The keyboard is checked using the sum check code of the key code.
If the sum check code is not entered, the check is made using the

The sum check data for each model is entered to the front 4 digits of
the DIAG code, and that data is compared with the key data added
until the final key (CA/AT) is pressed.
Both data are the same, the test ends, printing the number given
below.
If both data are different, the printer prints the error message.

Hard codes (hexadecimal number) at the position (excluding

This data to which hard codes have been added is converted into
a decimal number value, which will become the sum check data
that will be entered when DIAG is started.
