BENCHMARK LOCATION INDICATOR Abstract of the Invention A method of initializing an optical scanning system by centering a benchmark code in an electrically adjustable benchmark window, the benchmark code being scanned by the optical scanning system while being transported through a paper handling machine. The improvement comprises the steps of providing an encoder for timing the machine cycles of the paper handling machine as a plurality of documents are processed therethrough; conveying a document containing a benchmark code to be scanned past a scanning device of the optical scanning system; enabling a counter at the lead edge of the electrically adjustable benchmark window: incrementing the counter once for every two encoder pulses; disabling the counter when the scanning device detects the benchmark code: displaying the count of the counter in a LED display; and adjusting the location of the benchmark window so that the benchmark code is substantially centered in the benchmark window based on the count displayed on the LED display.
