MPc6000 SC536, 537 and 538

[Llama God]

I'm back, bitches!

Anyway, I'm having an ongoing problem with an MPc6000 which, when it's powered on, comes ready then shows an SC536 (yellow dev fan) error. However, in the SC history it's logging SC536, 537 and 538 each time, one for each of the colour fans.

I've changed the CNB board, updated the firmware and changed the harness, all to no avail. I'm now escalating it to Ricoh so that they can come out to sort it. Well, hopefully anyway.

Has anybody else had this issue?

Thanks in advance,

Chris

Check them how? It's not possible to see, hear or feel any of them running in SP5804 as the hopper unit has to be installed to run them. Also, the codes relate to the dev fans.
