Common causes

  • 1Blockages in the ink supply lines.
  • 2Pressure sensor miscalibration.
  • 3Ink circulation pump or valve issues.
  • 4Air trapped in the ink circuit due to improper venting.

Solutions

Quick Diagnosis

The C4501 error appears when the UV ink pressure control system detects readings outside the operational range. Look for air bubbles in the supply lines.

Step-by-step Solution

  1. Verify ink levels and pressure on the operator interface.
  2. Execute a purge cycle from the system software.
  3. Inspect ink filters for potential blockages.
  4. Perform a pressure calibration through the technician menu.

Prevention and Maintenance

Strictly follow the filter replacement schedule and printhead cleaning procedures. Keep the print room environment temperature-controlled for consistent ink viscosity.

When to Call a Technician

This error demands specialized technician intervention due to the complexity of the UV printheads, which are precision components.
