We have a GBC Ultima 65 laminator. It has stopped running. Any ideas for where to start looking? Cecked the circuit.

At those prices they should come out and fix it for free. It sounds like the motor has failed or or is cutting out on an overheat thermal limiter. Reach out ot them for support.

First guesses are

1. Paper is damp?
2. Heating element is failing?
3. Speed of travel is set too fast?

That is a general problem with small synchronous motors, they can run either way. If they start backwards, they are supposed to reverse themselves. Usually, removing the plug and plugging it back in will correct. Eventually, you will need a new motor unit.

you may try using tweezzer or use compressed air to dislodge it

Most likely cause is from the heat rollers having deposits of sticky junk on them. i found a video on cleaning them and will be below.

sounds like the yellow and the orange wire connectors on the main board from the transformer are reversed. If not, then your main board needs replaced. I have them available, 405-324-6092, Scott,

Ordinarily, laminators have speed controls to allow the laminated substrate to get hotter.

either the top heater tube, (inside the orange/red roller) is burned out (Open) or the wire on either side of the heater tube is burned or broken in half. It\'s not as bad as you might think.

Could have a bad heat lamp, do your adhesive feel tacky on any of the rollers? Are you may have a bad triac

So this is how you remove the fuse that's underneath the machine, under the power button? Thanks!!
