Abstract
A platen roller is placed in a fixture. A plurality of pressurizing rollers are placed in the fixture. At least one of the plurality of pressuring rollers applies a pressure to the platen roller to pre-age the roller. A platen roller is placed in a pressurized chamber. A hydrostatic pressure is applied to the platen roller to pre-age the roller. A pre-aging software program is executed to pre-age a platen roller. The printer is instructed to print a number of large format media prints. The printer is instructed to print a number of small format media prints. This cycling continues for either a pre-determined time or a threshold number of prints.

11. A method of pre-aging a platen roller, comprising:
-
placing the platen roller in a fixture;
placing a plurality of pressurizing rollers in the fixture; and
rotating the platen roller which results in one of the plurality of pressurizing rollers applying a pressure to the platen roller. - View Dependent Claims (12, 13, 14)

15. A fixture for pre-aging a platen roller, comprising:
-
a bottom plate;
a top plate;
a bottom right vertical support connected to the bottom plate;
a top right vertical support connected to the top plate;
a bottom left vertical support connected to the bottom plate;
a top left vertical support connected to the top plate;
a top pressuring roller connected via bearings to the top right vertical support and the top left vertical support;
at least two pressuring rollers connected via bearings to the bottom right vertical support and the top left vertical support; and
a platen roller placed in an opening of the bottom right vertical support and the top right vertical support which rotates and presses against the top pressuring roller and the at least two pressuring rollers. - View Dependent Claims (16, 17, 18)

19. A system for pre-aging a structure made of a low durometer material, comprising:
-
a first pressure apparatus to apply pressure to the structure to introduce compression set and compression stress relaxation; and
a second pressure apparatus to apply pressure to the structure to introduce the compression set and the compression stress relaxation. - View Dependent Claims (20, 21, 22, 23, 24)

25. A program code storage device, comprising:
-
a computer readable storage medium; and
computer readable program code stored on the computer readable storage medium, the computer readable program code including instructions, which when executed cause a printer to;
print a number of small format media sheets; and
print a number of large format media sheets in order to introduce compression set to a platen roller, wherein the mixing of printing of the small format media sheets and the large format media sheets pre-ages a platen roller in the printer to minimize an effect of compression set and compression stress relaxation on the printer after a pre-aging time period. - View Dependent Claims (26, 27, 28, 29)
