I believe that many sublimation lovers who have printed skinny tumblers with full images often have the problem that there is always a seam where the images meet. It’s hard for us to print a perfect tumbler with seamless, but we can minimize your seam on the final result, below are some tips that may be helpful for you.

Tools that may be helpful to you:

Heat-resistant tape, paper trimmer, lint roller, scraper.

1. Cut the right size sublimation transfer paper.

Trim the image with the paper trimmer, and trim as close as you can to your edges. Make sure to trim off all white margins.

2. Wipe the tumbler with a clean rag or a lint roller, and make sure the surface has no flaws and blemishes.
3. Stand your tumbler upside down on the table and put your pattern around the tumbler and level-squeeze it tightly.
4. Pull it tight and get the seams close to each other, and fix a long piece of tape on the seam from bottom to top. The top and bottom of the tumbler should also be fixed with heat-resistant tape.
5. Go run the scraper right down the seam, and make sure no air on the seam line.
6. Setting appropriate parameters for your tumbler heat press and put it in the machine, start printing. If you’re going print the skinny tumbler with a sublimation oven, you have to use a blower gun to wrap the skinny tumbler with a right-size shrink film.

Press the “CLEAR” button once to start countdown, and press it once again to stop. Or you can replace the door magnetic valve.

Check if the fuse is broken or burnt. If so, please replace it. The machine comes with one spare fuse.

1. Check the heating attachment first. If you have a spare heating attachment, install it on the machine and check if it can heat up normally. If the spare heating attachment works well, it means the old heating attachment is broken.Check the heating attachment first.

2. If neither the old heating attachment nor the spare heating attachment heats up properly, maybe the mainboard is the cause.

Check if the plug is connected properly and fastened. If the heating attachment still doesn’t heat up, please contact our sales representatives to order a new heating attachment.
