NOTES:
1. When the power sup ply v ol tag e drops to the low er l im it, the printer stops printing and
then starts printing on that line again more slowly than before.
2. When the head temperature rises to the upper limit, the printer stops printing. When
the head temperature falls to the normal level, the printer start printing again more
slowly than before.
3. Copy 1: When the paper thieckess lever is set to 2 or 3.
