Case Study: HP DesignJet T830 Critical System Failure Recovery
The Challenge: Complete System Failure
R & A Geoxxxx Sdn Bhd, a geotechnical engineering firm in Subang Jaya, faced a critical situation when their HP DesignJet T830 plotter completely failed to power on. For engineering firms that rely on precise technical drawings and survey maps, any downtime can halt project deliverables and impact client commitments.
The client contacted DPI Technology support on December 1st, 2025, reporting that their printer would not turn on. Our technical team immediately dispatched Senior Engineer to their office.
The Diagnosis: Multiple Critical Issues
Upon arrival at 10:28 AM, engineer performed a comprehensive diagnostic inspection. The situation was more complex than initially reported:
🔍 Primary Issue:
The Main PCA Board had completely failed, preventing the printer from powering on.
⚠️ Secondary Issue:
During inspection, the 729 Printhead was found to be leaking, which could have caused additional damage if left unaddressed.
📋 Technical Impact:
Without a functioning main board, the entire system was inoperable. The printhead leak also posed a risk of ink contamination and further component damage.
The Solution: Complete System Restoration
Since this HP DesignJet T830 was covered under "In Warranty Service", the main board replacement was handled at no cost to the client. However, the printhead had been purchased separately by the customer through our online store.
DPI Technology's comprehensive repair process:
- Main Board Replacement: Installed new Main PCA board (F9A28-67020) under warranty coverage.
- Printhead Replacement: Replaced the leaking HP DesignJet 729 printhead with a new unit.
- System Calibration: Performed printhead alignment procedures to ensure optimal print quality.
- Network Configuration: Set up IP address and configured scan folder for network connectivity.
- Quality Testing: Conducted comprehensive print and scan tests to verify full functionality.
The entire repair process was completed by 12:32 PM the same day—just over 2 hours from arrival to full system restoration.
