To check temperature display control, allow
unit to warm up for 30 minutes, then:
1. Check platen temperature at the center
of platen (with conveyor belt wrap, con-
veyor belt, tensioners and release sheet
removed). Use a pyrometer to confirm
temperature readings.
2. After platen temperature reaches a maxi-
mum of 559°- 561°F (292°- 293°C) and
auxiliary heaters reach a maximum of
339°- 341°F (170°- 172°C), and the tem-
perature begins to drop, the heat indica-
tor light on the temperature control board
should turn on. If test readings do not
agree with these figures, replace temper-
ature display control.
