and perform the following steps and repeat the test after each one:
1. Lift the Media Lever and insert thick media into the paper path to
push out any media that may be stuck there.
2. Open the Window and check for any visible obstacles restricting the
movement of the Drive Roller. If there is a wrinkled mass of media

and clear the obstruction. If you cannot reach the media, remove the
Entry Roller ⇒ Page 8-106 to gain better access.
3. Remove the Paper-Axis Motor (⇒ Page 8-100) and check the Drive
Roller movement is smooth and if it is not, remove the Center
Platen (⇒ Page 8-112) to check for any obstructions.
