Patent ID: 7894767

Claim:
A method for evaluating toner print quality for print quality features comprising density and fusability, the method comprising: a. providing a first blank page; b. generating at least one reference print sample; c. defining at least one density and fusability evaluation area; d. generating a first set of data by determining print density of the first blank page and by determining print density and fusability of the reference print sample at each of their respective density and fusability evaluation areas; e. providing a mechanical rub tester; f. rubbing the reference print sample against the first blank page using the mechanical rub tester; g. generating a second set of data by determining print densities and fusabilities of rubbed first blank page and rubbed reference print sample at each of their respective density and fusability evaluation areas; h. providing a second blank page; i. generating at least one test print sample; j. generating a third set of data by determining print density of the second blank page and by determining print density and fusability of the test print sample at each of their respective density and fusability evaluation areas; k. rubbing the test print sample against the second blank page using the mechanical rub tester; l. generating a fourth set of data by determining print densities and fusabilities of rubbed second blank page and rubbed test print sample at each of their respective density and fusability evaluation areas; and m. comparing the first and third sets of data or second and fourth sets of data, wherein after the first blank page and the reference print sample are rubbed against each other, each of them are scanned through a scanner connected to a computer having print quality evaluation software to obtain post-rub print density readings, and wherein after the second blank page and the test print sample are rubbed against each other, each of them are scanned through the scanner connected to the computer having the print quality evaluation software to obtain post-rub print density readings.
