Verifying Read of MICR Characters
This test reads the characters on a check and prints a Hex dump of the characters
on the receipt. It is run during normal operation (on-line mode).
Caution: The DIP switches are set at the factory to predetermined settings and
should generally not be changed. If you must change the settings do so carefully
to avoid changing other functions.
1. Press the On Line button to take the printer off-line.
2. Set the DIP switches to the settings in the table.
Switch 1 must be set to Off. Switch 8: On = knife, Off = non-knife
Switch 1 Switch 2 Switch 3 Switch 4 Switch 5 Switch 6 Switch 7
Off On Off Off Off Off On
3. Close the front cover and press the On Line button to put the printer on-line.
4. Insert a check into the slip station.
The printer waits until a check is inserted. When a check is inserted and
detected, the platen closes and the characters are read by the MICR reader.
The decoded data is printed to the receipt, the platen is opened, and the test
is re-started.
If the MICR reader misreads the characters, question marks “?” are printed
on the receipt. If the MICR reader is unable to read any characters, “NO
MICR CHARACTERS” is printed on the receipt.
5. Press the On Line button to take the printer off-line and open the front cover.
6. Set the DIP switches back to the settings for normal operation (on-line mode).
See “Switch Settings” in the “Communication” chapter for the settings.
7. Close the front cover and press the On Line button to put the printer on-line.
