MICR commands
MICR reading
These commands control the Magnetic Ink Character Recognition (MICR) check reader, including how it parses the
character strings on checks.
The section, MICR parsing, describes how to create a parsing format and how to create and maintain an exceptions
table.
Read MICR data and transmit
ASCII
ESC w 1
Hexadecimal 1B 77 01 A776: 1B 77 01 = read & transmit MICR, position for endorsement
1B 77 02 (B780 only) B780: 1B 77 01 = wait for check, read & transmit MICR, eject check
B780: 1B 77 02 = wait for check, read & transmit MICR, position for endorsement
Decimal
27 119 1
Default: All data returned
Reads and transmits the MICR data and adds a carriage return (0x0D). One status byte precedes the MICR characters.
If no parsing format is selected with either of the define parsing format commands (see below), all data will be
returned, which is the default.
Status Status byte value
Good read, data follows 0x00
Bad read, data follows 0x01
No check present, no data 0x02
Paper jam, no data 0x03
No MICR characters, no data 0x04
MICR characters ASCII Hexadecimal
Numerics 0 ... 9 0x30 ... 0x39
Unrecognized character ? 0x3F
Space 0x20
Amount symbol & 0x26
Dash symbol ‘ 0x27
“on us” symbol ( 0x28
Transit symbol ) 0x29

Resends the previously decoded MICR data (as if the parsing has not been defined) to the host. The return
data is defined in the “Read MICR data and transmit” command (1B 77 01) without parsing and presents the data from
the last MICR read since power-up or reset or indicates in the status that no read has yet occurred.
