What should I do if there is a paper jam inside the ET-2803?

Paper jam solutions are covered in the Paper Jam Problems Inside the Product section under Solving Paper Problems. You should follow the step-by-step instructions in that section to safely remove jammed paper without damaging the product. Do not use wavy, torn, folded, damp, too thick, too thin, or curled paper, as these types can cause paper jams. (Page 203)
