Figure 6-4 Changing the Chart Paper
6.4.1 Changing 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.
