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
