Grr. Part II: Canon IR3200-C1 duplex registration issues

[dada2199]

This is part II of my ongoing duplex registration issues with the Canon IR3200-C1 that recently replaced my old NON-C1 Canon IR3200 that was ruined in a flood.

I've:

1. Cleaned and checked out the ITB (seems fine!).
2. Ran the automated duplex tray calibration for every tray using the "Printer" (C1) Tab on the main menu. It's within 1/32" in the X and Y axes.
3. Printed duplex from Adobe Acrobat Reader, CorelDraw, Illustrator CS5, and Word, using Canon's UFR and C1 drivers from their website (latest versions for both).
4. Printed from different workstations using different driver revisions.
5. Tried a variey of paper stock brands (Hammermill, generic Staples brand, HP brochure matte, etc).

No matter what I do, duplex is still off in the "X" axis (what I call the short side, or the 8.5" side of a letter sheet).

It's not just off a little, it's off a TON -- about a solid 1/4". We do plenty of short run proof booklets locally, and having proper duplex alignment is a big deal when we face trim.

Any thoughts what I might be missing? My old IR3200 (NON-C1) never had a single problem with duplex registration.

I think I might consider "lying" to the printer next during the duplex tray calibration stage, just to see if it makes a difference or not.

The printer was maintained by Canon up to recently via the previous owner, and everything internally looks solid and clean -- WAY cleaner than my previous IR-C3200.

Thanks for any advice, help or criticisms!

Doesn't hurt to attach an image. This was a rectangle designed in CorelDraw (16" x 10"), perfctly centered on the page, printed duplex.

I folded the page over itself along the X-axis (17") so that you can see the misalignment. This was printed 1 minute after I ran the C1 RIP tray alignment option.

According to my measurement, it's off by 1/16" on 11x17. On the 8.5x11 it's about 1/8" - 1/4" off on the same axis.

This is it, Teckat. You save the day again!

I just grabbed the Canon Driver Configuration Tool and am about to dive in and break things.

I've never done a duplex copy from the DF, so I'll test that, too.

Thanks again! I'll report back!

The copiers never come from the factory properly adjusted for bang on duplexing. Most customers doing letters never notice that it is off. There is a !% of customers for which this is a priority.
I started on copiers as a shop tech for 5 years. We had to setup all our machines the way you want it.
I got tired of it and went in the field. Now I only need to do those adjustments once every 5 years or so.

If memory serves me right, Try adjusting registration till both sides match ( copy> adj> Feed-adj>Regist). Some models have duplex adjustments.
for horizontal registration ( C > A > FEED-ADJ > REFE )
To do it right you really should start by alighning your cassettes first, then duplex then fine tune with fiery.
That's why I said in your first post that I was giving you the short cut.

Thanks, Vigour!

I'm in that adjust menu now (and taking notes of what I do for the next time I replace this beast).

Do I have to reboot the printer/C1 every time I adjust in the service menu?

Thanks for the reminder Teckat.
I missed regist2 when i checked my manual, because it is listed under CST- ADJ.
I had a feeling there was something of the sort , thats why i said some models have duplex adjustments.

i do not think you have to reboot after making those adjustments.
to check, max out one value , do a test and see if there was a radical change. if no change, then you have to reboot.

Re: Grr. Part II: Canon IR3200-C1 duplex registration issues

I'm back again, working on our duplex alignment and registration issues.

I did what was said above and it's a LOT closer.

REGIST/ADJ-REFE/REGIST2 all set to values that make the front side perfect, but the back side is still off significant on the short side of an 11x17. Basically, if I fold the 11x17 into 8.5x11, everything is aligned. If I fold it into 17x5.5, the front side is perfect but the back side is off by 1/4" or so.

REGIST/ADJ-REFE/REGIST2 do not change the "horizontal" distance for side 2 whatsoever. I'm assuming I'll have to pop into the duplex adjustment screw, but I'm having problems locating it. What's the best way to get access to the screw?

Thanks for the help -- we're a LOT closer than we were ever before!

Tray alignment on the fiery should take care of that.

Re: Grr. Part II: Canon IR3200-C1 duplex registration issues

I actually did the tray alignment from the C1 printer settings menu twice already -- it prints its own calibration page perfectly (within spec), but when I print from any Windows app duplex, it's still off along the horizontal.

Any other thoughts?

Re: Grr. Part II: Canon IR3200-C1 duplex registration issues

do your alignment within the App u are using for document

Re: Grr. Part II: Canon IR3200-C1 duplex registration issues

That's a curious option -- meaning I should do the actual "tray calibration" and C1 print settings calibration based on what's coming out? Seems to me that would skew all the other programs we use.

I'll give it a shot though, but I'm confused as to how the software would make a difference.

all apps have these adjustments but remember this is a COPIER

factory alignment is only good for most offices.
print shops and 1% of offices make you earn your pay by finding all the possible adjustments.
do a pg5 on your machines and see how much difference there is between each cassette.
luckily most people do not use the doc feeder, because that triples the work.
