MICR reader and check flipper test (Models TI2, TI4, TI8, TI9, TG4, TG8,
and TG9 only)
Attention: Failure to perform these steps in the sequence shown will cause the
entire electronic journal to print on the CR station. Printing the electronic journal
erases the information from flash storage.
1. Insert the check face down with the magnetic ink characters to the right.
2. Press and hold both buttons to enter offline mode. When the printer ready
indicator begins blinking, release both buttons.
3. Press and release both buttons again.
4. The printer will then perform a self-test of the MICR/flipper function.
5. Remove the check.
Characters that match the magnetic ink characters are printed on the customer
receipt and the check is flipped over. Characters that can not be read will be
replaced with question marks and will be printed at the customer receipt station. If
the characters are not read properly or the check does not flip, go to “Problem
determination” on page 67.
If the Model TI2, TI4, TI8, TI9, TG4, TG8, or TG9 detects noise, it prints a message
on the customer receipt below the magnetic characters from the check (Figure 37
and Figure 39 on page 66 are examples; actual numbers may vary). The message
shows noise characteristics. You can use the noise level to position your printer to
minimize outside interference with the MICR reader. An acceptable noise level is
less than 5 percent, if possible.
Sources of electromagnetic noise (for example, displays, security towers, and other
sources) can interfere with the MICR reader read head. If the printer shows an
external noise source, rearrange the printer to make the noise source as far away
as possible from the right side of the printer. This may eliminate the external noise.
