6.4 Main PCB (PCB1) Calibration Procedure
15. Reconnect the thermal sensor to the Main PCB.
16. Turn Laminator on.
17. Place the beaded thermocouple in the center of the nip rollers (or infrared temperature sensor
pointed right at the nip). Adjust SV2 until the ready light illuminates and the nip temperature is
290°F. Do not let the temperature exceed 310°F (this could cause the rollers to blister).
18. When the unit is heating, monitor the Amp Probe for meter deflection. The Amp Probe should
deflect to indicate that Laminator is heating, and zero out once the unit has gone to ready.
19. The temperature can be fine tuned while the Laminator is hot by adjusting SV2. Turn SV2
clockwise to decrease heat, and counter clockwise to increase heat. Adjust SV2 in small
increments, and then wait at least 5 minutes for the heat to stabilize. Check temperature with
infrared temperature sensor or beaded thermocouple.
20. Your Main PCB is now calibrated. Remove Amp Probe, and replace left side cover.
