I 'm just considering to change my old C6500. I'm really interesting in the new C7000, but the SD 506 (saddle stitch) seems very expensive, and other finishers of konica can only fold up to A3 paper, same as what I have now.
Last week I got a news from Ricoh that they released a new model C751ex, so I went to test the new machine. The result is not bad. It can fold SRA3 paper and staple directly and the registration is very very good. Just the colour is not glossy as C7000. And the price of C751ex seems very competitively.
Don't know how to choose...give me some suggestion please, thx.
We just purchased a KM6000 and have been very pleased with the quality of print off the engine. One area that has been a problem for us has been sheet to sheet registration. We also run Xerox 700's and they hold much, much tighter registration for front to back as well as sheet to sheet.
On the KM 6000 we're getting as much as 3mm difference...something I'm told should be much tighter, by the sales monkey as well as the technician.
I've attached a photo showing a stack of 12 point stock we printed (jogged in our paper cutter so the edges are all flush) the variation in the print is seen from the edge of the stack.
The SD 506 finisher is worth the money. We have one on our 1200 and have put close to 10,000 booklets through it in the last month and a half. It's a beast.

3mm is unacceptable. Call your tech and tell them to fix it.
If he can't you need someone with experience.
If the lead edge is varying more then 0,5mm to 1mm then something is wrong either with engine or your tech.
Have you tried to reduce or increase the paper loop?
Basically for heavyweight paper you need to reduce the loop, and for light need to increase it.
Check this, ( this taken from u8ertech C6501 book) it may be useful for you.
"The c6500 (C6000) uses a loop system to insure good registration. This is made up of a large rubber roller and
steel roller pressed against each other using springs. From the factory these springs are set to the
lightest setting. At this setting the registration is not 100% effective especially on heavy stocks. There
is no way of visually telling if the springs have been adjusted without disassembling the reg unit. If you
have found after preforming the restart timing adjustment that the registration wanders more than
1mm you should probably have the unit checked out. This adjustment does not appear to be common
knowledge. However even with this tension increased some stocks may wander but this is pretty
uncommon."

But sd506 only can do face cutting, the ricoh trimmer can do 3 sides edge cutting, of course it is also expensive.
My opinion is that ricoh normal finisher can make booklet from SRA3 paper, but if I choose Konica, I must have the expensive SD506, which can only do face cutting. That's really not a big difference to do 2 or 3 edges cutting for me.
our technician looked everything over and tightened the registration on our KM 6000 up some, however it's still not as good as our Xerox 700, the worst part is I'm being told there is no skew adjustment on the machine, and our main problem now is the skew on the sheet. We've gone through the alignment setup on the machine and we can get the sample prints looking pretty good. We'll print out an actual file and the first few copies look good. However if we run several hundred and then cut them you can see quite a bit of variation up to 2mm sometimes, the lead edge (gripper edge) is very consistent, the tail edge moves up and down a fair bit skewing the print on the sheet.
After all this the technician states that's as good as it gets, naturally we were not happy and have since talked to our salesman to get this issue resolved. They are currently looking into it. I showed him the documentation on the registration roller that was posted previously but apparently he thought it was greek since he did nothing with it.
Does anyone have something similar to a CED (Customer expectation document) for the KM 6000 printer? I would be interested in what they are guaranteeing for this machine.
I can't believe they claim that is as good as it gets! I'd personally throw that machine in the street if it were in my shop!
We run Xerox machines here and I showed your photo to our sales rep and our tech and both agreed it sucked (but you already knew that!). We all got a chuckle out of the comparison to the X700 registration because we think the X700 is loose (we are used to .5mm). I honestly don't see how you are selling those prints. Guess I don't need to look at KM on my next round of upgrades.

I can't believe it!
X700 is great machine, but C7000 is also great.
Can you please tell me which configuration you have C7000 with PF-602 or LU-202?
