Abstract
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".

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
62 words
A method of correcting MICR data encoded on a document with magnetic ink having a predetermined intensity, comprising the steps of: (a) placing a correction sticker on the document over the MICR data to be corrected; and (b) purposely printing the correct MICR data on the correction sticker with magnetic ink having an intensity which is substantially greater than said predetermined intensity.
Claim 2
Independent Claim
62 words
A method of correcting MICR data encoded on a document with magnetic ink having a predetermined intensity, comprising the steps of: (a) placing a correction sticker on the document over the MICR data to be corrected; and (b) purposely printing the correct MICR data on the correction sticker with magnetic ink having an intensity which is substantially greater than said predetermined intensity.
Claim 3
Dependent Claim
27 words

Claim 7
Independent Claim
121 words

Claim 11
Independent Claim
98 words
A method of printing MICR characters on a correction sticker which covers MICR characters to be corrected on a document comprising the steps: (a) moving the document with the correction sticker thereon in a feeding direction to a print station; (b) positioning the document at the print station so that the leading edge of the document is positioned upstream by a predetermined amount, relative to the feeding direction, from the position that the document occupied when the characters under the correction sticker were printed; and (c) printing the desired MICR characters at least twice on the correction sticker.
Claim 12
Independent Claim
98 words
A method of printing MICR characters on a correction sticker which covers MICR characters to be corrected on a document comprising the steps: (a) moving the document with the correction sticker thereon in a feeding direction to a print station; (b) positioning the document at the print station so that the leading edge of the document is positioned upstream by a predetermined amount, relative to the feeding direction, from the position that the document occupied when the characters under the correction sticker were printed; and (c) printing the desired MICR characters at least twice on the correction sticker.
