Re: Ricoh C900s need help, please

Thanks Iowatech. There also is a TSB for the CNB (connector board) and random codes and errors. If this is an early production C900 this may be the problem. Still doesn't add up after the region change though!!!!!!!!!!!!! I'll look up the TSB and post it.

Thank Iowatech and Tonerbomb, I'm right here waiting for your news

Thank Tonerbomb, I have checked Relay card, it is a new type and works perfect (all relays are closed when machine starting up). Do you have any more ideas?

Re: Ricoh C900s need help, please

Now, Our technician suspects IOB PBC board does not work perfectly. He found SW101 switch array on PCB, is there any hard config by changing logic state of this switch? thanks

Re: Ricoh C900s need help, please

We also found that SELF CHECKING procedure is not running when startup, so the machine doesn't go to ready step. So, I dont know where to go now.
In case changing IOB PCB board, we dont have opportunity to have back-up here. If any favour, could we order from Ricoh?

Thanks

Re: Ricoh C900s need help, please

I don't know if I'd do anything with the switches on the IOB board. I mean, if the machine has worked properly in the past with the switches in the positions that they are in now, it is somewhat unlikely changing them will do any good.
This might be stupid, but is there an error code like SC542 or something (I think it could be anything in the range of SC540 to SC548, but there might be more) on the machine? If so, you should try to reset it before you purchase any parts for the machine. On the machines I have seen that series of error code on, sometimes you have to go into SP5 and look for "SC reset", and sometimes you have to enter "Special Service Mode", and then check SP5.
Did you find the "birth certificate"?

Re: Ricoh C900s need help, please

wait a minute here. this all went bad after you changed the region code right?? Do you have the birth certificate for the machine( orignal factory settings pages for your specific machine)???? If you do try to input these settings to get the machine back to it's factory state. you will have to do some additional adjustments when you do this also.

I wouldn't start swapping boards on a guess just yet. For 1 they are very expensive for this machine and 2 they don't fail very often. Check for the fuser codes as Iowatech said. Did you find the birth certificate??? (original data sheets).

Re: Ricoh C900s need help, please

Thank you, I'll check the fuser code as Iowatech said. We bought used machine and it have no birth certificate, let me check the seller. If you think any more ideas, please tell me.
Thank you.
