Cleaning the paper roller
Picture postcards and other preprinted media is sometimes dusted with a powder to keep the image on one card from bleeding over to the back of the card stacked on top of it. When feeding such media from the MP tray, the dust tends to get on the paper roller and eventually causes misfeeds to occur. Use the following procedure to clean the paper roller when you start having feed problems from the MP tray.
1.Make sure the printer is turned off.
2.Open the printer cover.
