Re: Ricoh MP C 4504

regarding how many volts from neutral to ground?
arent they the same..0 volts?
I MEAN THE NEUTRAL and ground both connect to the same ground bar in sub panel???

If it is indeed a sub panel, NO. From National Electrical Code 214:
At the service panel (ONLY AT THE SERVICE PANEL - HUGELY IMPORTANT) the neutral bus bar is bonded to ground. However, any sub-panel after the primary service from there MUST have an isolated neutral. DO NOT DO NOT DO NOT bond neutral to ground in a sub-panel.

If there is a load on the circuit you should see 1-2v between neutral and ground.

I have encountered electrical outlets with floating grounds, ground terminal not connected to the ground bus at the AC panel. I have actually seen a "ground" pin on an outlet that measured half way between hot and neutral.

Re: Ricoh MP C 4504

ok..I ve never had to test the voltage between neutral and ground and especially with a load on...
I guess that can left to the newbies to do when they are focused on texting with their phone at the same time as testing....
That will wake them up..
I Still remember the time i have a bad high voltage power pack and went to ck it and got hit wth 6,000 volts..
Low amperage but it left a big impression...

Ground to neutral spikes can be just as bad as hot to neutral and hot to ground

Re: Ricoh MP C 4504

Do internal test pages take just as long to print?
Does the SMC show any "hidden" codes?
Have you tried a new HDD just in case it's a really bad coincidence that the HDD died on your watch?

Re: Ricoh MP C 4504

Did you have tested that machine right before you moved it?

So, you put the power off, waited about 3 minutes untill the switch automaticaly went off.
Than you rolled (?) it away to another position in that room but with the cord in the same outlet...
(Did you bounced onto something?)
You have putted the machine back on and .... whoopie, here we are.
Is this correct?

Re: Ricoh MP C 4504

This seems like an electrical power problem, if you've checked the devices internal PSU/Controller/HDD etc then you should really get a Sparks in to check the Supply as it may not be a machine fault.

In the bible Job ask himself why does evil stroke him so much?
How is the situation now on this "church machine"?

Re: Ricoh MP C 4504

I believe you have a bad HDD. Some of the sectors on it have been damaged causing less available space resulting in longer boot times and other virturial memory issues. Still can format wont help.

Thanks for all of the replies. Some wonderful suggestions. Swapped HDD and RAM, for shits and giggles, with no change. Biggest improvement came when I updated Smart Ops panel firmware. It is installed from an sd-card thru slot on SOP. Don't know why SOP would lose or corrupt firmware, but machine is now running properly.

Re: Ricoh MP C 4504

Had a smart Op do this a while ago, Customer pulled plug without shutting copier down properly. Luckily the f/w update brought it back around.
Another time, had a customer move an MP C306, and when they moved it, they used the op panel as a pushing point, completely took out the op panel (black screen, no lights), but machine would still warm up and try to do its thing. Upon receiving a new SOP, installed it, and had the symptom of the picture of the machine on display being distorted when door was opened. F/w update solved that too.

I suspect that the plug was pulled prematurely this time also. Thanks for the response.
