I have been dealing with a roller mark issue and the Epson 3880 for some time. It involves an exotic material that is not relevant to this discussion and I was searching the internet for the "roller mark" topic to see if I could dig up any additional indicators, when I found this thread.
It was in reading this thread that I learned there was a more or less universal roller mark problem with less exotic materials and occurring across printer brands, as referenced by several persons, here. Until now, I thought a roller mark issue with HP brand printers that I solved several years ago was unique to that brand and that what I was experiencing with the 3880 and the aforementioned exotic material, was a one-off thing of no interest to anyone but me.
I have the answer, at least for one printer brand and it is most likely an indicator for the other two. First, a little history.
I had an HP B9180 (and its eight replacements under warranty in less than three years) that was producing roller marks on prints made on a variety of matte, inkjet coated papers, primarily in the heaviest blacks. It was not occasional and quite ruinous. (And BTW, some here mentioned they thought the problem was not common. Yes, it is. The problem is that most people don't examine prints very closely and miss the roller marks. I have said "yes it does" while at the same moment pointing roller marks out to people on their very own HP prints, before they actually saw them.)
With HP printers these marks tend to show in the darkest areas where ink deposit is heaviest. HP knows about the problem, but they won't admit it exists. They count instead on the the lack of observation on the part of most of their users. They of course said the problem must be with the brands of paper that were not their own. (Sound familiar?)
With HP printers, the roller marks are the result of heavy ink deposits having insufficient time to dry before being run over by rollers in the machine. After I realized this, the solution was simple and is 100% effective:
During the entire printing process, stand in front of the stupid printer with a handheld hair dryer and blow warm air into the printing path, moving the hair dryer back and forth, across the printer. No roller marks, ever again. Of course, the printer I had did not offer a more reasonable solution: increase the drying time between passes. If your printer has that option, try it first.
Now the Canon printers. I have never owned a Canon printer and have no clue. Try the two options above first, before moving on to the Epson options.
Roller marks with Epson printers ARE NOT the result of rollers marching through still-wet ink as they are with HP. At least not with the material that has been driving me nuts and therefore, probably not with your materials, either. AND, Epson printers are designed differently. There aren't any rollers to pass through after ink has been deposited. At least not in the 3800/3880/P600 series.
I ran tests with only two thin lines of black ink down the edges of the print area, parallel to the paper path and at the outside edges of the image area. Roller marks occurred on the material, in between the lines, where no image at all was printed. So, if you are going to get roller marks on the material you are using, it will happen even if you print no image at all. However, ink deposit does of course make the marks far more noticeable.
With the Epson printers, try the hair dryer trick and try increasing the drying time between passes, if your printer has that option. Someone mentioned somewhere in this thread that increasing drying time did have a positive effect.
Recent communication with another researcher using the same exotic material I mentioned originally suggests strongly that this problem, at least with Epson brand printers, is related to relative humidity. I live in dry Arizona, he lives in the NorthWest where he practically needs SCUBA gear 24/7. His roller marks are infinitely worse than mine.
Put a dehumidifier in your work area if you can, AND take a hair drier to your paper BEFORE you print on it. And brush it off first, too. Paper debris doesn't help this problem.
As I understand it now, all three printer manufacturers have this problem and all three refuse to acknowledge it, so the only thing that will get them off the dime is a lot of complaining. Most people using these printers do not see the roller marks on their prints. Point them out to them.
