I don't think it is too important if you print successfully from your calculators. The only reference I've found on the internet is in this article from a Japanese site about the HP 82240B:

Quote:If you turn on the power while pressing the paper feed button, the self-diagnosis function will be activated. In the self-diagnosis function, the remaining battery level is printed from 0 to 5 at the end. I've seen INT BAD printed after F, but I'm not sure what's wrong (it was fixed after turning the power off and on several times).

Note that on the 82240B there is a factory code letter printed at the end of the character set, here it's F, which is not present on the 82240A.
