Strongly suggest you get some rubbing alcohol and a cotton swab. Remove paper tray. Dip swab in alcohol , and clean the paper pickup roller. Don’t touch pickup roller(s) with your bare fingers. Oils can get on roller. Don’t ever turn printer upside down! Use good/fresh/flat paper. Leaving paper in the tray for extended period of time can cause paper to curl on the ends.
2 big reasons is loose belt that will slip & will not get into full spin AND the number one reason is defective lid switch! Wire falls off or switch fails then it will not go into spin cycle (thinking the lid is open).
Follow the instructions to sync. I have had my Propel HD Drone for three months nd it's still going strong! I did clip house that broke one of the support arms. I ended up purchasing two plastic bodies from Propel for whopping $3.50 each! Believe me when I say it was real P.I.T.A. to swap the motors/board/camera! For starters their are 32 micro screws! 7 on each arm and 4 on the body! My biggest problem was the routeing of the wires to the plug that plugs into the camera! The wire is "threaded" thru couple holes in the lower half of the shell. Had to de-solder/re-solder 4 very small wires! I had the experience and the proper sized soldering gun. Price Update From above; "absolutely no service. $200 for the drone and $60 for the new body and no response to emails from the company." $200 for the drone? Mine cost me $80.00 new. $60 for "new body" , really? Currently $4.99 on the Propel web site. I realize the prices are high when first manufactured . Just go to the company web site to get current...
