Problem solving • Is there a hardcopy report from the reader sorter? In many cases, a hardcopy report is not available from the reader sorter. Obtaining a printout from a test run is possible, but many runs present little data other than the problem documents. A report listing all items, or an exception report listing only the rejects, are critical tools in determining the reason for the reject problem. • Are the reader sorter performance expectations realistic? Xerox MICR documents meet ANSI specifications for reader sorter performance. However, actual reject rates vary greatly, depending on paper types, the reader sorters used, printer maintenance, and reader sorter hardware conditions. • What is the reject rate significance? The expected reject rate for reader sorters is between 0.5 and 3 per cent. You should investigate for causes if this rate suddenly increases. Expected reject rates There is no ANSI reject rate specification. However, the expectation for high-speed reader sorters is a reject rate below 0.5 per cent for unprocessed documents in good condition. Xerox MICR documents are expected to be rejected less than 0.5 per cent on the first pass in high speed reader sorter tests. (This standard varies according to the country.) However, since financial documents are processed by reader sorters that are not directly 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 size Reducing reject rates To 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.
