Retrofit Information

Due to software change for the Japanese version, the part number of the ROM on the DF
main board was changed from A4655160 to A4655180.(See MB No.18 for A465 issued
on March 31,1990.)

However, we found the following problem when P/N A4655180 is installed on the DF main
board.

When an original misfeeds, it is necessary to open and close the DF cover two times to
reset the original misfeed. (The original misfeed cannot be removed by opening and
closing the DF cover only once.)

NOTE: This problem occurs only when the P/N A4655180 is installed on the DF main

and the DF is installed on the M210.
