8518A C471 error

[buzz]

Reset FS 08-2002 to zero, but Code C471 keeps popping up. SM says to replace IH interlock switch, then fuser.

And any tips regarding this code would be great. I read the issues on C471s on 8508a and I'm hoping with this newer model things got corrected, though it's the exact same fuser. I went ahead and adjusted values as stated in previous posts regarding fans turning on sooner and what not. Also tested the IH cooling fan low and high (thanks blackcat!).

You're welcome. And AFAIK, it's exactly the same situation. =^..^=

Re: 8518A C471 error

Oh you don't want to get me started on this POS fuser. The 5540~5560 fusers would last a LONG time, so when they
made the 6506/16AC - 8508/18 series what did they change? The fuser.
The operating temperature of the machine is too close to the rating of the stupid fuse. Also, the belt holder is too weak.
Now, they've come out with a new bulletin (october) TSB-2078 that says to replace the springs in the belt holder, and
the alignment pins on the fuser. They claim the stonger springs will keep better tension on the fuser belt & belt holder
along with the larger in diameter pins on the fuser, will move the fuser just a little farther away from the IH coil.
Heck, you can't get belt holders since they are on backorder. I've updated about 2 dozen fusers with the new parts, but
it was right before the schools shut down for Christmas...I guess we'll see by the end of next week if they help.

Also, I've had REAL good luck ditching the stock eye dropper of lubricating oil, and using double the amount of Shin-Etsu
oil. Content | Shin-Etsu Chemical Company

This has pretty much stopped the belt unit from "drying out" and ripping the belt apart. Personally, the oil at room temperature
is very "watery". I think it really starts running out once the fuser heats up. The lubricating oil in the 4505AC series is a thicker
oil at room temperature. I've even thought about using that oil, but the Shin Etsu oil, along with dropping the fuser temperatures,
(Version 1600 makes about 11 changes) along with these settings, is helping.

(ONLY for the 8508-18's)

08-2010-0=13
08-2010-2=13
08-2010-10=11
08-2386=2 (fan speed)

I just created a policy and sent it out over the cloud. Yeah, it's changing the 85cpm speed machines temperatures down to 55cpm
machine temperatures, but we haven't seen any negative outcomes. Heck, most of these machines we have are in schools and they
don't run the monthly volumes on them anyway.

I'm HOPING next week we have a good outcome with the updated springs/pins because even in this "short" December month, just
my office has rebuilt 19 fusers.

Re: 8518A C471 error

We sent out a policy to reduce the speed on our machines as well. Luckily we have not encountered the nightmare you have with these models (knock on wood).

And on one of your other posts.. Don't get me started on the new FYI. I boycotted it right after it launched. In fact I posted about a mutiny on the site and suggested we all come to copytech.net, post was instantly removed and within 20 minutes we had corporate calling our office to speak with me about my insubordination. After that I quit playing their game.. 15 years of bookmarks and info taken away without a chance to backup or save, but I am in the wrong for taking issue
*shake my head* rant over.

I think they dumped it because we were coming up with ANSWERS to their problems and the support guys weren't doing anything. LOL
I know 20 years ago, someone said I should go to work for TABS. I said there is no way in hell I'd work for any "corporate" business.
I don't play those ass kissing games.

I see there is a new web meeting next week about PM'ing the EBN fusers...This should be fun to listen to.
Will be the same old same old...
"your doing it wrong, use all the oil, update firmware to latest"

The last 3 Toshiba schools I attended were a joke. We played all week. Never broke anything down and rebuilt. Watched some slides and took our open book test. I scored Top Tech, but never touched the fuser??? Anyway maybe Toshiba should look closer to home for the remedy instead of putting it off on dealers and techs.

In my experience some manufacturers are more interested in sweeping the issues under the rug, than fixing anything. There isn't a rug big enough to sweep this issue under.

I'm not sure why, but I believe that Toshiba is "committed" to this film technology, and for an unknown reason cannot go back to a functioning reliable fuser. =^..^=

Lucky for my company we have a secret weapon. Our service manager MarkG52 can Markguyver anything!

Can you say Samsung ?

I think part of it, is that they don't want to "admit" failure.
It's part of the Japanese mindset I believe. To admit failure, is to bring shame onto them.
Most likely, what they will do, is refresh the line in a year, and the fuser will be completely different, but NOT backwards compatible...
Gee...to fix the problem, you have to update to a new machine.

Yeah, I can't wait for the web meeting. I'll just have to make sure the mic on my laptop can't be turned on.

You are probably onto something. Speaking of different mindset, do you think the Toshiba copiers in Japan still come with blue screws? Blew my mind when I first started and was told what they were for, I thought to myself that would never happen here.

... I expect a complete line refresh around April 2022. Very similar product, I suspect Toshiba will transition from HDD to SSD.

No idea about any fuser plans.

Hope they do with the SSD's! Everyone else is doing it. Time to ditch the mechanical ones, not to mention the speed boost.
I would just swap out the old one's for SSD's, if it wasn't for the fact they don't have ADI and no one knows the "secret" code
to turn it off. I remember when they started with this. They said if it had a non wipe, you could upgrade it to a wipe, but once
you did, you couldn't go back. Has to be some sort of secret code to turn it off somewhere.

That or they are just hoping no one calls their bluff.
They just use corporate scare tactics to keep us Gaijin in line.
