Guide for Evaluating All-In-One Toner Printer Cartridges 1. Scope 1.1 This guide is intended for use as a means to evaluate all-in-one toner printer cartridges. All-in-one cartridges contain a toner developer section and the OPC (organophotoconductor) section among other components. All-in-one cartridges are self-contained parts of printers that contain toner.

1.2 This guide provides a basis for comparing all-in-one printer cartridges such as new OEM cartridges and remanufactured cartridges for use in contract purchasing.

1.3 This guide is not intended to be all inclusive of the quality attributes of all-in-one printer cartridges. The purpose of this standard practice is to make simple, but useful, evaluations that can be used to determine basic print quality, packaging integrity, and yield for cost-per-page comparisons.

1.4 The package integrity portion of this practice is applied to all-in-one cartridges that require common carrier shipping.

1.5 This guide and its inclusive standard practices do not purport to address all of the safety concerns, if any, associated with use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the application of regulatory limitations prior to use.

Referenced Documents 2.1 ISTA - International Safe Transit Association - Integrity Test Procedure 1A, references ASTM: D999 (Vibration Testing of Shipping Containers), D5276 (Drop Test of Loaded Containers by Free Fall), D5487 (Simulated Drop of Loaded Containers by Shock Machines), D880 (Impact Testing for Shipping Containers and Systems), D4003 (Programmable Horizontal Impact Test for Shipping Containers and Systems)

2.2 ASTM F 1856 Standard Practice for Determining Toner Usage for Printer Cartridges

2.3 ANSI IT2.17-1995 Density Measurements- Part 4: Geometric Conditions for Reflection Density

2.4 ASTM F 335 Standard Terminology Relating to Electrostatic Copying 2.5 ASTM F 2036 Standard Test Method for Evaluation of Larger Area Density and Background on Electrophotographic Printers.

3. Description of Terms Specific to this Guide 3.1 Package integrity - as defined in ISTA 1A, Preface. 3.2 Yield - the estimated number of pages produced at 5% print coverage, as defined in ASTM F 1856 section 11.3.

3.3 5% print coverage - As per ASTM F1856, section 7.2 4. Summary of Guide 4.1 This guide is a series of integrated standardized tests that will provide an evaluation of an all-in-one printer cartridge for contract purposes. Cartridges that are not delivered via common carrier are not required to use the package integrity test. It is common practice for some cartridge suppliers to “ hand deliver” their products and this assumes a far less severe shipping environment. “Hand delivered” means the cartridge is transported and delivered by the producer of the cartridge.

4.2 These tests have a sequence of package integrity, image density, background, and estimated yield. Package integrity stresses the packaging of the cartridge first. If failure occurs during this phase, the sequence is halted to avoid potential printer damage from a damaged cartridge. Image density and background evaluations are performed between the test intervals for yield.

4.3 A comparison can be made among the different sources for all-in-one cartridges. A purchaser can specify minimum performance levels based on these test results in purchasing contracts.

5. Significance and Use 5.1 This guide can be used for the evaluation of OEM and remanufactured all-in-one toner cartridges for the purposes of contract specifications.

5.2 This guide is suitable for quality acceptance evaluations. 6. Interferences 6.1 Relative humidity and temperature can affect test results in all four test areas in this practice: image density, background, yield, and package integrity. Users of this guide should refer to the specific interferences described in ASTM F 1856, ASTM F 2036, and ISTA 1A. 6.2 In a comparative cartridge test the same test target and printer must be used. The number of characters, font, and font size have a direct affect on toner consumption.

6.3 The test targets should not produce uneven wear on the cartridge components as this may affect the test results.

6.4 Test printers should be in good mechanical and electrical condition. Preferably printers with a continuous history of preventative maintenance should be used.
