[Misc] MP C4502 indicating finisher cover open and acting strange

[Martie]

Hi fellow technicians!

I have encountered a problem that I cannot solve, perhaps you can give me some ideas of what might be causing this.
It's a Ricoh MP C4502, with a SR3110 finisher, that keeps indicating that the finisher cover is open even though it's not. And while it keeps doing this one of the arms in the jogger keeps going back and forth. This only stops when I actually open the finisher cover. To make it easier to understand I recorded what happens from when I start the machine until it is up and running, have a look:

The machine gets very unresponsive, it takes a couple of minutes sometimes to go through menu uptions, for instance like pressing the info button in the video.

The history of this machine is that about a week before this problem occured one of my colleagues was on this machine for another reason and he ended up with updating the firmware. For some reason the machine stalled when updating the fax module. Nothing happened for 20-30 minutes so he switched the machine off and started it up again and the machine worked just fine. One week later this happened.

So far I have replaced the following parts in the finisher: cover switch and its harness. Both PCBs and the harness between the finisher and the copier machine. Nothing helped. I have replaced the IOB board in the copier and the bridge unit without any success. Also, all the firmware is updated to the latest versions.

Thank you!

Your English is perfect, don't ever apologise for it.

I know you've said the firmware is up to date, but is the finisher firmware the correct one for the SR3110?

That's a good question and to be honest I have not really checked it in detail. I have assumed that it is the correct firmware since I've downloaded it from our national Ricoh FTP server that contains all latest firmware for each machine model and it's accessories. Since I haven't been able to reach SP mode or system settings when the finisher is connected I cannot see the firmware version on the finisher. It only works when the finisher is disconnected but that means it doesn't show what firmware version the finisher has. I just checked the firmware version available on My Ricoh and it is the same that we have used.

Also, I forgot to mention that the machine does not throw any SC codes, only 792 since we leave it running with the finisher disconnected.

It's a one hour drive (one way) to this machine and the customer does not have an other 4502/5502 that I can test the finisher on and unfortunately we don't have a matching machine back at the office either so it's really frustrating.

Has the firmware been reloaded again since the other tech had updated it? If not, do so using a different SD card and a fresh download of the firmware. I would actually load the peripheral firmware separately from the mainframe firmware. Also, is JAVA up to date? Since the first firmware update stalled loading the fax firmware, have you tried disconnecting the fax option?

I am assuming that you are cheating the door switch on the finisher to take the video.

As for the delay in responding to your pressing the status button, it is in part because the C4502 is still loading functions. After you turn the C4502 on, wait at least 5 minutes to allow all functions, including JAVA, to load.

I believe that the SR3110 also has a door on the top. If so, that door switch could be flaky. Usually it is one of those push button switches.

Sorry for my late reply and thank you for all your input so far!

On a previous visit I tried to reload the firmware but the machine immediately just says that it's done when I execute so it's not possible to reload current firmware. I went there today because a new System/Copy seems to have been released fairly recently (2.14) and that went fine upgrading (from 2.13) but the other ones could not be reloaded with the same version. JAVA is up to date, it's running the latest version 10.20.05.

Yes, I cheated the door switch with a piece of paper.

I am aware of the delay in responding when the machine is starting and loading the all functions but it takes up to 5-10 minutes before it's possible to open any menus and if I turn the power switch off the shutdown timer window never appears so something must be stalling/hanging the machine.

SR3110 does not have the door on top but the SR3100 has.

Today I removed the fax option from the controller but when I started the machine without fax option the exact same thing happens.
Also, while the finisher is going wild it does not stop if I open any covers or doors on the copier itself, the finisher just keeps going.
If the machine is powered off and I start the machine with the finisher cover open it starts like any other machine that is started with a cover open but when I close the cover the problem starts again.

I tried to start the machine without the controller in the machine but nothing happens. Only the blue led on the top right of the operation panel comes on but nothing else. I was thinking that the machine would start with none or very limited functions?

Looks Like a Short circuit either in the finisher wiring or the wiring from the socket to the pcb on the copier would be good if you had another finisher to try.

That's a fun problem. You did all the right things in troubleshooting this issue. I have several suggestions and hopefully it will help you on repairing this machine. I want to know what are the part numbers you've replaced for the finisher? What are the part numbers for PCB:STP: CONTROL and Main Control PCB?

In addition, re-check the dip switch settings on the old PCB to see if it matches the new board you've replaced. Lastly, I would downgrade the finisher firmware to 2 versions prior to the recent one. Also, I've noticed you cannot download SR3110 firmware off from TSRC?

I just checked. SD firmware is there. Remote is not. Both are on rfg-esource. One thing interesting, though the version number is the same for the SD card firmware on both TSRC and rfg-esource the date is not.

It is available for SR3100 but I don't see one for SR3110

The screen shot you posted is for the MP C3002/3502 not the MP C4502/5502.
