[Dead] fs 1128 mfp no power

[luis8832]

Went to a customer site and the unit had no power. I had an 1128 in the office fully functional. Swapped the power pwb and the switch, no success. Swapped the control pwb, no success. I also checked the cord and the outlet, ok. Called tech support and the guy tells me the engine pwb, i just looked at the pwbs in the service manual and the engine is part of the control pwb(thank you tech support). Just wondering if anyone out there has gone thru this problem and how they resolved it. Any input is greatly appreciated.

We have seen this problem several times. It has always been the main board. You will get a C0180 code when you replace it, just run U004 and update firmware and everything will be fine. Hope this helps.

Re: fs 1128 mfp no power

I have run into this problem on a few control boards for the FS-1128. This control board gets 24 volts from the power source and has circuits that convert the 24 Volts into the voltages needed by the control board. There are a couple of small IC's in this circuit that go causing the type of problem that you are experiencing. Sometimes it will be no power or the machine will work for a short period of time then quit. Hope this helps.
