[Error Code] Bizhub 361 CD203 error.

[mjunkaged]

Hey, all:
I have a biz 361 that threw up a CD203 while I was testing feed motor M9 for a feed section squeak.
I have tried holding down the utility key and doing a trouble reset, as well as put in a recovery firmware CF card. The existing firmware seems fine, and functions as it should except I can only access the 1st service mode screen, and pushing any desired menu buttons on touch do nothing except display a 'please wait' message for over 1 minute.
I have also removed the LVPS and ohmed out the 4 24v hard-mounted fuses, and the 120v fuse is also obviously fine if I see a screen light up!
The STOP-ZERO-CLR brings up that menu list, and I tried executing a couple things in there, but still the error persists.
I think the PRCB, and possibly motor are both bad. I wasn't sure if I was doing the recovery firmware CF properly, as I don't seem to have any instructions for it. Any help before I start ordering parts would be appreciated. I wish there were a 'warm restart' switch someplace on this model, like there is on some of the older units!! Is there? I can't find any reference to one, or a jumper.

Re: Bizhub 361 CD203 error.

Do the firmware upgrade or same version via USB. Could be a problem with the firmware data on the OACB and PRCB not talking they way it should. Could have been triggered by directly accessing the hardware output somehow. So my first guess would be the OACB is not responding to instructions because of firmware data corruption on it.

So i would think change the OACB first if you are going to change something.


But that is enough of my senseless theories.

Try reflashing the CF card...

Done, writing a new card didn't work. Can NOT access the ISW menu in order to use a USB stick. Recovery FW did not work either. I have replacement boards, and a motor on the way. I'll post a follow-up.

FYI: If your machine has an error that won't reset, your USB stick will be useless if you can't access the menu.

Re: Bizhub 361 CD203 error.

Take your time to read thru the entire ISW section in the manual concerning boards. Those motors are robust so not sure if that will be damaged.
Also look at the notes under "list of adjustment items" in the manual.

I have read and RE-read those sections, unfortunately, if you'll read my post, I've waited 1, 2 , 3+ minutes after pressing the menu buttons in service mode and it continues to say 'please wait.........error CD203.

The stop zero clear CE clear menu does function, but not the first set of buttons on the service mode screen (counter, system1, system2, etc. OK????) Unless I''m missing something, I'm getting old and slightly blind, so if you have an answer, you can give it to me and not make me hunt for it.

Or I can just go fix the machine and get back to you all. Should I wait TEN minutes after each button press? I don't have that kind of time to waste, I'm not working on it at the shop. Hope I'm not coming off rude, thanks for trying to help!

Meaning that you know what to do when you replace these boards. Understand its currently a brick.

Just trying to help...
In this case i would try my best to get the machine to give a different error by unplugging stuff. Does the control panel go dead if you disconnect the OACB. I have this weird way of trouble shooting that seems to work for me. Sure i come off as an idiot sometimes but at least i get stuff fixed as thick as i am.

Something to chear you up.

Yeah, I tried disabling different things also..........before I threw up my hands in disgust and posted for help. All my Kon-Min tech. support people were on vacation for the holidays....rotten timing!!! I've found used staples in this machine, and may have bumped the connection on M9 while it was live but not running near the connector on bottom of motor PCB. I'm aware that NRB and CF contain all my customer's machine critical info, and I'd prefer not to wipe it all out as I'm pretty sure it ain't gonna fix it. Just make more crap to reprogram. Do NOT want to lose counters, in fact, I enabled counter backup to CF function while I was in the only menu that worked under service mode (user touch menu is fine, it's any button on the screen of menu choices AFTER service menu it says "duh please wait" for eternity. Sorry I wasn't clear about that part.....I also experimented by inserting different versions of 361 FW on CF cards, which would not even boot past hourglass screen. I'm going to find out if it was PRCB or OACB or BOTH that took a dump (regardless of what or who killed what) and post a follow up. I'd kill for a soft restart button, especially if I thought it would work.

Re: Bizhub 361 CD203 error.

Let us know what the result is. Its an old machine right? They run well but a little on the fragile side looking at the units. Not to mention the toner supply patent on it.

Lucky enough to avoid them for the best part, never changed CF cards or firmware on these unlike my experience with the bigger brother the 601/751 konica POS.

Standby sucks if all the suppliers are closed for business...

C-D203 at power ON and the code may not reset.

Root Cause
1. The OACB (Overall Control Board) has failed.
2. A poor connection between the scanner drive motor and PWB-SDB.

Workaround/Fix
1. Before replacing the OACB, reseat the and Memory on board connections. If the issue is still unresolved, replace the OACB (p/n A0R5 H010 06).
2. Reseat CN62 on PWB-SDB. If the problem persists, replace PWB-SDB (p/n 50GA -905 0).

I did number one, it was in the SM. 2. was not in the manual, I will check that as well.

Re: Bizhub 361 CD203 error.GONE.....but.....of course....NOW need to do TCR

Hey all:
SO, I went back today, and sure enough, I could not get the 'please wait CD203' to go away or allow me to access Svc. Menu functions (only the screen, and stop 0 c functions) even after trying different OACB, NRB, etc.

AFTER I replaced feed motor and PRCB, now I HAVE ACCESS TO ALL SVC. MENU FUNCTIONS on BOTH OACB's!!! Please wait is a few seconds. I had to clear all counters, as backup had never been turned on (you can backup counter data on this model to CF card but have to turn it on at least one time slot per day).
Then, I was able to recover the corrupt firmware AND NRB (didn't see that one coming, my last bad nrb stayed bad-blown) by using my trusty USB firmware.

So, hopefully, I can put in new developer and adjust TCR when it arrives (MUST BE DONE any time counter is corrupted/erased), and re-setup all the time/date, network, machine adjustments, etc. etc. and finish the repair. I'll post again when (Hopefully not 'if') it's done.
Thanks to you guys that helped during the holidays!

Yeah, I seem to have a talent for 'bricking' this series machine, and from what I've read, some like to randomly down themselves with errors.
FYI, default setting on these is to NOT set a regular backup of NRB counter data to CF card, but I'd suggest if you have any 361/421/501 series that you want to NOT lose all counters then turn it on!! Too late for me and my machines, I didn't even know that was an option/might be an issue until I pored over the manual 4 or 5 times just this past couple weeks! But, if you ever want to 'zero' your electronic counters........just have spare boards/mem/NRB on hand!!

Things I've learned:

1. NEVER unplug the NRB from OACB until after power has been removed for at least ONE MINUTE!! Yes, I did that once.
You'll sometimes need to get a replacement NRB sent from Kon-Min to fix the unit if your used ones won't work.

2. Pretty much any time you have covers off, no matter how busy you are, better unplug the machine, or at least SW2 OFF. These things are SO touchy, I think it may be susceptible to static discharge in places you'd never imagine, like way down by a motor harness?? In other words, you don't have to touch the boards, just anything wired to them!!

3. BTW, NRB replacement wipes ALL your setup settings, and not sure if the above mentioned backup works for only counters or machine settings as well....anyone???? I did try a recovery from the working counter data in the swapped NRB but it was a FAIL.

I would have given up a lot sooner and replaced it wit a used 363 machine.
