Problem solvingGeneric MICR Fundamentals Guide 7-9• Is there a hardcopy report from the reader sorter?In many cases, a hardcopy report is not available from thereader sorter. Obtaining a printout from a test run is possible,but many runs present little data other than the problemdocuments. A report listing all items, or an exception reportlisting only the rejects, are critical tools in determining thereason for the reject problem.• Are the reader sorter performance expectations realistic?Xerox MICR documents meet ANSI specifications for readersorter performance. However, actual reject rates vary greatly,depending on paper types, the reader sorters used, printermaintenance, and reader sorter hardware conditions.• What is the reject rate significance?The expected reject rate for reader sorters is between 0.5and 3 per cent. You should investigate for causes if this ratesuddenly increases.Expected reject ratesThere is no ANSI reject rate specification. However, theexpectation for high-speed reader sorters is a reject rate below0.5 per cent for unprocessed documents in good condition.Xerox MICR documents are expected to be rejected less than0.5 per cent on the first pass in high speed reader sorter tests.(This standard varies according to the country.) However, sincefinancial documents are processed by reader sorters that are notdirectly under your (or Xerox’s) control, output quality may vary.Reject rates vary with:• Printing conditions• Reader sorter model• Adjustment or maintenance of the reader sorter• Check batch sizeReducing reject ratesTo keep the reject rate as low as possible, do the following:• Adjust the Xerox MICR printer to specification.• Use the current release of the E13B or CMC7 MICR font.
