Out of paper

If the printer is out of paper then the light will let you know by turning red.

  2. Click the Tools tab
  3. Expand the Tools option and click the Tools… option above Status Polling

Paper won’t feed

Printer is out of paper

First double check the printer still has paper. If it does, make sure it is securely sitting in the holder.

The top lid is open

Make sure the top is securely latched shut. It takes a good push for it to lock.

Feed button is defective

If you are trying to feed with the feed button, it may be that the button is defective and needs to be replaced. See this guide on completing this repair.

Paper feeder needs replacing

It is possible that something is stopping the paper feeding roller to not move properly. One of the feeding rollers or a motor may need to be replaced.
