I am trying to print the maximum sheet length of 37.75 inch sheet. I've tried double sided, single sided, and turning down feeding fans. Getting 3-5 mm skew....even when running 1 sided. I wouldn't say its consistent each sheet. Tried running the auto calibration and it doesn't help. Ran manual adjustment by measuring the sheet with no help. I have the side fences and back guide installed in the paper tray correctly...i believe. Does anyone have any help with extra long paper like this that they are running?
Ricoh 9500 Long Drawer Skew Problem
- Thread starter gg2017
- Start date
Paper weight? Is this the top (belt fed) banner attachment, not an enclosed air fed drawer? I have on our 7210 the air fed combo drawer that goes to 27” or so, and it’s not perfect but pretty good using 100# silk cover, certainly close enough for that application (usually large tri folds). I did not choose the belt fed banner attachment because of the paper thickness limitation and the concern about registration.

Is the stock cut straight and SQUARE?
Paper is 100# Silk Text. It is the vacuum fed banner sheet tray that takes the place of a drawer. The paper is cut square. I get some skew on 28" sheets but manageable.

Hi - We had problems with registration that led to your type of issue.
Try turning off the lead edge detector / registration sensor.
The machine MAY be trying to "straighten" it.
This usually worked with longer sheets.
Admittedly then sometimes they moved up or down machine (lead edge difference) but at least they were straight.
But really the registration area is the problem. We did get it working better after the 'tech' began replacing parts.
He didn't bother to determine WHAT part fixed it. Typical.
PS - this didn't start happening until 12+ months after install.
Sigh.
YMMV.

This would be my first guess. If your back gauge is slightly off, or if your cutter operator isn't precisely squaring up the paper, it is exaggerated much more with longer sheets.

We have had a "cutter operate" not know how to square a sheet. Factor paper edges can not be assumed to be square and 1 degree over 8.5 may not be noticeable but 1 degree over 27 or 38 inches will be! Especially when 2 sided changes the lead edge and doubles(reverses) the skew.
That said My ricoh 7210 registers twice as good compared to our canon c750 when running the long sheets same stock same files. Defining the paper correctly is huge. 3 mm is what I see on the canon but a few sheets are exact. If you are seeing a consistent placement then compensate by skewing the image.

Ricoh's registration are FAR superior to Canon, I've got a few dozen. I also have several Ricoh's. Have you registered that paper type? You should be seeing much more than a mm in our experience.

You have a "few dozen" Canon's? Wow, that's an impressive operation! What made your shop buy "several Ricoh's" when you're clearly a fan of Canon? Which models do you have of each brand?

We've most recently run Canon Imagepress's C800, C850, C910. We've had smaller and larger models prior to those as well. Ricoh's, running 9210 and many 9500s.
The Canon C800/850s are pretty good machines for what we need, but registration on anything over a letter is terrible. The 910 took a step backward. In the end, we switched away due to reliability, speed, pricing, and Canon's unwillingness to listen to the customer to fix their problems (including registration).
The 9500's haven't been a cakewalk either, but at least Ricoh is working hard to fix their problems even when Fiery is the source of some of them.

They installed ours so poorly it took us three months to get them leveled and straight.
Because the jams just kept happening. And then voila! all fine.

Try turning off JAM080/097/098/099 on the paper and see if that helps. The issue with the longer paper in the past was when it would shift the paper would not be released all the way back so it would skew.
