Wich one 2 buy - CF8050 or C350?

Go for CF8050!

**NotByChoice** · 06-09-2008, 05:31 PM

We have a C351 with 500,000 copies. It has been problematic since it went over 400,000. It still works great under low usage but that's about it. These days if we put a couple thousand copies on it in one day it typically breaks down.

Thanks a lot for the comments, great! Perhaps I'll give the 8050 a try then... How is it, does anybody know if it's almost the same machine as the C500 model? It uses the same toner/supplies it seems...

**JSC** · 06-09-2008, 08:44 PM

The CF8050 is the same as a C500, do you know what Rip comes with the CF8050?
Personally from an engineers point of veiw if the C350 comes with a Fiery i'd go with that.

**Kanini2k** · 06-09-2008, 09:45 PM

Hi! Thanks a lot for your reply JSC, I was wondering about that one. Both machines comes with the Fiery RIP (unfortunately only the built-in/integrated one, is it called "piggyback?"), so I guess you would suggest the C350 then? The seller is also saying that it's a good and maybe better choice, I don't really know why?!? I think it could be more adjustments need to be made and so on, on the 8050/C500, the C350 is more straight forward, or?

One final issue I'm thinking about is the color matching/accuracy, could you say that it's easier to get somewhat accurate/correct color on one machine or another of these two given that it's the built-in Fiery RIP:s and not any coloritmeter etc. involved? Thanks a lot for all the answeres, keep comments coming if you come to think of anything else! I think it helps a lot in my decision to hear from you! =) It's hard to decide when price and everything else is quite similar (such as the saddle-stich finisher and RIP).

I would go for the C350 - less labour intensive maintainance and it is basically a 'hotted up' CF3102 so your tech will know his / her way around it without too much trouble.

**stacyrf** · 06-10-2008, 12:47 AM

Ok one thing about the c350. If it only has the integrated print controller, you will be unable to use Mac machines with it. Of course if you do not have macs this will not be a problem. If you do have a mac, you will need the external "piggyback" controller IC-401 for the C350 to work.

**laserman06** · 06-10-2008, 03:07 AM

Personally, I work on both models. It is true the the 8050/C500 are more labor intensive, but if they are set up correctly and well maintained they are a work horse. I prefer the C500 out of all of them. Your service tech needs to be well trained on them. Knowing how to do all the adjustments, is very important.

The C500 is an 8050 with modifications and improvements from the 8050. They do not use the same developer or toner. So the supplies are not interchangable.

I also do like the C350, but for a lower volume account that is only interested in business color. That is what Konica markets it as.

So again depending on what your customer wants and your needs are..

Just my .02 cents for what it is worth.

**Kanini2k** · 06-10-2008, 08:44 AM

Hi all! Thanks a lot for your fast and interesting replies! Hm, seems like it's both suggestions here. I would like to ask you laserman (or anyone else) if the set up on the 8050 is extremely difficult, or if it's possible to manage it with tryouts and a lot of patience? I'm doing the service myself on the CF3102 and that is no problem at all (of course it's easy to work on), so at least I'll try to do the service and set-up myself since I think it's interesting and fun to see if I manage... =) I am able to get the copiers for little money, so not that much harm if it's not working out. I am using the copiers/printers for my side business, but sometimes I do larger runs, and the 8050 seems more interesting right now with the 3-fold finisher and SRA3 possibilities, especially since I already have the CF3102 for shorter runs.

Do you think the supplies and spare parts for this 8050 model will still be available for some years to come, if it's replaced by the C500 and newer machines and they can't use the same toner/drums etc.?
Thanks again very much for your valuable answeres in this great forum!

Tips&Tricks CF8050

So I went for the Konica Minolta CF8050 after all. The seller said it could probably need a proper setup when it has been transported, and I'm first gonna try to make the set up (and perhaps some cleaning) myself. I'll get the technical service manual from the seller also.
Anything special in particular that applies to the 8050/C500/CF5001 that I would be good off knowing...? Have done services on the CF3102 earlier, but maybe there's some special tricks with the 8050? Thanks a lot again all of you who answered, this is a great forum!

**laserman06** · 06-14-2008, 01:01 AM

If you can get a copy of the theory of operations to go along with the service manual, might help. Then again, it might put you to sleep if you have insomnia.

Also the users manuals would be nice. My only advice is to get to know the adjustments. If you have any questions I will try to help all that I can.

**Kanini2k** · 06-15-2008, 09:35 AM

Thanks!

Thank you laserman! I already have the users manual in electronic format (even downloaded the driver to have a look at the settings, wich seems very similar to the CF3102, apart from more nice features! =) and will also get the hard copy with the machine. I'm going to try to get it up and running myself at first when I get it, and then if I stumble onto something very strange I'll get back in touch. I think it's quite fun to do some services myself (especially when they are successful!), and since I buy KM original spare parts and consumables from my KM dealer nearby, I'm not stealing his profit either.

Have a nice summer!

Now that you have an 8050...

You can buy your OEM supplies off of Ebay too. You can find toner, developer, and PM kits for 100K and 200K. JustManuals.com has a Konica 8050 service manual (original) that can be downloaded as a PDF at a VERY reasonable cost as well. Then you can just keep it on your computer for reference. The PDF is bookmarked and you can tab directly to Error codes, maintenance or parts with OEM numbers. With the manual, doing a PM is very easy especially if you've worked on equipment before. I personally love the 8050 model.

**Kanini2k** · 07-23-2008, 07:39 AM

Hi Juxta5, thank you for your reply! I have found some OEM supplies on the net also, but I get very good discounts from my KM dealer, so I think I'll buy the most from him. I got the original KM service manual from the seller who had it and it has helped me out a lot on the machine, since it is a bit different from the machines I've worked on earlier. I got it running recently, hadn't had time to work on it properly until now. Changed the yellow developer and now it's running well.

One thing though, I seem to get quite dark printouts (haven't printed many pages yet, maybe 40 pages or so), I need to use "toner save" mode to get a bit closer to "normal" output, but still some of the colours are darker than on other machines. It seems just as it puts too much toner on it, especially black. It also gives a bit of dirty background, so there's something that isn't right adjusted. I have runned the auto color reg., the automatic gamma adj., the gamma offset adj., gamma sensor adj., but it seems as I can't get rid of it. Maybe I need to run the adjustments again? Is it of any use to reset the data/settings before doing the adjustments, haven't done that?

I also set the switches 24-3 and 24-2 to correction not made, since it gave SC29-11 error code sometimes, could I run it with this disabled, or is this affecting the quality in the way described? Haven't noticed any difference with the correction on or off.

Thanks a lot! Have a nice week!
