Ricoh C7100 Power disconnected problem

[Chrb]

Dear ,
I'm new member in this forum but it is very powerful forum especially who needs help.
I have a Ricoh C7100x and I'm having a problem with ( The power cord has been disconnected) error , I changed the cables and changed the power socket and check the breaker and changed the lan cable between the fiery and the machine with no success.
so if any one has any idea how to solve this please help,
thanks

Was that message on the main frame dispolay or on the Fery?

yes it was working perfect, I turn it OFF and the next day gives me this on the main machine display screen not the Fiery

First thing I would check is to be sure the machine is plugged into a 20 Amp outlet. Also make sure there's nothing else on the same circuit. I had a 65 PPM copier that would give power error codes randomly, we discovered someone had a paper shredder on the same circuit, and every time it ran it would drop the power to the copier.

It's worth a look.

By breaker do you mean the one on the C7100 or the main electrical panel?

[Chrb]

The breaker over the two power cables on the machine , on the service manual they mentioned to check it , it works perfectly.
and regarding the power circuit, I disconnect the tray unit and the finisher , nothing connected to the machine and its plugged into the wall directly.
I really appreciate your help guys.

Most Production models are 240Volt machines. The power connection is Line 1, Line 2 and Neutral and use 2 breakers on the main panel, as opposed to non Production that are Line, Neutral and ground using only 1 breaker. Line 2 is used to provide sufficient current for the fusing unit. Since the display panel on the C7100 has power then Line 1 voltage and the error can only be with Line 2. Have an electrician check the panel.

There are two 208v cords going to the machine. Is it possible you've lost voltage to one of them?

Update.
I opened the machine and clean all the connections with electronic cleaner , every single connect, now the error for the power is gone but I have a SC442-03 which is the the 5th ITB motor ,my machine is 5 colors .
I changed the front sensor and changed the back motor still the same error .
is there any way that i can eliminate the 5th color because I have an other machine but 4 colors there is no motor at the back.
