Правилно одржавање и рад је пресудно за спречавање зачепљења у ДТФ-у (Директно на филм) штампари. Below are some effective strategies focusing on ink quality, printing operations, routine maintenance, and environmental conditions.
Ink Management
1. Choose High-Quality Ink:
• Always use original manufacturer ink or compatible high-quality ink. These options are less likely to contain impurities, have better fluidity, and reduce the risk of sedimentation and drying.
2. Proper Ink Usage and Storage:
• Shake the ink thoroughly before use to ensure uniform composition.
• Seal the ink tightly after printing to prevent evaporation and drying.
• Store ink according to its recommended conditions and avoid using expired or deteriorated ink.
Printing Operations
1. Maintain Regular Printing Frequency:
• Avoid leaving the printer idle for long periods. Conduct 1-2 test prints weekly to keep ink flowing through the printhead and prevent it from drying.
2. Optimize Printing Tasks:
• Reduce frequent short print jobs, as these cause the printhead to start and stop often.
• Add colored stripes or patterns at the edge of your prints to ensure all nozzles are actively used, preventing clogging in less-used nozzles.
3. Proper Shutdown Procedures:
• After printing, allow the printhead to return to the capping station or ink stack to stay in a moist environment before powering off the printer.
Routine Maintenance
1. Clean the Printhead Regularly:
• Depending on usage frequency, clean the printhead weekly or biweekly using a cleaning solution and a lint-free cloth or cotton swabs. Remove any ink residue or debris gently.
2. Inspect Ink Cartridges and Ink System:
• Check ink levels regularly and replace low or empty cartridges promptly.
• Inspect ink tubes and dampers for damage, leaks, clogs, or deformation, and replace if necessary.
3. Keep the Printer Interior Clean:
• Use a vacuum cleaner or cool air blower to remove dust and debris from the printer’s interior, avoiding contamination of the printhead.
Environmental Control
1. Temperature Regulation:
• Maintain the printer in an environment with a temperature range of 15°C–30°C. Extreme temperatures can affect ink behavior, either drying it too quickly or reducing its flow.
2. Humidity Control:
• Keep humidity levels between 40%–60%. Use a humidifier or dehumidifier to prevent the ink from drying out or becoming too moist.
By following these preventive measures, you can ensure consistent performance, extend the printhead’s lifespan, and reduce operational interruptions in your DTF printer.
