Formulas

The waiting time is t × 100 ms for every macro execution.

m specifies macro executing mode when the LSB (least significant bit) m = 0

The macro executes r times continuously at the interval specified by t when the LSB (least significant bit) of m = 1.

Exceptions

If this command is received while a macro is being defined, the macro definition is aborted and the definition is cleared.

If the macro is not defined or if r is 0, nothing is executed.

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
Decimal			B780:	1B 77 02	= wait for check, read & transmit MICR, position for endorsement
	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
