E733 irac 7260

[roho]

Having a issue with this one, Irac 7260, E733 error shows, immediately upon boot, and then seconds later device will shut itself down. No work has been done on this device, installed a few months ago, so it seems as though this was built into this one. A previous tech had replaced dc power supplies to no avail. Wondering if anyone has had this issue before with this model, I'm wondering if there isn't a pinched wire or tight tie wrap on the fuser harness at the back, as the only times I can remember a device shutting itself off was when there was a short in the fuser area. Any suggestions or feedback would be appreciated, TIA

Looked over the drawer cable and replaced for good measure. No difference. I've went looking at all the voltage out puts, connector 1804 has no 24 volts present, and no remote signal on the relay pcb. Swapped the two dc power supplies, no change, swapped the ac inputs, no change, same connector has the issue, at that time the office closed. I'm going to go over the all night power supply next, try to trace where the remote signal is lost. Thanks for the reply!

Change the main control pcb it happend with me in ira6075

Turned out the dc controller was a red herring, swapped back the original and the remote signal and voltages re-appeared. Tried the riser pcb after getting back on path, and that was the cause of the error. Thanks for the help!
