The Solid State Relay is defective (it has a permanent ‘open’ state; in this case, the red LED on
the Solid State Relay is constantly on).
Solution:
Replace the Solid State Relay, see Section 4-1.
The overtemperature switch is defective (it has a permanent ‘open’ state; in this case, the line
voltage can be measured between it’s connectors).
Solution:
Replace the overtemperature switch. See Section 8-3-2, Assembly Drawings
& Exploded Views, drawing no. 144-185 / 144-187, art. code 961-6003.
The Control PCB is defective (if the previous checks are OK).
Solution:
Replace the Control PCB.
Problem:
The temperature-ready LED starts flashing at a fast rate after some 20 minutes, and continues to do
so. The top cover is warmer than usual.
Cause:
The Solid State Relay is defective.
Solution:
Replace the Solid State Relay, see Section 4-1.
Problem:
Pouchboards are not drawn in by the machine, and the motor is making a louder humming noise (it’s
stalling). Only after pushing very hard, the boards are accepted.
Causes:
The Pouchboard is too thick for the chosen nipsetting.
Solution:
Check the nipsetting that corresponds to the boards used.
Boards of another make are used.
Solution:
Use only ProSeal Pouchboards.
The nip adjustment is not correct.
Solution:
Perform the Nip Adjustment procedure (see Section 3-2).
Problem:
The quality of the lamination is poor: silvery areas on dark surfaces are visible, or the edges of the
image are not sealed well.
Causes:
The roller temperature is too low.
Solution:
Perform the Temperature Adjustment procedure (see Section 3-3).
The roller pressure is too low.
Solution:
Perform the Laminating Pressure Adjustment procedure (see Section 3-1).
Problem:
The quality of the lamination is poor: especially laminated inkjet prints show bubbles.
Cause:
The roller temperature is too high.
Solution:
Perform the Temperature Adjustment procedure (see Section 3-3).
