Ricoh MP C2500 Bridge Unit not working

[taltmeyer]

Hi,

I have 2 machines, one of them recently aquired for parts wich the older machine is lacking.
The aquired machine has an defective polygon motor and stemming from that a defective R157
SMD resisistor (0 Ohm) on the BICU on the 24V line going out to the polygon motor and the display
background illumination.

On that machine is an installed and working bridge unit and an 1000 page finisher.
The older machine has no bridge unit and no finisher installed.

Now the problem:

When installing that working bridge unit (and the finisher) to the older machine, the motor of
the bridge unit won't start (SP-5-804-153/155 output check). The junction gate solenoid (SP-5-804-158) works.

On the recently aquired machine the bridge unit works every output test without any problems.

The next thing i did was swapping the IOB (controls the bridge unit) between the two machines,
but without success.

May it be necessary to "activate" the bridge option on the older machine (i didn't find anything in
the service manual)?

Or maybe this is a connector problem on the female bridge unit connector of the older machine,
or a wire between the IOB and that connector maybe "nibbed"?

Has someone had such a problem ?


Kind regards, Thomas Altmeyer

No activating required as far as I remember it was just plug and play so think you should check connecter and connecting wires first

i would sway connectors on working machine to non working unit,'maybe a pin is bent or pushed in...
the microswitches go on these bridge unit but you would get door open on display

What's the older machine may not be compatible

What's the older machine may not be compatible

Good question. We have been assuming it is a C2500, and it may not be. The C2500 requires the BU 3000 bridge. Also would be a good idea to update the firmware to the latest and greatest which will probably still be old due to the age of the machine. I suppose old finisher firmware could cause this problem.

Hi,

first i have to thank you for your suggestions.

I've found the problem:

Both machines are MP C2500's and they are not far from another (serial numbers like),
so it was no compatibility problem...
After i did fold out the controller/BICU frame, the solution was really obvious....
It was a factory assembly error, the lower of the two connectors going to the female bridge
connector was partly out of the other connectors housing.

No complete connection to the motor side of the bridge's controller board!

Kind regards,

PS: Can someone possibly send me the latest available firmware files for these machines please?

Sorry, i didn't think about it.

Isn't it legal, since i'm owning these two machines, to get a software update from a Ricoh partner?
