    LGC 355 to convert to 455.
    I gave to one person
    And turned.
    And it works.
    I found the on-board change.
    these changes
    tested another lgc bord 355IMG_0091.jpgIMG_0092.JPG

      here is another process

      1 ) Release lgc bord , R114 and R115 are blank. Here you have to add 2 resistor or sort .
      2 ) Remove sort connection from CN316(cable) and add this sort connection to CN311(cable)

          attention attention attention
          to change speed print toshiba 355 to 455
          1-Instead of jumpers ports cn316 and cn311 should change together in lgc board
          2- behind lgc bord
          must to remove resistor in R115 and 112
          and add this resistor or short circuit in R114 and R113
