How to use the MICR Reader
1. Send the command “FS a 0 n” from the host computer. Then the printer shifts to the MICR Mode and waits for the Check
Sheet to be inserted. LED3 blinks slowly in orange (repeats 1 sec ON, 1 sec OFF).
2. Insert the Check Sheet with its magnetic ink print surface up and the magnetic ink print area to the right side of the
direction of insertion, butting it against the right side of the printer. The printer feeds the Check Sheet and reads at the same
time.
3. To print on the Check Sheet, send the command “FS a 1” which feeds the Check Sheet to the print start position, then send
the print command.
4. To eject the Check Sheet, send the command “FS a 2.”
5. To have the Check Sheet read results sent again, send the command “FS b.”
