ISO/IEC 19752:2017

Overview

ISO/IEC 19752:2017 - Information technology - Office equipment - Method for the determination of toner cartridge yield for monochromatic electrophotographic printers and multi‑function devices that contain printer components - defines a standardized laboratory test to measure toner cartridge page yield for monochrome electrophotographic (laser) print systems. The standard prescribes test setup, environmental conditions, test files, end‑of‑life criteria and the statistical method for deriving a declared page yield. It is intended for office‑class equipment (not high‑volume production or large format machines) and supersedes the 2004 edition.

Key topics and technical requirements

• Scope: Applies to toner‑containing cartridges (including all‑in‑one cartridges) and the printer portion of multifunction devices with a digital input‑printing path. Not a measure of print quality or reliability.
• End of life definitions: Two phenomena define end of life - fade (visible reduction in density) or toner out signal that stops printing.
• Sample size: Minimum test matrix of at least 9 cartridges run across at least 3 printers (3 cartridges × 3 engines); larger sample sizes recommended.
• Print mode: Semi‑continuous, simplex printing using a specified standard test page (Annex C).
• Environmental conditions: Controlled test room - average 23.0 °C ± 2 °C and 50 % RH ± 10 % (running averages recorded).
• Set‑up and rendering: Factory‑preset image/print quality settings; disable toner‑saving modes and duplexing; ensure fonts/graphics are rendered per test file.
• Yield declaration: Declared page yield is determined statistically (value at or below the lower 90 % confidence bound) from individual page yields (see Clause 6).
• Toner replenishment systems: Can be tested with specific procedural modifications noted in the standard.
• Reporting and annexes: Includes process flowchart, fade examples, a normative standard test page (Annex C) and a sample reporting form (Annex D).

Practical applications and users

• Printer and consumable manufacturers: Establish reproducible yield claims for product labeling and marketing.
• Independent test laboratories: Provide accredited yield measurements and compliance testing.
• Procurement officers and specification writers: Compare cartridge yields for total cost‑of‑ownership and purchasing decisions.
• Retailers and reviewers: Verify manufacturer claims and produce consumer guidance.
• Regulatory bodies and industry groups: Use standardized methodology for fair comparisons.
