	Platen inoperative.	To check platen:
		Use an Ohm meter to test resistance of the platen
		heater (disconnect 1 wire to isolate heater). Correct
		cold resistance for heating element of platen are as
		follows:
		120 Volts, 1750 Watts - 7.8 Ohms
		208 Volts, 2550 Watts - 16.2 Ohms
		230 Volts, 1900 Watts - 26.5 OhmsVCT-20 only. The
		auxiliary heaters are 144.2 Ohms at 208V/300 Watts.
