i have the tray in the correct position and push the little green button when it comes on to insert paper but then the yellow light blinks and won't take the paper.  Please help.

Hi kcp,

Do you happen to notice a pattern to the blinking lights?  Maybe a series of flashes and then a pause?  How many flashes between each pause?  This information could point to specific error that we can troubleshooting.  Also, since I'm asking questions: What operating system are you using?
