and also to furnish all information or documents sought from them from time to time.

The independent audit firm has to submit a report to the Securities and Exchange Board of India (Sebi) within three months from the date of its appointment.
In its order, Sebi said that Ricoh's financial health has been deteriorating and even after the infusion of funds by its promoters, the company has neither been able to become profitable, nor is able to meet its financial liabilities.
It also said that there is an urgent need for Sebi to intervene and take steps for determining the full extent of fraud by conducting a detailed forensic audit of the company, covering the years when the fraud is suspected to have started and if required, even beyond that, to protect the interest of the public shareholders.
