Can't get yellow light to stop blinking nor find any jam.

Can't get yellow light to stop blinking nor find any jam.

My PIXMA MG 3022 printer has yellow light flashing and I do not see any paper jam. This is my second printer that this happened. The last time I used this printer, it did not jam, nor did I turn it off w/jam. Can you help me with this problem. The printer does great quality work and is convenient to use. THANKS
