20100092200 | OPTIMIZATION OF RELOAD PERFORMANCE FOR PRINTER DEVELOPMENT SYSTEMS WITH DONOR ROLLS - A method creates a printing image charge on a photoreceptor printing region of a photoreceptor within a printing apparatus and, simultaneously with the creating of the printing image charge, charges source patches on the photoreceptor outside the photoreceptor printing region. The method then transfers developer material from a donor roll to the photoreceptor. The source patches cause developer material to be removed from areas of the donor roll outside a donor roll printing region to create developer material-depleted regions. The method then reloads the donor roll with developer material using a magnetic brush and evaluates a reload function of the donor roll by characteristics of developer material on target patches with developer material in areas of the non-printing region of the photoreceptor adjacent the target patches. The method then alters the printing image charge to maintain the reload function within a predetermined range. | 2010-04-15 |

A processor of the non-reference printing device may identify the type of media and the profile for that media and then adjust the printing parameters for the non-reference printing device based on the profile and the offset in order to optimize the print quality. The profile may also include a parameter that is based on a temperature coefficient associated with the type of printer. | 2010-04-15 |
