5. Operating Instructions
This section details the steps for operating your BUUBO F320 Mug Heat Press Machine.
5.1 Powering On and Off
- To power on, press the power button located on the control panel. The display will illuminate.
- To power off, press and hold the power button until the display turns off.
5.2 Setting Temperature and Time

Figure 3: The innovative knob control panel allows for easy adjustment of temperature and time settings. Turn right to set temperature, turn left to set time.
- Temperature Setting: Turn the control knob to the right. The temperature value on the LCD display will flash. Rotate the knob to adjust the desired temperature (e.g., 380°F / 193°C). Press the knob once to confirm.
- Time Setting: Turn the control knob to the left. The time value on the LCD display will flash. Rotate the knob to adjust the desired time (e.g., 180 seconds). Press the knob once to confirm.
- The machine will begin heating to the set temperature. An audible alarm will sound upon reaching the target temperature.
5.3 Preparing the Mug/Tumbler

Figure 4: This image illustrates the various cup types and sizes compatible with the heat press, including tumblers, can coolers, glasses, sippy cups, and mugs, along with maximum height and diameter specifications.
- Ensure the mug or tumbler is clean and dry.
- Print your design onto sublimation paper using sublimation ink.
- Securely attach the sublimation paper to the mug/tumbler using heat-resistant tape, ensuring the design is flat against the surface.
5.4 Sublimation Process

Figure 5: This diagram highlights the 620W high-power heating element and the anti-scalding Teflon coating with a thermal silica-gel inner layer, ensuring efficient and uniform heat transfer for quick sublimation.
- Once the machine reaches the set temperature, carefully open the press.
- Place the prepared mug/tumbler into the heating element. Ensure it is centered and the pressure is evenly applied.
- Close the press handle firmly. The timer will automatically start counting down.
- When the timer reaches zero, an alarm will sound. Carefully open the press handle.
- Wearing heat-resistant gloves, remove the hot mug/tumbler and place it on a heat-resistant surface to cool.
- Once cooled, carefully remove the sublimation paper to reveal the transferred design.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your heat press.
- Cleaning: After each use, ensure the machine is unplugged and cooled. Wipe down the heating element and exterior surfaces with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the machine in a clean, dry, and dust-free environment when not in use.
