Troubleshooting case examples
- Study how paper/board quality properties changed before and after a process change or a rebuild
- Locate components causing caliper, basis weight or gloss variations
- Uneven pressing, clogged felts and many more production line issues are visible in Tapio sensor data
- Solve calendering problems by identifying faulty rolls
- Investigate ends of CD profiles
- Determine if winder vibrations are coming from variations in the paper
- QCS accuracy verification - easy tools for comparison with external data
Analysis Services and Troubleshooting Consulting
Expert analysis services and troubleshooting consulting for paper machines and board machines and other production lines.
Maximize your production efficiency with Tapio’s specialized analysis and troubleshooting services for all paper and board grades. Whether you’re dealing with vibration issues, unexplained variations, or quality concerns, Tapio Measurement Technologies can help you identify and resolve the root causes quickly and effectively.
Why choose Tapio?
The expert team at Tapio Measurement Technologies has decades of experience of solving production problems in paper and board production. Vibration problems, unknown variations, quality issues – Tapio Analysis can reveal the source variations in paper or board.
Easy sample preparation
Send us your MD rolls or hand-cut CD strips, and we’ll take care of the rest. We offer flexible handling of MD rolls, including cutting them to size, so a specific size roll is not a requirement.

Tapio Analysis
Free and open source software for analysis of Tapio measurements
- Unique, powerful software for quality improvement and problem solving for any paper and board mill
- Comprehensive set of CD & MD analysis tools
- Locate problematic machine elements with spectral analysis tools
- Benchmarking, guarantee assessment, before/after rebuild verifications
- Also suitable for analysis of any online sensor data
- Tapio analysis tools approved by all major paper makers and paper machine builders
Tapio Analyzers measure the exact same point with all sensors. Studying the point correlation between channels can reveal multiple issues in the production line.
Separate and quantify CD and MD variations (Variance Component Analysis)
Comparison of true CD profile with QCS readings or any other provided CD data
Tapio Analyzers can pinpoint the source of variation
Tapio Analysis can be used to determine which machine elements are causing variations in the end product:
• Verification and calibration of QCS and other online measurement systems
• Stock approach, screens, fan pumps, etc.
• CD Basis Weight Actuators, Jet to Wire Ratio, Formation, Wire Uniformity & Marking
• Press vibration problems, Nip pressure uniformity, Felt condition
• CD profiles and connection to actuators
• Coaters, Size Presses
• IR Dryers
• CR Coat weight control
• Calendering uniformity
• Calender blackening
• Calender bearing vibration
Contact us (info@tapiotechnologies.com) to proceed with a Tapio Analysis, which we offer both as a laboratory service as well as sell analyzer systems and sensros.
Accurate CD profile measured with millimeter resolution from true CD strips
Spectral analysis tools to determine and quantify which rolls or other machine elements are causing variations
Paper and Board Analyzer systems
Tapio Measurement Technologies offers paper machine analyzers and measurement equipment suitable for the precision measurement of almost all paper and board grades as well as other suitable rolled products.
We offer two types of analyzer devices:
• Tapio Analyzer, a system for analysis of both CD and long MD samples
• Tapio Profiler, a smaller unit for analysis of CD samples and short MD samples
Both analyzers support the same sensors.
