Printing Parameters Reference
The following table provides recommended settings. Adjustments may be necessary based on material and transfer thickness. Always test with a sample first.
| Material | Machine Status | Temperature | Time |
|---|---|---|---|
| Stainless Steel Tumbler | Hot (>140°F) | 356°F - 365°F | 60s + 60s / 90s + 40s |
| Glass Tumbler | Hot (>140°F) | 356°F - 392°F | 60s + 60s / 120s + 120s |
| Porcelain Mug | Hot (>140°F) | 374°F - 392°F | 200s - 300s |
Pressure Value Reference (DN)
| DN | Diameter Range |
|---|---|
| 75 | 2.75" - 2.83" |
| 65 | 2.87" - 2.91" |
| 55 | 2.91" - 2.95" |
| 40 | 3.07" - 3.14" |
| 15 | 3.26" - 3.3" |
| 8 | 3.34" - 3.38" |
Note: As the material and thickness of the transfer are different, the set temperature and time should also be different. Please take a sample to test for a great temperature, time, and pressure first to avoid mistakes and loss in subsequent mass production.
Maintenance
- Cleaning: Ensure the machine is unplugged and cooled before cleaning. Wipe down the exterior with a soft, damp cloth.
- Fuse Replacement: If the machine loses power, check the fuse located on the side panel. Replace with one of the provided spare fuses if necessary.
- Heating Element: The heating element is designed for durability with 3 layers of thickened silicone protection. If replacement is ever needed, consult EENOUR customer support.
Troubleshooting
- Uneven Press/Ghosting: Ensure the pressure setting is appropriate for the diameter of your item. The machine supports pressure value settings for cups in the diameter range of 2.75-3.45 inches. A stable and suitable pressure is crucial for even sublimation results.
- Machine Not Heating: Check the power connection and the fuse. If the fuse is blown, replace it.
- Paper Not Tight Enough: Ensure the sublimation paper is tightly wrapped around the tumbler/mug and secured with heat tape to prevent gaps or shifting during pressing.
