FS3140MFP - 0840 Error codes on separate machines

[DWise]

We have a customer that has had two separate FS3140MFP's display the same error (0840) in this particular office.

With the first printer, they replaced the batteries twice and the Main PWB. After not being able to clear the error, they replaced the printer with another one that was working well (in another office, same building). Replacement printer shows same error. They can power-cycle the printer and the error will clear.

The tech is going to upgrade firmware and check the power (in room), but I just wanted to check and see if any one else has had a similar issue?
