REASON

1. Ink cartridge or ink system issues:

• Overfilling or improper filling of ink:

If ink has been replaced or replenished recently, it may cause internal pressure imbalance due to excessive injection or improper operation, and ink may seep out from the nozzle.

• Ink cartridge damage or poor sealing:

Ink cartridge leakage, aging or damaged sealing ring can cause ink leakage. Check if the ink cartridge has cracks or loose interfaces.

• Non original/inferior ink:

Compatible ink may have mismatched viscosity (too thin) or contain impurities, resulting in excessive fluidity and dripping.

2. Print head problems:

• Blocked or dirty nozzles:

Partial nozzle blockage can cause ink to accumulate in the nozzle and eventually overflow from other locations. Try using the printer's built-in "clean nozzle" function for processing.

• Nozzle aging or physical damage:

Long term use or improper cleaning may cause nozzle deformation or breakage, and replacement is necessary.

3. Mechanical or structural failure:

• Saturation of waste ink pad:

The sponge pad inside the printer that absorbs waste ink is already full (common after long-term use), and it is necessary to contact after-sales service for cleaning or replacement.

• Printer tilt or vibration:

The machine is not placed horizontally or is subject to shaking during printing, which may cause abnormal ink flow.

• Ink supply system malfunction:

The pipeline pressure imbalance, air leakage, or high/low position of the continuous ink supply system (continuous supply) may cause ink dripping.

4. Environmental factors:

• Temperature changes:

High temperature environments can cause ink to expand, while low temperatures may lead to sudden release after condensation, both of which may cause leaks.

• Paper or medium mismatch:

Using paper that is too thin or has poor ink absorption, ink cannot be quickly absorbed and accumulates on the surface.

5. Operation or setting issues:

• Setting the print quality too high:

When selecting the "High Quality" mode, the inkjet volume increases, and if the paper does not match, it may cause ink accumulation.

• Long term disuse:

The ink suddenly starts up after drying up at the nozzle, which may cause brief drops of ink due to pressure changes.

SOLUTION STEP

1. Immediately stop printing, remove the ink cartridge to check for leaks, and clean the surface of residual ink.

2. Run the printer's built-in nozzle cleaning program (1-2 times to avoid excessive ink consumption).

3. Check the continuous supply system (if any): Ensure that there are no creases in the pipeline and that the ink tank is level with the printer.

4. Replace the original ink cartridge/ink to eliminate compatibility issues.

5. Check the waste ink pad: If the printer prompts "waste ink pad is full" or there is ink leakage at the bottom, professional maintenance is required.

6. Adjust the environment: Keep the printer horizontally placed to avoid extreme temperatures.

If the above steps are ineffective, it may be due to internal component failures (such as print heads or motherboards). It is recommended to contact the manufacturer's after-sales service or professional repair personnel.
