Daily Maintenance and Usage Precautions for Printheads
2025-05-22* Clean Working Environment
Regularly clean the printing area and media surface to prevent dust/contaminant buildup, which may clog nozzles.
* Height Adjustment Check
Before printing, verify the clearance between the carriage plate and media to avoid head strikes.
* Nozzle Check Pattern
After powering on, print a nozzle test pattern. If missing or misaligned jets are detected, perform an immediate cleaning cycle.
* Abnormality Handling
If print quality issues (e.g., banding, blurring) occur during operation, pause printing and initiate a head cleaning procedure.
* Idle Protection
If printing is paused or stopped for more than 5 minutes, ensure the printhead returns to the capping station or activates a maintenance spray (spit mode) to prevent drying.
Usage Precautions
1. Electrostatic Discharge (ESD) Protection (Primary Threat)
Risk:
Solution:
* Proper grounding: Use ≥4 sq. mm copper wires to ground the printer and computer separately, ensuring a common ground.
* Humidity control: Maintain ambient humidity at 40%-60%; use a humidifier if necessary.
2. Ink Quality
Risk:
Solution:
* Use OEM or high-reputation ink brands with precise filtration, optimal viscosity, and reliable humectants.
3. Physical Damage Prevention
Risk: Warped media may scratch nozzle plates, or ink pooling may obstruct jets.
Solution:
* Inspect media flatness before printing; replace/repair warped media guides.
* Periodically clean the printhead’s faceplate with lint-free swabs and approved cleaning fluid (avoid abrasive wiping).
4. Additional Critical Notes
Avoid Prolonged Inactivity:
Perform a sealing maintenance routine if the printhead is unused for extended periods.
Standardized Operation:
* Power off before manual cleaning to prevent electrical hazards.
* Rely on automated cleaning functions; excessive manual cleaning may degrade the printhead.
Maintenance Schedule Recommendations
Daily: Nozzle test + workspace cleaning.
Weekly: Grounding inspection + internal ink residue removal.
Monthly: Deep cleaning (adjust frequency based on usage).
