There is a usb power plug in back and removable back for paper jams.

It gives me a hard time often when it stops printing because there is an inexistent paper jam.

After three paper jams I finally gave in and watched the video

Once I got that worked out, I tried to print and the paper jammed

I've had (2) paper jams in the (2) months I have owned it

Worst purchase I have ever made, paper jams constantly from either feeder, hard to program with the touchscreen..doesn't recognize commands.

The other is with the bottom paper tray which is a bit touchy and if not perfect will lead to paper jams.

I had purchased Canon products (camera and printers) and for most part they work as per the specs, though the user interface is not exactly friendly

Very nice e to have
