[Combinations of ROM Versions]

They should never be operated except in the following combinations. As only the following
combinations can have their operation checked, errors could well occur with other
combinations.

MAIN PRA-T230M-zzz 040
STM1 PMA-T230S1-XXzz 06
STM2 PMA-T230S2-XXzz 06
PFC IC-230PFC-zz 01
SRAM K-SRAM-T230Xzz 05

The first copy speed or the multicopying speed
using the ADF is somewhat slower than usual.
