Roland SP300 temperature too low fault, component help?
Hi all
I have a roland sp300 with a mainboard fault. when turning machine on error pops up on screen temp too low. will start up in service mode but cannot print as heaters dont work in service mode.machine has had a different board in it and works fine, so we know fault is on the board.
The question is does anyone know which component i need to be checking as i am sure board could be saved.
Thanks in advance.

all sorted was a resistor on the board,managed to follow the schematic diagram on a service manual that came with the printer, traced everything back from the thermistor on the print head.
hopefully of some help to someone in the future, cost a few pounds to repair, cheaper than a new board!! and were back in business again 🙂 -
Hi Guys,
Looking for some advice!!
My Roland SP300 is playing up today, see picture below I have cleaned the encoder and the sensor but it was still doing it :bangshead:
when I now go to turn the machine on it is saying temperature to low. It still start in service mode!!
I’m a bit confused as to what it is anybody got any ideas
the printer was fine on Monday and hasn’t been used until today and it started doing this.
thanks
Graeme

Managed to clear the temp to low warning I think I knocked one of the ribbon cables

You can bypass the heating mode simply by pressing the pause button whilst it is heating and waiting to get to temperature

Yeah managed to clear it still printing as in the picture. I swapped the head cables and the black a cyan fire ok but yellow and magenta don’t fire at all also turned encoder upside down still the same

After a lot of f ing about I managed to get it going.
Still a weird one though ended up swapping the ribbon cables coming in to the print carriage from the main board ( swapped at both ends) and low and behold it started working
