NOTE 1. To meet the safety standard, the fuse on the board has been changed (11070391 → 11070752) from the first
production machines. As a result, the part number of the ADF main control board has also been changed. (The
difference between A0285811 and A0285805 is the fuse only.)
NOTE 2. To enable the use of F4 size paper (8
1/2 x 13"), the ROM’s on the main board, operation ROM board, and paper feed
control board have been changed. (Their part numbers have not been changed. For details, refer to RTB No. 1. ) To
enable the use of the same function on the ADF (original size detection), the ROM has been changed from the March ’92
production. (5 machines of the first production use the old type ROM : A0285851.) The part number of the board is still the
same (A0285805 → A).
