The board of directors of Scan-Tron, a Tustin-based manufacturer of optical reading equipment, has approved the repurchase of up to 200,000 of the company’s 4.2 million shares of common stock outstanding. A company official said the action was taken in response to last month’s stock market collapse. At least 17 Orange County firms have joined hundreds of companies nationwide in authorizing share repurchase programs designed to take advantage of low stock prices.
