Speed Testing Methods
Comprehensive performance evaluation across various document types and usage scenarios
Time to First Print (Warm-up Time)
Measures the time from power-on or sleep mode to the first page being printed.
Why It Matters: Critical for busy offices where the copier may enter sleep mode frequently
Test Methodology:
- Device is powered on from cold start or awakened from sleep mode
- Timer starts when the power button is pressed or wake signal is sent
- Timer stops when the first printed page exits the output tray
- Test is repeated 3 times and averaged for accuracy
- Results compared across Draft, Standard, and Fine quality modes
Time to First Copy/Scan
Evaluates how quickly the device can produce the first copy or complete the first scan from the document glass or ADF.
Why It Matters: Important for walk-up copy jobs and quick scanning tasks
Test Methodology:
- Document is placed on scanner glass or loaded into ADF
- Copy or scan command is initiated
- Timer starts when the start button is pressed
- Timer stops when first copy exits or scan completes
- Multiple iterations ensure consistent results
Text-Only Print Speed
Measures sustained printing speed using a standardized 5-page text document.
Why It Matters: Baseline performance metric for document-heavy environments
Test Methodology:
- Uses ISO/IEC 24734 standard test methodology
- Five identical pages of formatted text are printed
- Timing begins when first page enters printer
- Timing ends when last page reaches output tray
- Pages per minute (PPM) calculated from total time
- Test repeated minimum of 5 times for statistical validity
Mixed Text-and-Graphics Speed
Tests real-world performance using a 20-page PDF containing both text and graphics.
Why It Matters: Most accurate representation of typical office documents
Test Methodology:
- Standard 20-page test file with mixed content
- Includes text, charts, images, and formatted tables
- Processed through printer driver at default settings
- Speed measured for full document completion
- Performance compared against manufacturer claims
Photo-Printing Speed
Evaluates color accuracy and speed when printing high-resolution photos.
Why It Matters: Critical for marketing departments and design work
Test Methodology:
- Three high-resolution photo pages (300+ DPI)
- Full-color image content testing color gamut
- Print quality set to highest available setting
- Both speed and color accuracy evaluated
- Results measured in minutes per photo page
ADF Scanning/Copying Speed
Measures throughput when using the Automatic Document Feeder for multi-page documents.
Why It Matters: Essential for high-volume scanning operations
Test Methodology:
- Standard 25-page document loaded into ADF
- Scan/copy operation initiated
- Speed measured in images per minute (IPM)
- Tests both simplex and duplex modes
- Results reported separately for each mode
Quality Testing Methods
Rigorous evaluation of print and scan quality using industry-standard test patterns
Line Detail and Resolution
Tests the ability to reproduce fine lines and small text at various sizes.
Test Pattern Used:
ISO 12233 resolution chart and custom line patterns
Pass Criteria:
600 DPI optical resolution minimum, clean reproduction of 6pt text
Evaluation Points:
Color Detail and Resolution
Evaluates color accuracy, gamut coverage, and fine color detail reproduction.
Test Pattern Used:
IT8.7/4 color target and custom gradient patterns
Pass Criteria:
Delta E < 5 for standard colors, smooth gradients without banding
Evaluation Points:
Registration and Alignment
Tests mechanical precision and how well colors align in multi-pass printing.
Test Pattern Used:
Custom registration marks and alignment grids
Pass Criteria:
Color misregistration < 0.5mm, consistent margins within ±2mm
Evaluation Points:
Standard Test Documents
Carefully designed test files that simulate real-world usage patterns

Test Execution Process
Device Preparation
Each device is configured with factory default settings, loaded with manufacturer-specified consumables, and allowed to reach operating temperature before testing begins.
Multiple Test Runs
Each test is performed a minimum of 3-5 times to ensure statistical validity. Results are averaged, with outliers investigated and documented.
Quality Mode Comparison
Tests are conducted across all available print quality modes (Draft, Standard, Fine/Best) to understand the trade-offs between speed and output quality.
Data Analysis & Reporting
Results are compiled, analyzed for consistency, and compared against manufacturer specifications. Discrepancies are noted and verified through additional testing.
Real-World Validation
Beyond controlled tests, devices are evaluated in simulated office environments to validate performance under realistic conditions and usage patterns.
Important Testing Notes
- Environmental conditions (temperature, humidity) are controlled and documented for each test session
- All tests use genuine manufacturer consumables unless otherwise specified
- Network printing tests use Gigabit Ethernet connections to eliminate network bottlenecks
- Firmware versions are documented and devices are tested with the latest available firmware
- Results may vary based on document complexity, paper type, and environmental factors in your specific environment
