Retries will not be attempted on print errors.
Attention: Stored commands can increment status byte 6. See “Predefine
messages” on page 22.
Check processing commands - 2CR only
This printer can process the check entirely without taking it from the printer. It can
read the magnetic ink character (MICR) line, frank the back of the check, and flip
the check to print the face of the check.
Note: To print the face of the check, select the document station in landscape
mode as the print station.
MICR read
Syntax:
ESC I or X'1B;49'
Purpose:
To read account information from the magnetic ink character line on
customers’ checks.
Remarks:
v Checks should be inserted upside-down from the front and against the
right wall of the printer. The check can be, but does not have to be,
registered in the printer before this command is given. The check will be
fed forward, until the bottom sensor is uncovered, then fed back for the
MICR reader reading. After the reading is complete, the check is fed to
the first print position.
v If the printer is unable to read any character on the first try, the check
will be fed forward and back for a second try. Complete status will then
be sent to the terminal - if the character was still not read it will be
identified by a Hex 3F (ASCII "?").
Note: Checks with magnetic ink printing within 1.2 inches of the right
edge of the check will not be read correctly. This occurs when the
amount field is printed on the check.
v The MICR read command increments the line count (status byte 6).
v At the completion of this command, the MICR information will be sent
over the serial I/O following the normal status bytes.
