 Note: (1) If printed results are uneven, light or splotchy try increasing HEAT or reducing PRINT SPEED as
no further adjustments may be needed; (2) during the procedure below, synthetic media may not
produce the intended results due to the requirements of the material; and, (3) in extreme
conditions, over-temperature protection circuitry can interrupt printing.
