KEY check sum code
4.2. Test procedure
The keyboard is checked using the check sum code of the key code.
If the check sum code is not entered, the check is made using the
check sum code of the default keyboard arrangement.
The check sum 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.

NOTE: Calculation of key check sum data
Hard codes (hexadecimal number) at the position (excluding
feed key) where there is an input data contact are added.
However, the final key (CA/AT) is not added.
This data to which hard codes have been added is converted
into a decimal number value, which will become the check
sum data that will be entered when DIAG is started.
