Diagnostics and Print Tests

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.
