Label Stock Wrinkles on KMC1060

[OverKnight]

Same machine, different issue... or same issue that is the cause of everything. LOL

In the images I uploaded, there is a defect in the paper created before entering the fuser. Coincidently, I just replaced the fuser belt and the problem became chronic. The stock is 11" x 17", 60lb. gloss label with a 80# liner. Tray 4 is set for 217-256 GSM and this is the primary workload for the machine.

I think it's time for a new secondary transfer roller, but I guessing that the registration roller is pulling too long on the sheet and creating the ripple. Again, the images I uploaded show the image failure on the front (I wiped the toner off that didn't fuse) and the back to show the actual ripple.

Any ideas would be greatly appreciated.

Thanks!

FYI, I just did back of the cover math and 60# + 80# should be 208 GSM? The paper supplier says it is 232 GSM. What say you?

Attached is the Supported Substrate Throughput Assurance Guide for the C1100-C1085-C1070-C1070P-C71hc-C1060-C1060L-C2070-C2070P-C2060 & C2060L. If the media you are trying to run isn't in this guide then its not supported . I know the customer will say that they run this all the time. This doesn't change the fact that its not a supported media.
With that being said it looks like you problem is happing before transfer because there is no image an the wrinkles. Is tray 4 the most straight path on this machine?

OK, I've been in the printing game a long time and having a list of "recommended or confirmed paper stocks" is generally a safe place to start. Printing equipment, even digital presses like these have hundreds of adjustments that compensate for stock grain, temperature, humidity and speed. So the performance of the stock can and will always be the main issue, but not the ultimate answer. If these machines can print on synthetics like polyester and envelopes without question, label stock cannot be that tricky regardless of the brand.

I've made a career out of working with printing machines and ultimately there are always adjustments to be made simply because of bad weather. Another hack that I know about label stock, is chilling. Literally. I put the stock in the refrigerator and lower it's temperature. The tack of the adhesive at room temperature is softer, more pliable. Chilling the stock stiffens it and makes more rigid, thus a temporarily stronger bond. There is a good chance that the 60# Gloss Label is the same grain as the 80# Liner, and that way the two easily wrinkle in line with each other. That being said, there still has to be a setting or adjustment to compensate for that defect.

Thanks for the Guide, it will be helpful in the future!

If there's any doubt about the paper weight ... I weigh it. I have a gram scale. Figure out your area in meters squared. You'll want grams/meters squared.

When you get a wrinkle like that, it's usually caused by uneven pressure or humidity or both. If it's before fusing that pressure will be at the registration rollers. Registration rollers are a consumable part, I believe it's 12M on the 1060, or 1M to 2M if your running NCR stock. The NCR stock causes the rubber to swell at the paper edges causing jamming, skewing, wrinkles, etc. If this is what you're seeing it's not just the registration rollers. Every rubber roller that the paper touches will swell in this same way.

Yes, I believe it happens to coincide with the change of seasons. The higher humidity might be contributing to wrinkling the label stock. The fact it doesn't happen all the time, is normal in the world of printing. The stock is everything, so is the weather.

As for the roller, the manual states the replacement of the registration roller at 1,400,000 prints [Page F-4, Section (14), Number 1, Registration section, Registration roller, A50U7101]. Current count on the roller stands at 1,007,497. That being said, labels are the only product of the machine at 11" x 17".

I will check the roller for inconsistency and try and tweak the settings. Thanks!

I think that answers the question, blackcat4866

I did a test strip method on the roller pressure and the center is loose when supported on both ends with matching strips of 20lb. paper.

Time to order a new registration roller. LOL

Let us know how it goes. Thanks for following up.
