Abstract
A method and apparatus for minimizing rejections when using correction stickers on documents which are to be read by a single channel or 'deep' MICR read head in subsequent reading operations. The method entails printing the correct MICR data on the correction sticker (which is placed over the incorrect MICR data) so that the correct MICR data is purposely off registration with the incorrect MICR data underneath the correction sticker so that the correct MICR data on the correction sticker will be encountered by a read head before the incorrect MICR data underneath the correction sticker is encountered. A double printing of the correct MICR data on the correction sticker also causes dynamic thresholding circuits associated with common MICR readers to 'key in' on the high signal level on the MICR ink on the correction sticker and thereby render the incorrect MICR data signal underneath the correction sticker to the level of 'noise'.
