"Risograph GR3750 marks to fault T11. I need consultation to solve this problem. Or it is necessary to call to technical support?"
Error T11 means: Call service.
Here some details of the error which may help to solve it: Pressure Control Motor Lock • In 100ms from turning ON of the pressure control motor, the encoder sensor cannot detect a pulse. • In 5 seconds from turning ON of the pressure control motor, the pressure centering sensor is not turned ON/OFF. • When the fuse of the main power board is gone.

I need to repair my riso RN 2100 ep.

If its CR or TR, E-01 is main motor lock. turn off machine and hold reset button in while you turn the machine on again. Make sure your master removal unit and master feed unit are closed corectly.
