It is possible to differentiate the reading results of MICR, ASB, and real-time status. Refer to Appendix B for data identifying method. The identification result is not cleared until: the next FS a 0 is executed, ESC @ is executed, or the printer power is turned off. Data transmission (real-time commands and the like) should not be performed during MICR reading, because it affects the reading precision and may lower the recognition rating. When bit 4 is 0 (re-reading possible) and FS a 0, FS a 1, FS a 2, or FS b is received, the printer executes each command. When any other code (except for real-time commands) is received, the printer ejects the check paper, ends MICR function, and selects the default paper type for ESC c 0 automatically. If the printer receives FS a 1, FS a 2, or FS b when bit 5 is 0 (normal end) and bit 4 is 1 (re-reading impossible), the printer executes each command. If the printer receives any other code (except for real-time commands), the printer ejects the check, ends MICR function, and selects the default paper type for ESC c 0 automatically. Paper feeding with the paper feed button and auto loading cannot be performed during the period from starting MICR character reading to ending check paper ejection. Also, do not change the ink ribbon during this period. Header: H NUL: H Each bit of n is used as follows: Bit Off/On Hex Decimal Function 0,1 Readable fonts. See the table below. 2,3 - -- Undefined 4 Off 00 0 Rereading possible. On 10 16 Rereading not possible. 5 Off 00 0 Reading normal. On 20 32 Reading not normal. 6 On 40 64 Not used. Fixed to On. 7 Off 00 0 Not used. Fixed to Off. Readable Fonts Hex Decimal 00 0 01 1 02 2 03 3 Font E13B CMC7 Undefined Undefined Bits 0 and 1: Identified character fonts. When bit 5 is 1 (abnormal end), either bit 0 or 1 has no meaning. Bit 4: Under the following conditions, the printer sets bit 4=1 (rereading not possible) ¬When bit 5=1 (abnormal end). (except for the case that “?”s are three or less) ­If the MICR status is “ Not Selected”. ®When rereading possible number reaches the maximum (maximum is one time).
