Ricoh C900s need help, please

[ducphuonghtp]

Hi guys,I have a trouble, our machine run normal until I switch SP5807 from N/A to EU, so error "fusing unit is not set correctly" appear, when I switch SP5807 back to N/A the error disappear but fusing lamps is off, so my machine is not warming up. Please help me.Thank in advance.

Re: Ricoh C900s need help, please

Why would you change the regions of the device in the first place?

The question you need to answer is what region is your device from North America or Europe, that will tell us if it is a 220v or 110v

My opinion is you have a 220v fuser in a 110v machine or vise versa.

Also if that is the case the lamps are completely different depending region, also the fuser plug wiring is also completely different hence that is most likely your issue

Thank for your answer, I changed the regions because I think I it involve in size paper, then I get it's wrong decide .
Our machine from North America, the machine is still detected fusing unit but dont supply electric for it. Whether I set Sp code?

Sorry for my poor English.

Thank you very much.

Changing the region because of paper sizes??????? Just messing around in the Service Mode is not a good idea when your not a trained tech!

Vietnam is using 220V, but sometimes also 110V, so you need to check what voltage your area is using and check what kind of Fusing Unit is in the machine.

And if the Fusing Unit doesn't warm up you'll get some kind of Service Call.

Thank you,

My voltage is 220V. How can I check the kind of Fusing Unit?

Before I had changed area the machine is normal.
Now AC drive board has no signal from IOB2, so Fusing Unit can't warm upm

Re: Ricoh C900s need help, please

If you're having 220V connected to a 110V machine from the US, that's asking for trouble. Like Imprestik says, the lamps and the wiring are different. I would also say that there's a 220V Fusing Unit in a 110V machine. I don't know what happens with this machine when you connect it to 220V, but most muchines can't handle that and the Power Supply will blow up.

My Fusing Unit is a 220V Fusing. currently, my technician test for signals in AC power board. All electronic components are good, but, no controlled signal to the board. I am sure our technician is good background in electronic engineering.

Because he doesnt have detail electronic schematics of boards, only block and wiring diagram so it is hard to distinguish errors from hardware or command from the microprocessor in PCB boards.

could you provide me higher level of electronic schematics? Other wise we can purchase for them.

THanks and brgs

Maybe you can use Special SP Mode (Press # when you press Copy SP) to revert it back to normal.

I did press following your guide. but when turn on machine, error code sc990.

I think i should re-compile firmware or back-up firmware. please advise me more. in event back-up firmware, what we have to prepare? or to do?

My machine serial number: M8795200009
thanks

Re: Ricoh C900s need help, please

I have checked fusing unit (output check), every thing is normal: motor, sensor, lamps but the machine doesn't warm-up. Please tell me if I set have to set SP code for the machine warming-up.

Thank you.

You could have damaged the nvram with your experiment. I really don't recommend you try anymore experiments on this machine. The c900 is a 220vac machine that requires 30 amp 220 service, and depending on the accessories 110vac also. You need a trained Ricoh tech for the c900. I am a trained tech, but Hanoi is out of my teritory. You can get the manuals and documentation from paul.

I was also thinking of a new NVRAM. Last thing to do might be to backup all settings, do a memory all clear, and reload all settings, but this is a very drastic solution.

In my country no one is specialist but everyone can be, just kidding but there is no a trained Ricoh technician in our country so I did it myself. How do I know the NVRAM has been damaged, please tell me the way to test NVRAM. (I think NVRAM is good because if it is defective the error code will appear. whether do I have reset some SP code or not? If you have any advice please tell.)

Thank all,

Re: Ricoh C900s need help, please

I'd like to take a somewhat different approach. Are all the cover safety interlock switches working? If the fuser isn't working and there isn't an error code, that's what I'd check first.

Thank Iowatech,
I have checked Memory Clear (5801) -006: Copier application: Execute -009: Scanner application: Execute but - 008: Priter Application: Invalid Operation. I think that's why the printer does not work. Do you think so?
