Product Overview

Setup

- Plug the power cord into a standard electrical outlet.
- Turn on the laminator using the power switch. The indicator light will illuminate.
Operating Instructions
1. Warm-up
After turning on the laminator, it will begin to warm up. This typically takes less than 5 minutes. The indicator light will turn green when the laminator is ready for use.

2. Preparing the Document and Pouch
Place your document or photo inside a laminating pouch of the appropriate size (A4, A5, or A6). Ensure the document is centered and leaves an even border on all sides for optimal sealing.
3. Laminating Process
- Once the green indicator light is solid, carefully insert the sealed edge of the laminating pouch into the feed slot of the laminator.
- Keep the pouch straight and centered as it feeds into the machine. The laminator will automatically pull the pouch through.
- Do not pull or push the pouch during the lamination process.
- The laminated document will exit from the rear slot. Allow it to cool on a flat surface before handling.

4. ABS Function (Jam Release)
If a pouch becomes jammed or misaligned during lamination:
- Immediately turn off the laminator.
- Press and hold the ABS button. This will release the pressure on the rollers.
- Gently pull the jammed pouch out of the feed slot.
- Once the pouch is removed, release the ABS button.
- Allow the laminator to cool down before attempting to laminate again.

Maintenance
- Cleaning: Ensure the laminator is unplugged and completely cool before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Roller Cleaning: Periodically run a cleaning sheet (available separately) through the laminator to remove any adhesive residue from the rollers.
- Storage: Store the laminator in a dry, dust-free environment when not in use.
