Precautions for the use of coffee printers mainly include the following aspects to ensure the normal operation of the equipment, extend the service life and ensure the safety of users:

First, the preparation before the operation

1. Ingredients: Make sure to use quality coffee beans and grind them into a fine powder, and prepare optional ingredients such as milk or plant-based milk (if you need to make milky coffee such as lattes), latte chocolate powder or cinnamon powder.

2. Equipment inspection: Check whether the water tank of the coffee printer is filled with fresh cold water to the "MAX" mark line, and confirm that the coffee powder silo, steam rod and other parts are clean and free of blockage.

Second, precautions in the operation process

1. Safe operation:

- Avoid touching hot parts such as steam rods and hot water outlets during operation to prevent burns.

- Ensure that power outlets are well grounded and avoid using extension cords or multifunction outlets to reduce safety hazards.

2. Set the parameters correctly:

- Set extraction parameters, including extraction time, pressure and temperature, according to the type of coffee beans and personal preferences.

- When printing coffee images, use distilled or purified water to prevent impurities from clogging the nozzle.

3. Stable placement:

- Place the coffee printer on a level, stable table or countertop to avoid tipping.

- Make sure there is enough space around the printer for heat dissipation and operation.

Third, maintenance and maintenance after use

1. Timely cleaning:

- After each use, clean coffee powder silos, steam rods and other cleanable parts in time to prevent blockage and odor caused by coffee grounds and milk residue.

- Use a soft dry cloth to wipe excess water from the surface and inside of the machine and keep it dry.

2. Regular maintenance:

- Regularly check whether the filter screen, steam pipe and other parts of the printer are blocked or aged, and clean or replace them if necessary.

- Clean the printer's print head and cartridge regularly to ensure print quality.

3. Storage and maintenance:

- If you do not use the coffee printer for a long time, turn off the power and place the machine in a dry, ventilated environment.

- Avoid placing the printer in direct sunlight or wet places to prevent damage to the machine.

Fourth, other precautions

1. Avoid overload use: When the printing volume is too large, there should be free time for the printer to rest, so as to avoid overheating and damage.

2. Software and drivers: Make sure dedicated applications or drivers for your coffee printer are kept up to date for optimal performance and compatibility.

3. Professional maintenance: in case of problems such as printer failure or performance decline, professional maintenance personnel should be contacted in time for inspection and maintenance, do not disassemble or repair yourself to avoid greater damage.

In summary, by following the above precautions, you can ensure the normal operation of the coffee printer, extend the service life and ensure the safety of the user.
