Dulpexing: Auto vs. Manual Pro's and Con's

[SnappySteve]

We duplex 100# Gloss cover all day long on Oce CS665 and CS650. Registration is generally 1/2 mm if we run a Both Sides adjustment for the stock. Sometimes you have to outsmart the spec, sometimes the machine won't do it. As far as those machines (equivalent of KM 6500/6501) they will do it if you keep the machine adjusted right.

We almost always encounter skew discrepancies on attempts at manual duplex. That has been our experience with X boxes, KM, and Océ - just does not work well.

Sorry to take so long in responding. I have had several things come up that have delayed this project.

Still needing a machine... we are leaning towards the IR 9065 but wanted to quickly make sure that people have been able to auto duplex 11 x 17 100# cover out of the attachable side pod/paper deck (not stack bypass)?

We can't justify spending the money for the IP 6000 if we only need it for it's ability to auto duplex 100# cover. However, if we are going to have serious problems after the first year on the 9065, then we might get the 6000.

Anyone with personal experience on these?

There are really good deals to be had on KM C6501s these days, since the new 6/7000s came out. It's a good box and will run that stock all day with tight registration once you get it dialed in. What market are you in? I might have a lead on a lease return with a dealer in our network. Not all those were "rode hard and put up wet" in a hardcore production environment; cherries exist that lived lives as office/church copiers, the result of overselling (AND overbuying!). Not a ton, but some. Worth a look.

>>>>>Note that if you work & turn, that stock should NOT be treated as the same stock it was on the first side. Spend the time getting the registration tight AND the transfer settings. And remember that if you have one side with heavy fill it should be run FIRST in most cases. This avoids mottling.

WADR to Steve, the KM 6500/6501 are not "the equivalent of" the Océ models. They're exactly rebadged Konica Minoltas. YMMV on support; when I was at Océ, the techs knew fuqall about KM production machines and treated them like big copiers. But then, I've seen KM branches with similar deficiencies. Like I said, YMMV.

I would not jump into a machine that does not support the paper stock your needing. If you get into any kind of issue with image quality or paper jams the printer manufacturer will just blame the paper stock. You would have to duplicate the same issue on a approved stock and if it does not duplicate you would be SOL. Tricking the machine works if its the exception but if this is your house stock I would think twice about it.

graymatter, Thanks for the info. on switching the settings for the side of paper stock. I did not know that. Were down south in the Dallas area.

I had a KM sales rep come out and show me the doc's on the 6/7000's. He is putting together a quote. I will have to ask him about the 6500's.

arossetti, Our default stock at the moment is 80# b/c that is the machines max. We want to move to stock 100#. That's a good thought with duplicating the issue.

Does anyone know the real PPM using 100# duplexed in the Canon 9065 or the Canon IP 6000?
I understand they will slow down considerably when running that.

It seems to me that we are right in between a commercial grade and a press grade printer. The commercial grade will almost do all of what we need and the press grade will do more than what we need. Given your experience, where would you go?

Also, if I am just going to be sending PDF files to the printer, what type of controller would do that? Standard one that is on the machine, external, stand-alone, etc.?
