Inspect a laminator roller for damage if you begin seeing wrinkles on the film that extend from one side to the other. Additionally, blisters, impressions, spots and bubbles are signs that rollers may need to be cleaned or replaced. Sticky film can adhere to the heat shoes and make it harder to handle. If the roller does not pull the film, the roller pressure may also need to be modified. Cleaning the rollers and adjusting the pressure are two good places to start your strategic repairs.
Turn off the laminator and unplug it.
Take off both the left and right housings.
Wipe the rollers. Use a clean, soft cloth dipped in either a cleaning solution provided in a cleaning kit or isopropyl alcohol.
Adjust the pressure. Raise the pressure adjustment screws to increase the roller pressure; lower them to decrease it. Raise or lower the pressure adjustment screws evenly on both sides. Only make an adjustment to one side if you are evening up the pressure on one side to match the other side.
Tighten any loose pulley screws. If the rollers and motor do not turn properly, take off the side panel to access to the base of the pulley where the screws are located.
Plug the machine back in and turn it on.
Wrinkles on the laminating film from one side to the other are an indication of dirty, worn out or damaged rollers. Try to clean the roller first to avoid an unnecessarily early replacement.
Take precautions, adhere to safety policies and practice personal safety. Wear appropriate safety glasses before you attempting these steps.
