[QUOTE=motifone;2174510]Thanks for the input. The rubber rollers are definitely the culprit, and this seems to be how the printer is designed. Apparently, the R280 (and possibly other Epson models) has rubber rollers that contact the unprinted surface of the DVD and push it along (see linked picture below. The tooth feeders never touch the disk, just the rollers, which result in one long continuous mark (like someone ran over it with a mini-tire)
It’s noticeable when viewing the disk at an angle, and is probably more prominent because I have a dark background. I’ll try a new design or if it bugs me I’ll have to use their matte media.
Link to R280 rollers:
FYI That’s not a Taiyo disk in the image above, just a sample disk for testing[/QUOTE]
It’s been a while since my R280 hit the dumpster, but I don’t recall it ever doing that. If it did, it was very faint. It might also fade over time as the coating dries out. I do know that the Canon only has rollers touching the edges of the tray, not the disc. I remembered that the Epson was the same way, but my memory isn’t what it used to be.
But those rollers don’t push or pull, they just hold it down. As I recall, when the tray is inserted, it flips a lever that lifts the toothy feed rollers and also drops a set of edge rollers onto the tray. (you feel the resistance when inserting the tray) In the Canon, this happens when the door is opened.
Verbatim Gloss is a good alternative, it’s a lot less glossy. But not hub-printable.
