Notes: -
The command is available only when input at the beginning of a line.
-
This command is executed after being buffered in the receive buffer. Therefore, there
may be a time lag between receiving the command and starting MICR reading.
-
When an undefined font is selected, this command is ignored.
-
If the MICR function is not selected when this command is executed, the MICR function
is selected and the printer enters the personal check waiting status. When slip paper is
selected for printing, the printer ejects the current slip, and then waits for check paper to
be loaded.
-
When this command is executed with the MICR function selected and re-reading
possible, the printer re-reads check paper.
-
The personal check wait time is t1 x 1 minutes depending on the ESC f t1 t2 setting), and
the printer starts reading t2 x 0.1 seconds after detecting insertion of a personal check.
-
The printer processes only the real-time commands during the paper wait time.
-
The check waiting status continues until: a check is inserted, the waiting state is
canceled, the waiting time t1 set by ESC f elapses, or the power is turned off. When
check waiting state is canceled, or when the wait time elapses, the printer ends reading
abnormally. The printer starts reading when a personal check is inserted.
-
When characters are not detected or when an error occurs, the printer ends reading
abnormally. Otherwise, the printer ends reading normally.
-
When the printer ends reading abnormally, the printer ejects paper, selects the default
paper type for ESC c 0, and ends MICR function. When a recoverable error occurs, the
printer selects the default paper type for ESC c 0 automatically and ends MICR function
when recovering from the error.
-
If the characters read are not identified as the specific character font, the printer converts
the data to "?".
-
After ending MICR reading normally, the printer transmits header + reading status +
identified character stings + NULL to the host computer. In other cases, the printer
transmits header + reading status + NULL to the host computer.
-
If an error occurs before transmitting the identification result, the printer does not transmit
the identified result.
