Overview
ISO 2775:1977 is an international standard established by the International Organization for Standardization (ISO) that defines the widths of one-time paper or plastic printing ribbons used in office and printing machines for information processing. The standard focuses on narrow ribbons with widths of 19 mm or less and also specifies the location of markings that indicate when a ribbon is nearing its end. This ensures compatibility, reliability, and effective operation of office machines like printers and typewriters using these ribbons.
Key Topics
- Ribbon Widths: Specifies principal widths for narrow one-time paper or plastic printing ribbons, ensuring dimensional consistency for office machines and printing devices.
- Measurement Method: Defines how widths should be measured - on flat, unstretched ribbons at multiple points to obtain an average width.
- Marking Location: Provides guidelines for the placement and design of end-of-ribbon markings to alert users before the ribbon runs out, facilitating uninterrupted printing operations.
- Compatibility: References ISO 2257 for fabric ribbon widths on spools to ensure cohesive use with existing mechanisms when applicable.
- Manufacturer Guidelines: Allows manufacturers discretion in choosing the nature, color, and design of ribbon end markings while maintaining visibility and functionality standards.
Applications
ISO 2775:1977 is particularly relevant for:
- Office Machines: Standardizes ribbons for typewriters, cash registers, and other data processing equipment requiring printing ribbons.
- Printing Devices: Ensures proper ribbon sizes for narrow-width printing tasks where one-time-use paper or plastic ribbons are preferred.
- Ribbon Manufacturing: Guides producers on acceptable ribbon widths, measurement practices, and marking placements to guarantee product consistency.
- Quality Control & Maintenance: Assists service providers and machine manufacturers in verifying ribbon dimensions and end-of-ribbon indicators, reducing downtime and improving user experience.
This standard supports interoperability and the smooth functioning of printing hardware by standardizing critical ribbon parameters.

- ISO 2257 – Office machines and printing machines used for information processing: Widths of fabric printing ribbons on spools. This directly complements ISO 2775 by specifying ribbon widths for fabric ribbons commonly used in office equipment.
- Other ISO standards related to office machines and data processing equipment that help establish uniform technical specifications and interoperability guidelines.
By adhering to ISO 2775:1977, manufacturers and users of office and printing machines can ensure the use of appropriately sized one-time printing ribbons with clear end-of-ribbon markings, promoting efficient and continuous printing processes across international markets.
