Roland VS-540 - Refurbishing Problems - Magenta

[Plotter-FIX]

Hi guys,

We’ve been working on refurbishing a Roland VS-540 for three days and have already performed several upgrades and maintenance tasks. Here’s a summary of what’s been done so far:

Maintenance and Repairs Performed:​

1. Lines and Components Cleaned:
   • Flushed all ink lines.
   • Thoroughly cleaned the valve-closing system.
2. New Components Installed:
   • New printhead installed.
   • Original Mimaki Cap-Top installed (tried three different Cap-Tops).
   • Original pump installed.
   • Replaced magenta seal (from the carriage to the circulation system).
   • Changed all magenta hoses except the main one inside the system.
3. System Adjustments:
   • Deactivated magenta circulation by directly connecting the hose (due to recurring issues with circulation).
   • Re-routed the magenta line to run via a single hose instead of the Y-connector system.
4. Testing and Troubleshooting:
   • Adjusted the station position.
   • Tested the system with an original damper for magenta.
   • Switched ink lines (cyan to magenta): Achieved full nozzle test temporarily, but the issue returned after the system was left overnight.
   • Tried using the second magenta line, but the problem persisted.
