Abstract
A system for regulating the vacuum hold pressure in a printer based upon the physical characteristics of the print media that is directed through the printer. In one embodiment, the characteristic of a sheet of media is detected before or as the sheet reaches the carrier. The vacuum pressure level is thus regulated in response to the physical characteristic of the sheet, thereby to have applied to that particular media a level of vacuum pressure that prevents problems that arise when pressure levels are too low (for example, inadvertent shifting of the paper) or too high (for example, paper deformations that reduce print quality).
