FS a 1
Load check paper to print starting position
Hexadecimal code: 1C 61 31
If the parameter CHEQUE PRINT: FRONT is selected via setup, the commands loads check paper to
the print starting position.
Notes: - Since 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.
- This command is ignored unless MICR function is selected.
- After loading check paper to the print starting position, the printer cancels the MICR
function and selects slip paper automatically.
References: FS a 0.
If the parameter CHEQUE PRINT: REAR (the default setting) is selected via setup, the commands
expels check paper from the printer and sets the conditions to operate a manual front feeding. That's to
load check paper to the print starting position on the rear (i. e. to validate check paper).
See also the section Notes and Meaning of the Parameters on chapter 3.
FS a 2
Eject check paper
Hexadecimal code: 1C 61 32
Ejects check paper.
Notes: - Since this command is executed after being buffered in the receive buffer. Therefore,
there may be a time lag between command reception and starting paper ejection.
- This command is ignored unless MICR function is selected.
- After ejecting check paper, the printer cancels the MICR function and selects the default
paper for ESC c 0 automatically.
References: ESC c 0, FS a 0.
FS b
Request retransmission of check paper reading result
Hexadecimal code: 1C 62
Retransmits the previous check paper (MICR character) reading results.
Notes: - This command is executed after being buffered in the receive buffer. Therefore, there
may be a time lag between sending this command and starting MICR reading.
- When the previous MICR reading results are correct, the printer transmits header +
reading status + identified character stings + NULL to the host computer. If it is abnormal,
or when FS a 0 is not executed, the printer transmits header + reading status + NULL to
the host.
- When DTR/DSR control is selected, the printer transmits data consecutively after
confirming whether the host computer is ready to receive data. When the host is not ready
to receive data, the printer waits until the host is ready.
