Wich one 2 buy - CF8050 or C350?

[Juxta5]

Dirty background.

Was the "dirty background" on the test pattern that was output by the gamma adjustment (mode 36)? Also, my favorite setting while using the gamma adjustment results in the area between the two gray vertical lines (at upper left) being totally blank and the CMYK boxes just to the right having about an equal 2% screen of color in each of them. It isn't really until about the 3rd box to the right (of the vertical gray lines) that I can start to make out a box shape. None of the CMYK boxes on my gamma adjustment printouts show 100% color -- the very last vertical row of CMYK at the right is only about 10%. The result... VERY beautiful colors with fine detail. Though, I gotta admit it takes a long time to adjust all 6 screens (LS200, LS150, DS200, etc.).

Thanks for the tip juxta5, I'll have to really take time to do the settings properly and probably adjust it brighter for the things you said on the test patterns, thank you very much for the tip! Yes, the background occurs also on the test page.

I've just looked at the vertical CMYK boxes on the left side of the page (where they get brighter to the bottom of the page), and tried to adjust them so that the boxes between the grey lines was bright but visible and even, but now I realize that there's probably more to check on the page to get a good adjustment...

Thanks again, very helpful comment! Have a nice day!

Why buy another used machine ? There are some really great deals on new kit while the global economy has slowed. With a bit of research you would pay a little more but recover your investment more quickly. This is because the new Bizhub C253/353/451 all have longer service intervals than the models they have replaced. This all adds up to more cost efficiency in the longer term. Take for instance a new C253 complete with DF611 doc feeder and cabinet - Here in the UK you can expect to pay around 4761.14 Euro plus tax. Shipping would of course be additional to this cost. PM me if you need further help.

Hi Dark Knight! Yes, a new machine is of course the best option, but I kind of fancy servicing machines myself on my spare time and I got hold of the CF8050/5001 for a really, really low price (even if I do all the PM:s drums, developers and supplies etc., I wouldn't be even close to a new one), and since I think it's a more solid machine, fast (51 ppm), and with the trifold finisher, I thought it was a better idea. I don't print that much and I got other machines to run if I get in a hurry. The 8050 now runs great though, just need to adjust it a bit more to get the colours 100% right.

I got an offer from the local Canon dealer (after a looong wait), but their price per copy was up in the clouds (about what I pay if I go to a local print shop with no discount, so why buy a machine then?), and then the purchasing price of the machine was in my opinion quite high also (they offered a package with servicing etc. included). I also asked them for a used one in the same league as the CF3102 at first, but the seller didn't bother getting back to me even after asking a few times, so if they don't bother then I shouldn't be wasting their time(?) and instead stick to the Konica Minolta since I'm very happy with that brand...

Hi again!
Now I have a tricky question; when printing as normal the print gives a dirty background that's very even black dust on the whole page. I've tried to adjust the gamma and reset it and adjust again but no luck. BUT when I print with "gloss" mode in the driver the background is gone and the colours are great! Of course I could use the gloss mode all the time, but why is it like that? And is there any tips on getting rid of the background by adjusting? And Juxta5, I've tried to adjust the gamma adjustment very bright, but that doesn't seem to affect the background at all? Thanks very much! I enclose the pics from the printouts with dirty background, doesn't show that good but you can see the difference from a white paper on the config page.

You have the Fiery print server which changes everything. Please apply all of the updates (in order). You can do this the old way or click the link in the Fiery print driver (install from Fiery's web site). Also, do you have the correct print driver (install from the web tools) installed? After doing all of the updates and it still does it, you might want to run the copier and then fiery calibrations over again.

Quick question, on this machine- when you go to the copiers web interface does it flash "setup warning" and an Explanation Mark on the top of the page where it shows the copier status (i.e. low paper)?

c350 and c8050

I recently bought both the machines. I was able to set up the c350 and network. But, I could not be able to network c8050. I can ping the network and it shows the IP address but it does not print a test page. I downloaded the driver from Konica/Minolta website for windows xp and installed and uninstalled few times but still it is not working. Is there a special way to set up the network on this machine? Also I got two plate to hook up the sorter with the machine but I don't know where to screw them. I called the mechanic but he did not know this machine. Is there anyone who can email me the instructions or sketch or service manual and service handbook? As the other people gave their views about the machines, I do believe that c350 is for the shorter run whereas the 8050 is a workhorse. My email is print_post@hotmail.com. I will appreciate the gesture. thanks

8050

Ok

I work on both and they are two totally different copiers.

The 8050 is the generation before the c500. It is a production copier and has a fiery controller. If there are problems with quality of output, you will have to call a pro to work on it. They have a 100k pm. Pms could run upwards of 1000 dollars just for the parts. They were also not known to be very reliable.

350. Business color. Usually did not have a fiery and yes you can use a mac with the standard controller. There is no pm cycle for this copier as all the parts are usually very easy to replace. Were there some bad ones, yes... but it is usually a very good copier.

[NotByChoice]

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.

It's been a year since that post I made (the one I'm quoting) and around the time I made that post I replaced all the replaceable parts and had a tech come in and do all the adjustments and alignments and it has been run a lot better.

It is now at 750,000+ copies which is about 20,000 per month since last year. It's still going strong with just the minor issues that all copiers have. And we've probably saved around $15,000 during the year by not having a service contract.

My only issue with the C351 now is that Konica Minolta does not offer recycling for the parts/IU's/toner. Whereas HP does. And HP's are cheaper to run.

Networking an 8050 w XP

I recently bought both the machines. I was able to set up the c350 and network. But, I could not be able to network c8050. I can ping the network and it shows the IP address but it does not print a test page.

What I do is change the IP address on the machine to be in sequence with my business network. Then I go into Print Manager in XP, highlight the printer, go to Properties, Ports, Configure Port then manually input the correct IP address.. ie:

Port Settings:
Port Name: 192.000.7.103
Printer IP Address: 192.000.7.103

Technically I could put whatever I want in the port name, but I've noticed that the XP PS printer driver works best if I just put the IP in there.. wierd. :P

You will run into trouble from time to time if you are running DHCP... the network hub can & will re-assign your IP addresses on occasion so you won't be able to print. So I would set up a static network.

c8050 networking problem

I tried to change the IP address on the machine which is now 192.168.2.30 and I changed that in the properties port config to same as on the machine. The port name still shows 192.168.2.90 (the previous IP address). Did not work. I also tried to download another driver and it still did not work.
Then I deleted the printed and driver and downloaded a new driver from konica website:
software drivers/printer drivers/konica drivers/color print systems/8050 IP901, 921/IP 901/windows/3fold and booklet/ 20aupt1du4r6s1.exe
add new printer/tcpip port 192.168.2.30 have disk and driver file. still no luck.
on the machine i changed the dns to 64.59.144.16 and 64.59.144.17 (my internet providers dns address). I did not enter any domain name which is blank. host name is konic8050.
My router gateway is 192.168.2.1.
May be I am doing some wrong settings. If you have a fax number I can fax the machine's configuration to you.
I have EFI fiery system 5.5e version 1.1. Fiery S300 50C-K v1.1
According to the manual I received with the machine (I am not sure if this is the original manual that came with the machine) Its IP901. Thanks for your time.

You have not said what controller your have, is it the one in the back of the machine or a stand alone blue computer?

Some of the Fiery controllers have 2 network ports and will not print if you are using the wrong one, we usually put a dummy rj45 end in the one that is not to be used

In fiery setup under server setup, you will find something like "no account printing" turn that on. just in case there are accounts setup on the copier.

While you are in there, check under network settings, that port 9100 is turned on as this is the default port for printing from windows

Can you print the configuration page from the Fiery? if so post it and we can see whats setup correctly

cf 8050 network problem

Thanks DUDLEY
With your help I was able to setup the network. It is working fine. It was just the service setup and port was off.
Now I have to hookup the sorter with the machine. I have got two metal plates with the machine and don't know where to hook them up. I will appreciate if you or someone would kindly let me know to install these plates. If someone have drawings/or a service manual, please email me at print_post@hotmail.com.
Thanks

Just wanted to chunk in how thing's been going for me. I had a troublesome start getting to know the 8050 inside out, but today I've learned the do's and don'ts of the machine. I did have to change developers and so on... It runs really great and has a great build quality and really is a workhorse. Compared to the Bizhub:s it's much more sturdy and as pointed out more of a production machine. I really think the output is really great and it's quite fast. Of course there is newer machines coming all the time and an upgrade may be in sight but for now it's ticking out great output so it stays...

[hachetman]

I have worked on both modles for 4 years now the 8050 was marketed by Ikon hence developer and toner is not the same as the c500, all other parts are the same, i would have to agree that the 8050 C500 are very labor intense but if your tech is good wow the final prouct this box is capable of, (productions box) The C350 is great for office color with good qualty paper you should be able to proudce decent copies/Prints
It all depends on your needs!
the C8050 dose cost more to maintain and operate
