Changing the Printer Paper
The roll size is 2-1/4 inches wide by 1-7/8 inch in diameter. Replacement
rolls are available at most office supply stores.
The tester uses only thermal printing paper.
To replace the paper roll:
1. Unlock the printer door by gently pressing forward on the red lever.
Remove the spent roll.
2. Place a new roll of paper in the compartment, and pull the paper for-
ward so that it extends past the serrated edge of the paper slot.
3. Close the door and make sure the lever locks securely.
NOTE: For a clean tear, pull the paper along the edge of the plastic.
Do not pull the paper straight out of the printer.
