C6280 won't feed paper -- sees paper trays as empty

[jmcct]

Can't say that I'm pleased with this printer. It worked well enough until the yellow ink cartridge jammed (printing fewer than a dozen 4x6 images and a couple dozen sheets of paper with smaller images). Couldn't get a single replacement cartridge so I bought a full set. Wouldn't be so bad, except that once the ink was replaced, something else happened to the feed mechanism and no matter how much paper is in either of the feed trays the "Out of paper" message appears on the pop-up screen.

What I've tried so far: unplugging and decabling the whole thing; printing from the card reader so the computer's not involved; removing the back and cleaning the rollers (which seem to  be pretty dry/slick?)

Thanks for your help.

This video should help.

I have the same problem and the solutions video has not helped.  I've been able to print using the fast/economical print setting.  This seems to quickly feed the paper into the reel and the printer continues the job, rather than the slower normal mode where the printer hangs up and the Out of Paper error message appears.

ANy suggestions?
