Epson stylus photo R300 cd/dvd tray not set correctly

I had the same problem. Restarted the printer. Reinstalled the drivers. Scratched my head ... nothing! then I moved the printer away from the wall - problem solved! I can't say that this will work for you but if everything else is working, as it was and still is on mine then it's worth a try.
What I didn't realsie was that the cd tray comes out of the back of the printer when it's checking the alignment. I had inadvertantly pushed the printer back, too close to the wall. Moved it forward slightly and it's fixed.
Hope that solves it for everyone.

I have had this problem when using the guide arrow on tray to line it up.When I push the tray in farther about a half inch it seems to work fine.

You can try and reset the printer with software let me no if you dont haver it

Ok, I have finally found the solution that works for me *every time.* When you send the file to the printer, the ink / print head carriage will travel from its rest position on the right, all the way to the left, then back to the right.

As soon as that carriage has returned to the right, (that's when the printer motor begins feeding the CD tray) you gently put your finger on the end of the CD tray, and give it a gentle push for 5-6 seconds to help the printer feed motor. This works every time; and when I fail to do this, I get the error message every time. I've tested this successfully, printing almost 100 CDs.

I was having similar problems. I cleaned the white strip on the tray, removed the back and leaned down on the top of the printer itself. That seemed to do the job. It is making strange sounds though.....SIGH.

I found to position the dvd printer tray slightly higher helps. I put a small box underneath the add on feeder thingy and that seems to increase my probability of it working. Other than that my next printer will not be an epson. This is now my second epson printer that has feed problems with dvd printing. Try five times for one time that works.
