Remove the paper tray(s) from the printer and place near the edge of the work surface to allow easy access to the underside of the paper tray bay.  Locate the feed roller then remove it  by pinching the blue lock tab on the roller, then sliding the roller off the left end of the shaft.

Please Note:
If you purchased the optional paper pickup roller, this is the easiest time to install it. The paper pickup roller is not included in the maintenance kit; however, to keep your printer working at its best, it is highly recommended to replace it on the same schedule.
