CHARGER PROVIDING NON-UNIFORM ELECTROSTATIC HOLDING FORCE

摘要

A printer includes a transport belt having an electrically non-conducting surface adapted to transport a receiver medium sheet along a transport path from an upstream position to a downstream position. A charging subsystem is configured to add charge to the transport belt or the receiver medium sheet, thereby providing an electrostatic holding force. An inking subsystem is positioned downstream of the charging subsystem and deposits a pattern of ink on the receiver medium sheet. The charging subsystem provides a non-uniform charge on the receiver medium sheet such that the electrostatic holding force is higher in a sub-region of the receiver medium sheet than it is for other portions of the receiver medium sheet, thereby enabling the receiver medium sheet to expand as a result of ink being deposited by the inking subsystem.

1. A printer comprising:
a transport belt having an electrically non-conducting surface adapted to transport a receiver medium sheet along a transport path from an upstream position to a downstream position; a charging subsystem configured to add charge to the transport belt or the receiver medium sheet, thereby providing an electrostatic holding force between the transport belt and the receiver medium sheet; and an inking subsystem positioned downstream of the charging subsystem that deposits a pattern of ink on the receiver medium sheet; wherein the charging subsystem providing a non-uniform charge on the receiver medium sheet such that the electrostatic holding force is higher in a sub-region of the receiver medium sheet than it is for other portions of the receiver medium sheet such that the sub-region of the receiver medium sheet is held to the transport belt more tightly than the other portions of the receiver medium sheet, thereby enabling the receiver medium sheet to expand as a result of ink being deposited by the inking subsystem.
