The measuring devices of copier and printer supplies are checked and calibrated following the procedures given by part of manufacturers. In this report, a study to improve the efficiency of managing these measuring devices was conducted by reviewing the checking frequency and calibrating limit based on JIS Z9000 (General Rules for Measurement and Calibration). For the toner softening point measuring device, the economic benefit after optimizing the checking and calibrating method was estimated. Then measuring error of the device was analyzed. From the results of study, the total loss was greatly reduced by optimizing the checking interval and calibrating limit. The measuring error was also reduced by reviewing the control limits of measuring conditions.
