The following matters need to be noted when cleaning the printer nozzle:

I. Preparation

1. Choose appropriate cleaning tools and materials:

• Use special nozzle cleaning fluid, and avoid using inferior or incompatible cleaning fluid to avoid damage to the nozzle.

• Prepare clean cotton swabs, soft cloth or dust-free paper towels, etc., to wipe the nozzle.

2. Make sure the printer is in a safe state:

• Before cleaning, turn off the printer power and unplug the power cord to prevent electric shock or accidental startup of the printer.

II. Cleaning process

1. Gentle operation:

• Whether soaking or wiping the nozzle with cleaning fluid, the action should be gentle to avoid excessive force to damage the nozzle.

• When using tools such as cotton swabs, do not let their fibers remain on the nozzle.

2. Prevent liquid from entering the inside of the printer:

• During the cleaning process, be careful to avoid the cleaning fluid from flowing into the circuit or mechanical parts inside the printer to avoid damage to the printer.

3. Clean in the correct way:

• If you use software to clean, follow the steps in the printer manual.

• For immersion cleaning, control the immersion time and the concentration of the cleaning solution.

III. Post-cleaning treatment

1. Drying treatment:

• After cleaning the nozzle, use a clean soft cloth or paper towel to gently wipe the moisture or cleaning solution on the surface of the nozzle, and ensure that the nozzle is completely dry before installing it back into the printer.

2. Test printing:

• After installing the nozzle, perform a test print to check whether the nozzle is clean and whether the print quality has returned to normal. If there is still a problem, you can repeat the cleaning steps or seek help from a professional maintenance person.
