Its malfunction of sheet path paper sensor due to dust, don't open any thing just high pressure air pump required(ex bicycle pump)blow on sheet paper path sensor located just left above of paper roll path(look black "U" shaped, blow air in it.. check it will get resolved... Reason:the IR paper sensor shell having very small path(holes both side) to run the IR beam to other side, if the dust accumulate on IR diode the rays unable to travel to other side, result malfunction of sensor, if we blow presser air on it, dust will clean & sensor will work normally.. Its not funny remedy..it will work try it...
