Verifying Read of MICR Characters
This test reads the characters on a check and prints a hexadecimal dump of the
characters on the receipt. It is also referred to as the MICR Read and Print Loop
test. This is a continuous test.
Note: The MICR check reader feature has been factory adjusted for a
normal operating environment with a host computer. However,
additional devices, such as CRT monitors or large metal surfaces
near the printer, can affect the printer’s magnetic field, causing
intermittent reading errors when the MICR check reader is in
operation.
This condition can be easily diagnosed by checking the noise level of the MICR
check reader. See the next section, “Checking MICR Noise Level” for more
information.
Caution
The DIP switches are set at the factory to predetermined settings. Change the
settings carefully to avoid changing other functions.
1. Turn the printer off.
2. Turn the printer to the back to access the DIP switches and write down the
current switch settings.
