6.4.1Changing the Roll of Paper

To change the chart paper you will need:

•a new roll of paper

•a knife or a pair of scissors

•a small piece of tape

The printer will shut down when the paper runs out. The roll is nearly empty when a 1-inch wide pink band appears on the left side of the chart.

To remove the used roll:

1.Locate the handle on the left side of the take-up roll.

2.Pull straight out on this handle until the take-up roll slips off the printer.

3.Remove the paper roll from the take-up spool by holding the handle in one hand with your thumb pressed against one of the slots in the white end cap.

4.Snap the white end cap free from the two black catches on the end of the spool.

5.Pull the paper roll off the spool with your other hand.
