	incorrectly	Be sure that ends of the hooks are facing down.
	Defective platen.	To check platen:
		Use an Ohm meter to test resistance of the platen heater
		(disconnect 1 wire to isolate heater). Correct cold resis-
		tance 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 Ohms
		VCT-20 only. The auxiliary heaters are 144.2 Ohms at
		208V/300 Watts.
	Defective or wrong drive	To check drive motor:
	motor.	1.Measure resistance of motor coil. Replace motor if coil
		measures either open circuit or zero resistance.
		2.Mark the drive motor sprocket and count the turns per
		minute. Correct drive motor speed is nine (9) turns per
		minute for VCT-20; three (3) turns per minute for VCT-
		25; one (1) turn per minute for VCT-50.

	Wiring problem.	Check all electrical connections for burns, discoloration
		or arcing. Replace all connections or components with
