I. Regular Inspection and Maintenance of Inkjet Coding Machines
Check the liquid levels of ink and solvent daily. Monitor the ink level and solvent level; if the level is too low, add the corresponding material in a timely manner in accordance with the procedures. Do not overfill the ink bottle when adding ink-overfilling may cause ink sedimentation, which not only wastes consumables but also affects printing quality.
Verify the normalcy of ink viscosity daily. Ink viscosity is crucial for the stable operation of the inkjet coding machine:
If the ink viscosity is too high, it may increase the load on the main pump, leading to damage to the motor diaphragm.
If the ink viscosity is too low, it may cause the pressure pump to run at high speed; prolonged high-speed operation will shorten the pump's service life.
In addition, a significant deviation between the actual ink viscosity and the set value will also affect the printing quality of products. Therefore, it is essential to ensure the ink viscosity remains normal.
Clean and dry the print head before use every day. The print head is a key component of the inkjet coding machine. If the print head is too dirty, it may cause abnormal ink charging and large voltage fluctuations at the deflection plate, which directly impairs printing quality. If the print head is found to be dirty, clean it promptly and dry it with a hair dryer after cleaning.
Clean the area around the inkjet coding machine daily, especially the hygiene of the machine's outer casing. Keep the casing clean and free of ink stains-this prevents ink from dripping onto the casing and causing corrosion, and properly maintaining the outer casing effectively extends the machine's service life. Dispose of used solvent bottles, cleaning rags, and paper scraps.
Clean the filter screens and inspect the fans weekly to prevent dust from entering the circuit system. Regularly cleaning the air filter screen ensures smooth air circulation, keeping the circuit system at room temperature. Fans are also essential for maintaining a normal temperature inside the electronic system cabinet.
Replace the main filter of the inkjet coding machine regularly-this is a key maintenance task. Sedimentation of ink impurities can easily cause unstable operation of the machine; more importantly, a clogged filter will seriously affect the service life of the pressure pump. Regular filter replacement will significantly extend the pressure pump's lifespan.
II. Long-Term Shutdown of Inkjet Coding Machines
If the machine is shut down for more than three days before being restarted, the nozzle will usually be clogged (this is especially true for anti-migration black ink machines). In such cases, remove the nozzle and clean it thoroughly.
During long holidays (e.g., the Spring Festival), drain the ink from the inkjet coding machine and fill it with solvent for maintenance. This is particularly important for white ink machines-prolonged inactivity can cause ink sedimentation, which severely damages the machine.
III. Handling and Placement of Inkjet Coding Machines
In principle, only one inkjet coding machine can be placed on each production line. If production needs require it, an additional machine with a different ink color may be placed. It is strictly forbidden to place more than two machines on a single line.
If the inkjet coding machine malfunctions, resolve the issue immediately and contact maintenance personnel. Do not randomly move machines from other production lines; if movement is absolutely necessary, obtain approval from maintenance personnel first. If a malfunction occurs at night when no maintenance staff is on duty, move the faulty machine to the maintenance room with a note explaining the issue. It is strictly forbidden to pile up faulty inkjet coding machines on-site.
When handling the inkjet coding machine, handle it with care to avoid excessive vibration. Rough handling is strictly prohibited, as it may cause damage to the machine.
IV. Use and Storage of Inkjet Coding Machine Consumables
The consumables used in inkjet coding machines are highly volatile. When storing them:
Keep the temperature below 35°C to avoid exposure to high temperatures.
Keep them away from fire sources and heat sources.
Ensure they are well-sealed and store them in a well-ventilated area (e.g., inside a thick-walled iron cabinet with good airtightness).
Use consumables that strictly match the brand and model of the inkjet coding machine. Do not use substitutes, as this may cause severe damage to the equipment.
If solvent is splashed into the eyes, immediately rinse the eyes with plenty of clean water.
V. Regular Training
Conduct regular training and assessments for operators (the manufacturer provides free return visits every month-you can request training from the manufacturer). Only by continuously improving operating skills can the machine operate at its optimal performance, reduce unnecessary waste, and minimize product defects.
Every inkjet coding machine has a fixed service life. During daily use, handle the machine carefully, pay attention to details, conduct regular inspections, and prioritize maintenance.
