Bizhub 283 C1004

Re: Bizhub 283 C1004

So the 223 I put in place of this 283 had a finisher C-1191 problem today. I can see the piece that is out of position on the FS-529. What I did was take the finisher from the 283 and put it on the 223 and it works.
That means the issue with the 283 is not finisher related right?
That means I can forget about the CP1 and the R1 right?
Should I still look at the CN83 A and L?

Re: Bizhub 283 C1004

Correct, not finisher issue. Perhaps PS, perhaps MFPB.

Re: Bizhub 283 C1004

I feel like I am going to be a real copy tech by the end of this lol Where do I send the check?

CP1 = 5.00
CN6 pin 2 and 6 = 24.11

Is that CN6 reading good enough to determine it is not the power supply, but the MFPB? Or should I swap the power supplies just to make sure? (I was going to try that today, but they had different numbers on the sticker that looked close enough to part numbers so I did not try it).

My final question concerns the CN83. Is it the white connector in this photo what I unplug and measure? The leads won't go far enough into the beige piece below, which is what the FS-529 plugs into. After thinking about it. CN22 goes to CN83. So it has to be the white connector.

Re: Bizhub 283 C1004

The idea is to track the 24vdc from the PS to the finisher controller. Since you have 24vdc at CN22 the PS is fine. This also rules out any dead shorts to that same 24vdc circuit.

Did you say that the finisher worked on the loaner? That rules out any problem with the finisher. Just make sure that the finisher firmware is at a compatible level.

The logical choice is the MFPB, or the harness from the the MFPB to the finisher. You can pin-out the harness easily enough.

Do you follow my logic? =^..^=

The harness? Is that the CN83?
Not sure what pin-out means.

Re: Bizhub 283 C1004

When you pin-out a wire harness, you're measuring resistance (preferably 0 Ω). You identify the proper connector on the finisher and the proper connector on the MFPB, and measure resistance from the pin on the finisher end to the pin on the copier end. I find that it's useful to make a chart on paper, then check them off as you go:

As an example:
Finisher: CN100 MFPB: CN3
Pin1 Pin3 0 Ω

The hardest part is finding the first connection. The rest are usually sequential. If you find a pin-out that's more than 0, possibly ∞, that could be a problem.

The thing that usually throws me when I'm pinning out harnesses is when the meter misbehaves. Occasionally check meter pin to pin to make sure you're getting 0 Ω. A bad meter lead or a bit of corrosion on the meter switch contacts can make it read wildly different. You're meter may be new, but for most of us the meter has been ratting around in the toolcase for at least a decade in highly humid conditions and temperatures from -10F to +100F. =^..^=

Re: Bizhub 283 C1004

Thank you very much.
The MFPB CN22 runs to CN93 connector that connects to CN83A on FS-529. I want to test CN22 and CN83A? Those pins are
1-6 TXD 2
2-5 GND
3-4 RXD1
4-3 GND
5-2 CTS
6-1 RTS

Yes, correct.

Re: Bizhub 283 C1004

Thank you. when those come back 0 I'll replace the MFPB?

I got the piece back in place on the broken FS-529. Getting the lift tray back in place is proving difficult. I broke one of the clips the manual calls "roll" on the upper shaft, not the one I removed. I got that one back in place. I can't get the thing to lay back down.

How do I get a setting to stay changed, like background removal level? Like ona Canon I have to go into the settings/registration to get the change to stick. Is there something like that for Konica also?

Re: Bizhub 283 C1004

I may miss a few keystrokes but it goes something like this:

Make the desired changes in the copy screen. Go to Utility > User Settings > Copy Settings > Copy Defaults > choose Factory Default or Current Settings > OK. You have to be quick enough that the machine doesn't default back to the home settings before you get it locked in. The same goes for scan settings (except ... Scan Settings > Scan Defaults ... etc. etc.). =^..^=

Re: Bizhub 283 C1004

Thank you for that! Got the broken finisher back together and ti was working when I left. So i can get back to the borken machine with a working finisher.

So these two items are on opposite sides. I can't see them both at the same time. How do I get my leads on the pins? The CN22 is behind the frame in this photo. Oh I guess I could unscrew the plug and maybe pull it out, that's the bottom red arrow which I guess is CN83 from CN93.

Re: Bizhub 283 C1004

I think I tested all 6 today and they were all 0. But I discovered what I was testing was CN22 on the PRCB, not MFPB. I am supposed to be testing something that connects from the MFPB to the FSCB? The wiring diagram shows it connected to the PRCB.

Re: Bizhub 283 C1004

If it goes to the PRCB, then that's the board you'll need to replace. Be sure to follow the directions in the manual. It's not just a swap. =^..^=

[copierknob]

Re: Bizhub 283 C1004

Yes the manual indicates I have to rewrite the firmware to the latest one. I already have that as I tried that as a fix. It says to move the EEPROM. Does that just pull off the old board?

It also says:
"When the EEPROM (IC51) is replaced to the brand new one, the error 'License management error occurred' will be occurred.
In this case, it is necessary to repair the i-Option license management information"

What does that mean?

Yes. I use a Husky branded Tack Puller:

It means that you should swap the old EEPROM to the new board so this won't happen. =^..^=
