Savin 8055/8060 SC542

[unisys12]

I have about twelve of these at one location. Three of them are in similar environment, in that the customers run a lot of single page jobs. Like several hundred single pages a day.

This is causing toner to build up on the thermistor, since the web is not cleaning properly. Knowing that improper web cleaning is causing the problem, due to the high number of single page prints, I increased the web motor on time slightly. Well, actually the first adjustment... I thought was slight, but the web ran out two days. LOL! Anyway!

This has helped cut down the SC542 incidents to around one a month now. It was twice a month for each machine. We are also having to replace the web at about 175k -180k.

What I'm wondering is if anyone else out there has any better ideas. I would love to get rid of the problem all together, but I know I probably wont. Just hoping anyone out there has any suggestions.

As for the rest of the machines at this location? Well, they all print fairly large jobs darn near constantly. The majority of their jobs are more than 15 pages per job and have no problems such as the three I mentioned above.

I don't have any of these models, but I have quite a few 1075 Ricoh's (they are inexpensive from the wholesaler and work well.)

Anyway, I usually increase the web supply on these a bit higher than the factory settings due to the inconsistent copy jobs. There will be days that a machine will see 8k, then suddenly see a few hundred if everyone just needs an occasional copy. I have aftermarket webs that are about 10.00 and they work great. I don't mind going out and changing a web to avoid other issues.

I'm not sure if the aftermarket has the webs for these yet. Given the buildup on the thermistor, I think that trying to slightly increase the web supply is probably on the right track. It looks as though you wouldn't be visiting them too often, unless you crank it up.

I know that on the 1075's, there was an old firmware upgrade to help adjust the web supply, as it was hitting the 550 code too quickly. I don't know if these models have a firmware update for something similar or not.

Others will have better info, as I was just brainstorming a bit. But I would probably turn it up just a bit too.

Hey! No way! Brainstorming's great. Talking out load even. I just wish I could get some of the guys at the shop to brainstorm this one with me.

It's one of those accounts that none of our guys like to go to because there's so many machines there and since I'm in that area more than most of them, I end up going more than they do. When I have a tough problem there, everyone just shakes their head and walks off mumbling how much they hate the account. Oh well... that's a whole different thread all together.

Anyway thanks! At least I have one vote that I'm one the right track.

You need to make sure all the filters going into the body of the machine are clean because that can cause heat buildup inside the body and give SC542's and blow the thermal fuses for ya.

Got that word a couple years ago straight from the mouth of a Ricoh rep.

SC542 happens sometimes during copy cycle and sometimes during warm up. Performed the following steps to minimize the occurrence of SC542but without success.
* firmware updated * thermostats replaced (RB246021)
* fusing harness replaced * AZ24 0112 Power Supply Unit:EU
* B247 5122 PCB BCU * B247 5128 PCB IOB
* AW10 0109 Thermistor - Inner Back
* AW10 0108 Thermistor - Middle
* AX44 0216 Heater:230V:550W
* AX44 0217 Heater:230V:650W
* AX44 0218 Heater:230V:280W:Auxiliary
Cause:
To simulate a toner crust on the thermistor surface we inserted a piece of paper between hot roller and thermistor to cause an SC542
Therefore we think that the MT C3 is too sensitive for variations in temperature.
Action:
Changed the value in SP 1-107-003 from "60" (default) to "120" and has been successful with it.
SC542 has never occurred since changed the value in SP1-107-003.
I came across this fault and found this useful. hope it helps.

Thanks for the tip Stig... I will look into it further on Monday.

By the way, shouldn't your profile pic be this...

Man! I love Top Gear. Even if they do make fun of us Southern states folk. LOL!

unisys12,
Sucks that your fellow techs are too "sorry assed" to participate in this. Here, we brainstorm pretty much everything weird. Not sure, but I think the underlying reason is because we all want to be the smart one who came up with the answer (healthy competition).

As for your problem..........3 of us still brainstorm it from time to time (we have had issues like this on a few of these, and a few prior). I think web control is one key. I have another theory, but am still researching. (Still thinking on it. But in the middle of a merger, so no time lately.)

Take a look in service mode for something that refers to fuser idle time before copying (not sure if you'll find it).
Play with that and see what happens. (Yeah, and keep filters clean too.)

On a side note: The sad thing is that your customer has an umteen thousand dollar race horse pulling a kid's pony cart. And YOU have to make the horse fit the cart, LOL!

Until later,
Regards

Well thank you for your concern. Yeah, we have a load of piss poor tech's, but I'm different then them, so...I rightfully shouldn't expect each one to react just as I would, I guess.

I keep telling myself that, even though I'm not the service manager or anything that like. Oh well, again... that's another thread all together.

Thanks for the tip on the SP. I will look into it on Monday morning and go from there. All these ideas will keep me busy for at least the first hour or so of work on Monday, so this is great stuff for me.

ha ha lol. love the picture of "the stig". yeh I like top gear too, i'd love to have a go at driving a car around that track with the real stig...but does he really exist or is he just a legend??????

Many techs i know use this and have found it sucessful, be warned some customers will not want a 120 second wait so may have to find a happy compromise.

I should be able to make the adjustment through @Remote, so I will give it a shot in the morning. If all goes well, say three weeks or so without a SC542, I will then slowly adjust the web motors back to default.

Thanks guys!!
