What Are Common Errors in Linx Printers and How to Fix Them?

Linx Continuous Inkjet (CIJ) printers are known for their reliability and low maintenance, but like all industrial equipment, they can occasionally encounter errors. Understanding the most common issues and knowing how to address them quickly can minimize downtime and maintain high production efficiency.

1. Nozzle Blockage

Problem: Partial or complete blockage of the nozzle, leading to distorted or missing prints.

Causes: Dried ink residues, environmental dust, or incorrect shutdown procedures.

Solutions:

• Perform a manual nozzle clean using the Linx cleaning function.
• Use a lint-free cloth and recommended cleaning fluids to gently wipe the nozzle area.
• Ensure proper shutdown procedures are followed after each shift.

2. Ink Viscosity Error

Problem: Printer displays a viscosity warning or error, affecting print quality and consistency.

Causes: Solvent evaporation, contamination, or malfunctioning solvent pumps.

Solutions:

• Check solvent levels and top up if necessary.
• Replace aging or contaminated ink.
• Calibrate or replace solvent sensors as per the maintenance schedule.

3. Printhead Alignment Issues

Problem: Misaligned printing, skewed codes, or inconsistent character spacing.

Causes: Vibration, improper printhead mounting, or changes in conveyor speed.

Solutions:

• Realign the printhead horizontally and vertically according to the product line specifications.
• Stabilize mounting brackets to reduce vibration.
• Use encoder-based printing if conveyor speed fluctuates.

4. Ink System Pressure Faults

Problem: Printer reports low or high ink pressure, disrupting the ink stream stability.

Causes: Blocked filters, worn pumps, or damaged tubing.

Solutions:

• Replace ink and air filters according to the maintenance schedule.
• Inspect and replace damaged tubing or malfunctioning pumps.
• Perform a full system flush if blockages are detected.

5. Error Codes (e.g., Error 50, Error 87)

Problem: The printer shows specific error codes indicating faults in subsystems.

Causes and Solutions:

• Error 50: Viscosity control fault — check ink concentration, clean sensors.
• Error 87: Umbilical communication fault — inspect and secure all umbilical connections.
• Refer to the Linx manual for detailed error code interpretations.

Best Practices to Prevent Errors

• Perform daily cleaning routines even if the printer seems to be operating normally.
• Use genuine Linx fluids and consumables to avoid compatibility issues.
• Schedule regular preventive maintenance (PM) based on operation hours and environmental conditions.
• Train operators to recognize early signs of common issues before they cause full breakdowns.

FAQs

• Are Linx printers difficult to maintain? No, with simple daily checks and scheduled maintenance, Linx printers remain very reliable.
• Can I fix major errors myself? Minor troubleshooting can be handled in-house, but complex repairs should be performed by authorized service technicians.
